 [*01] \                        - Introduction -
--------\=====================================================================

Prey is a highly ambitious game developed by 3D Realms and Human Head studios.
You take on the role of a man named Tommy, a young Cherokee who is eager to
cut his roots and set out into the world. Unfortunately, during one seemingly
normal night at the Roundhouse bar, Earth is attacked by aliens who want to
annihilate every living thing on the planet. Sure, Prey doesn't have the most
original storyline, but it executes the scenario very well. Prey's storyline
is arguably one of the best seen in any FPS to date.

This guide was written based on my experiences with the Xbox 360 version of
Prey. It can still, however, be used in conjunction with the PC version of
the game, just ignore all of the mention of achievements and any reference to
the buttons on the Xbox 360 controller. As far as I know, the presence of
achievements in the Xbox 360 version and the control schemes of the two diffe-
rent versions of the game are the only real differences, so using this guide
with the PC version should be fine. I suggest that you do not read too far
ahead, as this guide does CONTAIN MAJOR SPOILERS!

I have implemented a search system that I highly suggest you utilize. It is
very simple to use and it will make your time navigating this guide a whole
lot easier. To use it, simply press [Ctrl]+[F] to bring up the Find menu. Use
the table of contents and type in the corresponding code for the section that
you want to jump to. Each quest sub-section has its own table of contents that
contains a list of all of the quests in that section as well. I hope you can
find the answers you are looking for... now on to the FAQ!

|+|-~-~-~-~-~-~-~-~-~-~-~-|       - WRENCH -       |-~-~-~-~-~-~-~-~-~-~-~-|+|
|+|~-~-~-~-~-~-~-~-~-~-~-~o=-=-=-=-=-=-=-=-=-=-=-=-o~-~-~-~-~-~-~-~-~-~-~-~|+|
 The Wrench is Prey's melee weapon. Not much to say about this one really.
 This weapon is found during the first level of the game "Last Call," it is
 found on the bar counter. The Wrench has two different types of attacks: The
 standard attack(pulling the right trigger) allows you to quickly swing the
 wrench if you continuously tap the right trigger. The second attack(press and
 hold down on the left trigger) allows you to bring down a powerful swing to
 bludgeon the enemy.

 In single player, you should only consider using the wrench at times when
 you find yourself completely out of ammo in all of your guns, or if you're
 trying to conserve ammo for an upcoming boss fight. The wrench works well
 against Fodder and normal Hunters, but against anything else you'll have a
 tough time. In multiplayer, you will always have a wrench in your inventory.
 The wrench can be useful in some situations, but you have to act fast with
 it if your opponent is using a gun. If you can get someone stuck in a corner
 and confuse them, you can probably take them out with the wrench.

|+|~-~-~-~-~-~-~-~-~-~-~-~o=-=-=-=-=-=-=-=-=-=-=-=-o~-~-~-~-~-~-~-~-~-~-~-~|+|
 The Hunter Rifle is the first gun that you find during the single player
 game, and you always start off with it when you spawn during a multiplayer
 match. The hunter rifle isn't the most powerful weapon when using its stand-
 and fire, but the hunter rifle really shines when you use it as a sniper
 rifle. Press the left trigger to look through the rifle's scope. While
 looking through the scope, use the left and right bumpers to zoom in and out
 respectively. While you are using the hunter rifle as a sniper rifle, it will
 require more ammunition unfortunately.

 In single player, this weapon will be very useful to you throughout the
 levels. You will probably find, as you progress further, that you are only
 using the hunter rifle for its sniper function. The hunter rifle is the only
 weapon in Prey that has a scope, so you have to use this weapon if you want
 to stand a chance against enemy snipers. In multiplayer, the hunter rifle
 is a little harder to use as a sniper rifle due to all of the lag that you
 are sure to experience. You can usually catch people off guard, if they're
 running towards you while you have the rifle out, quickly enter sniper mode
 and shoot them. One hit is usually enough to kill or bring them down to an
 inch of health.

|+|~-~-~-~-~-~-~-~-~-~-~-~o=-=-=-=-=-=-=-=-=-=-=-=-o~-~-~-~-~-~-~-~-~-~-~-~|+|
 Crawlers are the grenades in Prey. You can usually find crawlers during the
 single player mode on the ground throughout the levels. Crawler grenades have
 two different modes: Standard grenade mode(press the right trigger or the 'X'
 button while you have another weapon out) and proximity mode(press the left
 trigger, then throw the crawler.) While in proximity mode, a thrown crawler
 will stick to whatever it is thrown at, even people. When you throw them
 normally, they will bounce around until the explode, making it relatively
 hard to get a kill this way unless the enemy is in an enclosed area. Crawlers
 work well during boss battles, as you can throw them while they are set to
 proximity and they will stick to them, causing a fair amount of damage.

 In multiplayer, crawlers can be quite effective when used correctly. While
 in proximity mode, as mentioned before, you can throw the crawlers at someone
 and they will stick to that person. You can throw them in front of you when
 you're running from an opponent, you may be able to catch them off guard as
 they chase after you. If you place them in strategic locations, you may be
 able to catch someone off guard as well. Crawlers thrown using the right
 trigger or the 'X' button in enclosed spaces can also be effective if you're
 lucky.

|+|-~-~-~-~-~-~-~-~-~-~-~-|     - SPIRIT BOW -     |-~-~-~-~-~-~-~-~-~-~-~-|+|
|+|~-~-~-~-~-~-~-~-~-~-~-~o=-=-=-=-=-=-=-=-=-=-=-=-o~-~-~-~-~-~-~-~-~-~-~-~|+|
 The Spirit Bow is the weapon that you use while Spirit Walking. In single
 player, you first get the spirit bow in the "Rites of Passage" level. While
 in spirit form, you can use the bow to damage some enemies. It isn't partic-
 ularily powerful, but you can possibly pick off a few hunters before they
 realize that you're in the area. You can only use the spirit bow as long as
 your spirit health is full. Each time you shoot an arrow, the spirit meter
 will fall. Once your spirit meter has been completely depleted, you will not
 be able to use the bow anymore, but you can still spirit walk. Getting hit
 by enemies will also lower your spirit gauge. Spirit walking of course, will
 help solve puzzles, walk right through forcefields, over spirit bridges and
 much more. Just make sure that you spirit walk in a safe place away from
 enemies, you're body will be vulnerable and as soon as you are hit you will
 return to it.

 In multiplayer you can also spirit walk. This isn't quite as useful as it is
 in single player, but you can still use it when in the right situation. For
 example, if you are alone in a room(such as the bathroom in Roundhouse), you
 can spirit walk through the door to scout ahead, possibly killing an approac-
 hing opponent. In multiplayer however, you can only stay in spirit form for a
 limited amount of time, as the spirit meter continuously drops while you are
 spirit walking. When the spirit meter is completely depleted, you will be
 unable to spirit walk. You can recharge your spirit meter by picking up the
 energy of fallen enemies or by picking up spirit bags in multiplayer.

|+|-~-~-~-~-~-~-~-~-~-~-~-|     - LEECH GUN -      |-~-~-~-~-~-~-~-~-~-~-~-|+|
|+|~-~-~-~-~-~-~-~-~-~-~-~o=-=-=-=-=-=-=-=-=-=-=-=-o~-~-~-~-~-~-~-~-~-~-~-~|+|
 The Leech Gun is a relatively powerful weapon. You first find one near the
 end of the "Second Chances" level during the single player game. The leech
 gun is slightly different then the other weapons in the game, different as
 in the way that you recharge it. You will not find ammo pickups for the
 leech gun anywhere, instead there are special leech gun stations mounted on
 the walls or ceilings throughout the levels. This is where the leech gun's
 left trigger function is used. When you encounter one of these leech gun
 stations, take out the leech gun if it isn't out already and aim towards the
 station. Hold down the left trigger to suck in all of the energy from the
 station. Continue holding down on the left trigger until the weapon is compl-
 etely recharged.

 There are four different types of leech gun stations that you can find in the
 game. The most common one is the plasma leech gun station. You're leech gun
 is initially charged with plasma energy when you first pick it up. It's the
 leech gun station with the red energy emitting from it. Another type is the
 electricity leech gun station, the electricity energy that can be taken from
 these stations is very powerful. It is however slightly difficult to hit
 something with this kind of fire and it depletes very quickly. Aim well or
 stand close to your target if you want your shot to connect. The frost leech
 gun stations are arguably the least useful, as you have to get relatively
 close to your enemy for it to be effective. The final type of leech gun
 station that you will encounter in Prey is the sun beam station. This is the
 strongest type of leech gun ammo you can get. When used, a large beam will
 shoot out of the cannon, damaging anything in its path.

|+|~-~-~-~-~-~-~-~-~-~-~-~o=-=-=-=-=-=-=-=-=-=-=-=-o~-~-~-~-~-~-~-~-~-~-~-~|+|
 The AutoCannon is a powerful weapon. The AutoCannon is first found during
 your first boss battle with the Centurion during the "Sacrifices" level. 
 This weapon's right trigger attack is a standard machine gun fire and the
 left trigger attack is a grenade launcher. The AutoCannon is effective
 against most enemies and the grenades can be useful against some of the
 bosses. Basically, when you're facing off against a big enemy, hold down the
 right trigger and tap the left trigger. This will take almost anything down
 with relative ease.

|+|~-~-~-~-~-~-~-~-~-~-~-~o=-=-=-=-=-=-=-=-=-=-=-=-o~-~-~-~-~-~-~-~-~-~-~-~|+|
 The Acid Sprayer is a powerful weapon, depending on how close you are to
 your target when you shoot them. The acid sprayer, as the name implies,
 spits out acid towards whatever it is aimed towards. Akin to the blast sent
 out by a shotgun, the acid will cover a large area. The acid sprayer is
 effective against most enemies in the single player mode, it is especially
 effective against the lesser hunters if you are standing close to them and
 the acid hits them straight on. The acid sprayer's left trigger attack
 launches an exploding ball of acid, it does take awhile to reload the weapon
 after using this attack however.

|+|~-~-~-~-~-~-~-~-~-~-~-~o=-=-=-=-=-=-=-=-=-=-=-=-o~-~-~-~-~-~-~-~-~-~-~-~|+|
 This is Prey's rocket launcher. You can find this weapon during the "Follow-
 ing Her" level of the single player mode. The crawler launcher has two
 functions, one being the standard crawler launcher(press the right trigger)
 and the other function(using the left trigger) creates a cloud in front of
 you that acts as a shield against enemy fire and explosive. Anything that
 is shot into the shield will be absorbed, be careful because this applies to
 you as well. The shield doesn't stay up for long, but this function will be
 invaluable when you are up against explosive using opponents.

|+|~-~-~-~-~-~-~-~-~-~-~o-=-=-=-=-=-=-=-=-=-=-=-=-=-=o~-~-~-~-~-~-~-~-~-~-~|+|
 Hunters are the standard FPS enemies in Prey. They are the bipedal, rifle
 wielding enemies that you will encounter during most of the levels. Luckily,
 these guys aren't very powerful and can be taken out with almost any weapon.
 These enemies can get a little crafty, however. Sometimes they will throw
 crawlers towards you or throw flying projectiles that home in on you. They
 also make use of the hunter rifle's sniper function, using it to knock off
 large portions of your health and possibly killing you from a distance. When
 facing off against these hunter snipers, you'll just have to find some cover
 and use your own hunter rifle to pick them off before they can kill you.
 Their are two types of hunters: The lesser hunters that you see during the
 first have of the game and the greater hunters that you sometimes encounter
 during the second half. The Elite Hunters are a little hardier, but they act
 in the same manner as the lesser hunters for the most part.

|+|~-~-~-~-~-~-~-~-~-~-~o-=-=-=-=-=-=-=-=-=-=-=-=-=-=o~-~-~-~-~-~-~-~-~-~-~|+|
|+|-~-~-~-~-~-~-~-~-~-~-|         - FODDER -         |-~-~-~-~-~-~-~-~-~-~-|+|
|+|~-~-~-~-~-~-~-~-~-~-~o-=-=-=-=-=-=-=-=-=-=-=-=-=-=o~-~-~-~-~-~-~-~-~-~-~|+|
 Just as this enemy's name implies, these guys are ridiculously weak and serve
 as nothing more than a minor distraction from the bigger, tougher enemies.
 Fodder are the first enemies that you encounter in the single player game,
 and for good reason too since they are so ridiculously weak. Any weapon can
 be used to take these enemies out quickly, an left trigger swing and one
 quick right trigger swing with the wrench will kill them. Fodder are melee
 enemies, so they might catch you off guard sometimes, but the damage they
 deal is so miniscule it doesn't really make a difference.

|+|~-~-~-~-~-~-~-~-~-~-~o-=-=-=-=-=-=-=-=-=-=-=-=-=-=o~-~-~-~-~-~-~-~-~-~-~|+|
 Hounds are essentially bigger, stronger, faster versions of the fodder.
 They run at you and attack with their claws, which can deal a relatively
 large amount of damage. The strategy to use against these guys is the same
 as the strategies that you would use against any melee enemy, back up while
 they are running towards you and fire away. You will usually encounter hounds
 in areas with hunters, serving as a much bigger distraction than the fodder.

|+|~-~-~-~-~-~-~-~-~-~-~o-=-=-=-=-=-=-=-=-=-=-=-=-=-=o~-~-~-~-~-~-~-~-~-~-~|+|
|+|-~-~-~-~-~-~-~-~-~-~-|    - MUTILATED HUMANS -    |-~-~-~-~-~-~-~-~-~-~-|+|
|+|~-~-~-~-~-~-~-~-~-~-~o-=-=-=-=-=-=-=-=-=-=-=-=-=-=o~-~-~-~-~-~-~-~-~-~-~|+|
 Mutilated Humans are only a threat to you if you directly disturb them while
 they are working on whatever monotonous task they have been assigned to. If
 you shoot them or touch them they will turn on you. If you are in area and
 there are a bunch of them, unless they are standing in front of a touch 
 screen monitor that you need to use, there is no reason to kill them. If you
 do disturb them, you will find that there attacks are very weak. They will
 only use melee attack, so just back up away from the and blast at them until
 they go down.

|+|-~-~-~-~-~-~-~-~-~-~-|       - GASPLANTS -        |-~-~-~-~-~-~-~-~-~-~-|+|
|+|~-~-~-~-~-~-~-~-~-~-~o-=-=-=-=-=-=-=-=-=-=-=-=-=-=o~-~-~-~-~-~-~-~-~-~-~|+|
 You will only encounter these flying enemies a couple of times during the
 single player mode. They are giant flying balls of gas basically. When
 killed, acid will rain down from them. Because of this, make sure that you
 are not standing under this enemy when you kill them. Any weapon should be
 able to take these guys out fairly easily. The only attack that they have
 is hovering over you, grabbing you and rendering you incapacitated, hoisting
 you up into the air and then finally dropping and slashing you. This deals
 a relatively large amount of damage, so try your best to stay away from them.
 You will encounter these enemies while you are flying in the shuttle, be
 careful when you shoot them, make sure you are a good distance away from
 them to avoid damage to the shuttle.

 Drones are, in my opinion, one of the most annoying enemies in Prey. They
 are the obligatory flying enemy which always seem to be extra annoying in
 first person shooters. When you have to fight these guys outside of a shuttle
 things can get rather hectic. They fire plasma energy from their cannons
 which deals a fair amount of damage. When there are two or more drones in the
 same area, it makes things a whole lot worse. The acid sprayer is a good
 weapon to use against these guys, if you can manage to get close enough to
 them to get a good shot in. Explosives area also an option, but things are
 much easier if you battle these flying enemies in a shuttle, which you will
 most often have to. While in the shuttle, use the left trigger to attach the
 drone to the tractor beam. Now, with the drone directly in your sight, fire
 the cannons and destroy the thing.

|+|~-~-~-~-~-~-~-~-~-~-~o-=-=-=-=-=-=-=-=-=-=-=-=-=-=o~-~-~-~-~-~-~-~-~-~-~|+|
 Harvesters are the enemies that you will have to face most often during the
 second half of the game. There are two types of harvesters: The crawling
 variation and the flying variation. The flying, in my opinion, is the most
 annoying out of these two. The harvesters use crawler launchers, so as you
 can imagine this can make things rather tough. For the flying harvesters,
 you can use explosive weapons such as the crawler launcher to take them out
 easily. If you destroy the harvester's lower body, it will fall to the ground,
 watch out because the flying ones explode. The crawling harvesters are rather
 annoying as well, since they will usually use their crawler launcher to bring
 up a cloud when you throw explosives their way. A good weapon to use against
 any of these harvesters is the crawler launcher simply for the cloud shield
 that you can create with the left trigger. It will protect you against their
 attacks, preventing you from taking massive damage or getting killed by them.

|+|~-~-~-~-~-~-~-~-~-~-~o-=-=-=-=-=-=-=-=-=-=-=-=-=-=o~-~-~-~-~-~-~-~-~-~-~|+|
 Mutates are giant, mutated humans. They've been fused with some sort of
 monster, which explains their grisly appearance. Mutates are melee enemies,
 but unlike the fodder and hounds, you can't really out run them by backing
 up. They are very fast, they will charge at you and swing their scythe-like
 appendages at you. You will only face these guys once or twice during the
 single player game, fortunately. The best thing to do is dodge to the side
 when they charge towards you. If you're lucky, the monster's scythe will get
 stuck in the ground, allowing you to get a ton of free shots in. Of course,
 with one or more mutates in the area, things aren't this easy...

|+|~-~-~-~-~-~-~-~-~-~-~o-=-=-=-=-=-=-=-=-=-=-=-=-=-=o~-~-~-~-~-~-~-~-~-~-~|+|
 Centurions are massive, hulking enemies that you will encounter more than
 once in Prey. The first time you encounter a Centurion is during the first
 boss battle in the game. The next few times you encounter Centurions, they
 won't be quite as tough as the boss battle version. These guys have two Auto-
 Cannons as hands, which of course makes them formidable opponents. Try to
 find some cover or some higher ground when facing centurions, because their
 AutoCannon fire is rapid and it will quickly drain your health if you're
 out in the open. Crawlers as well as anything explosive is good to use
 against the centurions.

|...Last Call.........................................................[m01]..|
O============================================================================O
 Prey starts of with the hero, Tommy, belittling himself in front of a mirror
 in the restroom of a bar. Little does he realize, whatever his problems are
 now, things are about to get much, much worse. Once you gain control of the
 main character, there really isn't anything you can do in the back area of
 the reservation. Leave the restroom and attempt to enter the main area of the
 bar. Tommy's Grandfather, Enisi, will stop to have a short talk with you,
 when he is finished speaking you are free to exit into the main area of the
 bar.

 As you are probably aware, there are three secret achievements in Prey. All
 of these achievements can be unlocked by playing and winning/scoring a
 certain amount of money/points on the game machines in the bar. You can find
 these machines to the left of the main bar area. There is a Black Jack, Poker,
 slot, and Runeman machine. You can't get an achievement for playing the slot
 machine, so don't even bother. To unlock the Black Jack achievement, you must
 win over $250 dollars using the Black Jack machine. To unlock the Retro Gamer
 achievement, you need to score over 15,000 points on the Runeman arcade
 machine. Essentially a Pac-Man clone. Poker Face, the other secret achieve-
 ment, can be unlocked much more easily at another point in the game, so don't
 bother with that one now.

 If you are out to unlock achievements, you'll want to take the time to play
 these games and earn the amount of points needed to unlock these secret
 achievements. A tip for Black Jack: If you are having trouble winning over
 250 dollars using the machine legitly, wait until you have a decent amount of
 credits(50 or more) and then save your game. Bet as many credits as you have,
 if you lose simply load your last save game. If you win, save your game once
 more. Repeat this process until the achievement is unlocked. Sure, the
 loading times make this a very tedious process, but if you aren't very good
 at Black Jack, this is definitely an option you should consider.

                [Black Jack, achieved!] [Retro Gamer, achieved!]

 When you are ready to continue, shuffle over to the counter and speak to Jen.
 You've got a weapon now, a wrench. Not a particularly powerful weapon, but
 it will have to do for now. After Jen is done speaking, approach Enisi who is
 seated by the counter. Once you have spoken to Jen again, the men at the bar
 will start to give her trouble. This is where Tommy, eager to impress his
 love interest, steps in. Here's your first taste of combat, you've got a
 wrench and they've got their fists. They will go down easily, you can press
 and hold down the Left Trigger to release a powerful smash with the wrench
 that you are using. After the short skirmish, the invasion begins. There is
 nothing you can do but watch as the aliens destroy the bar and capture
 everyone inside.

 There's nothing you can do at this point but hang there helplessly as the
 machines haul you around the alien station. Eventually, a strange person will
 meddle with the machine, imminently breaking you free and throwing you to the
 ground below. Once you are free, proceed straight ahead. Crouch down and pass
 into the next area. The small creatures here that will attack you are called
 fodder. They are very easily dealt with while using any weapon, even your
 wrench. One LT swing and a quick regular RT swing of your wrench will take
 these guys right out. You will come to a closed door, to the left of this
 door is a touch screen, move the crosshair over it and press RT to open the
 door.
 
 Nothing but a couple of fodder in this area, locate the small entrance to the
 next area, crouch and walk through it. Crouch and move through the small door
 in the middle of the room, then turn around and move through it again to
 enter a whole new area. Pretty cool, eh? You'll see lot's of things like this
 in Prey. Move down these hallways until you come to another one of those door
 ways. Move behind it, crouch down and enter the new area. The door right in
 front of you will open when you approach it and a few fodder will come
 through. It is dark in this area, so as the game suggests, press down on the
 Right Thumbstick to turn on the lighter.

 You will see Jen again in one of the next areas, continue moving through
 these rooms until you see Enisi and you can't proceed. At this point, you
 will witness the grisly death of Enisi. The bars that were previously
 blocking your path will retract and a blue-illuminated portal will open.
 Step through this portal to move onto the next level.

O============================================================================O
 Look to your left in this area and you should be able to see another touch
 screen monitor. Approach the device, focus the crosshair on the screen and
 press the Right Trigger. Climb up the ramp in this area and turn to your
 left. Get your wrench ready, because you will encounter your first hunter in
 this area. This one is quite weak, just knock him a few times with the wrench
 and he'll go down. Grab his weapon when he is dead, now you finally have a
 gun to use. This is the rifle, not a very powerful weapon but it serves its
 purpose in the time that it is required. This weapon can also act as a sniper
 rifle, press and hold down on the Left Trigger to use the scope, the Left and
 Right Bumpers are used to zoom in and out respectively. It's a very effective
 weapon as a sniper rifle, but each shot consumes more ammo.

 Step through the strange opening into the next area where you will encounter
 another hunter, giving you a chance to try out your new rifle. Don't bother
 stepping through the portal that he stepped through, instead turn right.
 Focus the crosshair on the touch screen monitor and press RT to disable the
 energy shield. Step through, the door on the catwalk ahead cannot be opened,
 so turn to your right and jump down to the area below. This area contains a
 small blocked pit and an explosive, round object. Push against the round
 object and move it over the blocked pit. While it is on top of the pit, step
 back and shoot it until it explodes. When it explodes, the material blocking
 the pit will evaporate, allowing you to proceed.

 As you move through the next area, another portal will open up and a hunter
 will jump out. Kill the hunter, then look to your left. There is another
 hunter on the platform opposite, go into sniper mode with your rifle and take
 him out with a quick headshot. Go through the door at the end of the catwalk,
 you can open the small ammo container mounted on the wall to your left to
 take some additional ammunition for your rifle. Exit back to the previous
 area and locate the small space in the railing. Jump down to the area below,
 you will find a couple of Crawlers here, walk over them to pick them up.
 These are basically Prey's version of the grenade. While they aren't terribly
 useful in Prey's single player, you can still use them against some enemies
 to get an easy kill. You can press the 'X' button to throw them while you
 have another weapon out. While you have the crawlers out, you can press the
 Left Trigger to set them to proximity mode, but this function is quite
 useless in single player.

 Approach the blue illuminated walkway here, you will encounter these walkways
 frequently in Prey, so get used to it. While stepping on these walkways, you
 are attached to them. This meaning, you can follow them to whichever location
 they lead to, even if the path that they take is on the ceiling of the room
 you are currently in. While using one of these walkways, if you are hanging
 upside down don't jump, you will become detached from the walkway and fall
 down to whatever waits below. Anyway, follow the walkway up to the higher
 level, you can pick up some additional crawlers and some rifle ammo in the
 corner to your left here. There is a fodder in this area, and as you proceed
 a portal will open and a couple of hunters will step through. You can
 probably manage to take them both out with a couple of quick headshots as
 soon as you see them.

 Step onto the blue illuminated walkway, this time this one will lead you up
 onto the ceiling. Just remember, don't jump while you are hanging upside
 down! A couple of hunters will appear as you follow the walkway, so remain
 cautious. At one point, you should be able to spot a couple of fodder feeding
 on a corpse to your right, you can take them out while hanging upside down to
 avoid any resistance from them. There is a ammo container mounted on the wall
 as well as a health panel on the floor that you can use in this room. Move to
 the end of this area, a box will fall down and a fodder will jump out into
 the area. Once it is dead, crouch down and go through the box into the next
 area. Notice the small planet in the glass case to your right as you enter
 the room and go through the container straight ahead.

 Just continue heading forward until you drop down a hole and into the next
 area. This catwalk leads to another portal, step through and try your best
 to avoid the spitting things on the wall and the floor. On the next catwalk,
 you will encounter a mutilated human, these enemies usually won't attack you
 unless the monotonous task that they are performing is interrupted. Moving
 forward, you'll witness a survivor being attacked by a hunter. Step through
 the two doors, be cautious as in this are you will encounter a few enemies.
 One hunter and a couple of hounds. Hounds are, essentially, greater versions
 of the fodder. They deal more damage and can take a greater amount of damage,
 just continuously back up while they are approaching you and continue
 shooting.

 There is another ammo container mounted on the wall in this next area. Go
 through the door here and you will find yourself in a relatively large area.
 Locate the touch screen monitor here and press it. Once it is activated, turn
 to your right and step onto the blue illuminated walkway. Ignore the hunters
 that spawn on the floor below and continue following the walkway until you
 reach the end of the line. In this next room you will find several mutilated
 humans, you don't need to kill them as they aren't likely to attack you. Find
 one of the explosive, round objects in this room and push it towards the door
 in this room that is covered with a strange material. Destroy the explosive
 object once it is near the door and the material will be disappear. Step into
 the next area and take out the hunter that appears. In the next area, you
 will see a unsteady looking suspended bridge, run across it and grab the
 rifle ammo on the platform opposite and then jump back onto the bridge. Some
 enemies will appear and begin shooting at the bridge. It soon fall down,
 taking you with it.

|...Rites of Passage..................................................[m04]..|
O============================================================================O
 You will appear in a strange land, proceed forward and step through the brick
 wall once it removes itself. When you reach the fire, you will encounter
 Enisi, who explains that you are in the land of the ancients. After the old
 man is finished speaking, follow Talon over to the doorway in the distance.
 Step through it and follow the path until you reach a brick wall. You will
 hear Enisi's voice, he tells you that a test awaits you behind this door.
 Behind this door you will find some flames, which you can't get past in
 your regular form. After Enisi is done explaining, press the 'Y' button to
 enter Spirit Form. While in spirit form, you can freely move past the
 flames. When you are on the other side, focus the crosshair on the totem
 and press the Right Trigger to activate it. After this is done, press the
 'Y' button again to return to your body.

 After Enisi is done speaking, step through the next door once it removes
 itself. In this area you will see a bow surrounded by flames, enter spirit
 form and step through the flames. Touch the bow to take it and then return
 to your body. The bow is the weapon that Tommy can use to damage enemies
 while in spirit form. You will need to use the spirit walk in many different
 situations. It is also helpful to use if you want to scout ahead and take out
 a couple of enemies. Now at this point in the game, things become really easy
 combat wise. From now on, if you ever die, you will be transported back to
 the land of the ancients where you will have to complete a short bow and
 arrow "mini-game." Each red spirit you hit will replenish Tommy's health and
 each blue spirit you hit will replenish his spirit. This essentially makes it
 so that you never get a game over. This aspects makes the game WAY too easy,
 which is slightly upsetting for those of us looking for a challenge...

|...Second Chances....................................................[m05]..|
O============================================================================O
 The mysterious voice will enter Tommy's head speak to you again. After it is
 done speaking, push the round, explosive object in this room over the hole
 that is covered by the strange material. Back away and shoot the explosive
 object a few times. When it explodes, you are free to step forward and fall
 down the hole. You will encounter another energy shield as you move forward,
 the switch to deactivate it is on the opposite side this time. It is in
 situations like this that spirit walking becomes essential. Go into spirit
 form and walk through the energy shield, press the touch screen monitor to
 deactivate the energy shield, then return to your body. There are a few
 fodder in the distance, you should be able take them out from where you are
 without taking any damage.

 From now on Talon, your spirit guide, will follow you through the levels.
 Talon will land on points of interest such as touch screen monitors. Talon
 will also allow you to decipher the strange alien text that you see on the
 monitors in the station while he is perched on a monitor containing this
 text. Head straight, turn left and go through the door here. You'll come to
 another energy shield here, enter your spirit form and use the touch screen
 monitor denoted to the forcefield to deactivate it. Why not take out the
 hunter with your bow here as well. If the blue illuminated walkway in this
 room is disabled, use the touch screen monitor to the left of it to turn it
 on. As you move forward, some portals will appear and hunters will jump out,
 so remain vigilant.

 When you get to the end of the walkway, do not jump off! Stay right where
 you are, hanging over the small platform below. While hanging upside down
 at the end of the walkway over the platform, go into spirit form. Follow the
 catwalk, walk through the forcefield and activate the touch screen monitor.
 When you have used the touch screen monitor, return to your body. The switch
 that you pressed while in spirit form will move the piece of walkway that you
 are standing on across the pit. When it has attached itself to the other
 walkway, follow this walkway back to the ground. Go up the stairs and through
 the door to the left. In this room, you will find the Leech Gun.

 This is a relatively powerful weapon, even more so depending on what you
 leech into it. If you notice any leech gun stations mounted on the wall, take
 out your leech gun, aim towards the stations and hold down the left trigger
 to suck in the energy to use it as ammunition. There are different flavors of
 stations that you can use to recharge your leech gun. Right now it is on the
 standard plasma ammunition. Several hunters will spawn in your current area,
 allowing you to test out the weapon that you have just acquired. Go through
 the door that opened once the room is clear, you will see one of the aforeme-
 ntioned leech stations on the wall here. You can use your rifle to destroy
 the harmful tentacles on the ground here. At the end of this path, you will
 witness a rather disturbing scene involving the two children in the blocked
 area here.

 After the incident, move into the room. Exit this room through the passage
 here. If you want, you can use the leech station in this area to take in the
 frost ammo, but I suggest staying with plasma as you need to get relatively
 close for the frost to be effective. Go down the stairs past the leech gun
 station and run to your right. You will see two boxes, go through the one
 to your right, the one that you do not see a mirror image of Tommy in.
 You find yourself in a gravity changing room. To switch the gravity in this
 room, use your rifle to shoot one of the small glowing green panels on the
 walls. Your goal is to get onto the small platform that is behind you, it
 should be right behind you if you haven't turned since you entered this area.
 Shoot the glowing green panel above this platform, the room will shift and a
 small orange illuminated portal will open up.

 Following the catwalk in this next area, you will meet plenty of resistance.
 You need to be careful here, as there are hunters who will use the sniper
 function on their rifles, as well as some hunters who will throw some
 crawler grenades towards you. You can tell that a sniper has his eye on you
 when you see the red laser darting around the room. Take cover behind some
 boxes and use your own sniper rifle to take out the sniping hunters on the
 platform at the opposite end of this area. At the end of this catwalk, fall
 down the hole onto the platform below. Here, look up to the ceiling above
 you, shoot the glowing green gravity panel to switch the gravity. Move to the
 end of this area, stand so you are right hugging up against the strange slimy
 object. Shoot the gravity panel on the wall to your left here to switch the
 gravity. Move to the end of this area, be certain that you are standing on
 small blood covered iron panels. Shoot the gravity panel in the area above.
 If you were standing in the right area, you should be able to move along the
 small platforms and hop over to the hallway.

 You'll find, strangely, what is left of the bar. There are some hunters down
 below that you will have to fight, take a couple of them out from where you
 are. When you are ready to go down, look to the counter on the right side of
 the bar, aim and shoot the green glowing gravity panel to switch the gravity.
 Jump down to the bar area below, you will have to fight all of the hunters
 that will spawn in here before you can leave. There are some leech stations
 mounted on the walls around here, as well as some health panels behind the
 counter. Some of the hunters will spawn on a higher level in the bar and act
 as snipers, so keep an eye on the wooden platform on the left side of this
 room so you can take them out as soon as they appear. When they stop spawning
 a portal will open and it will stay open, allowing you to walk through it and
 proceed. Don't shoot! That's you... A blue portal will open up right in front
 of you, step through it to end the level.

 In the proceeding area you will meet up with Jen, there is nothing you can
 do here so proceed through the circular door. Locate the wallwalk activation
 touch screen monitor and use it to activate the wallwalk if it is disabled.
 Talon should lead you to it, it is a monitor mounted on the wall. Take out
 the hunter that spawns below as soon as possible, as he will quickly move
 towards the wallwalk activation touch screen in an attempt to deactivate it.
 Follow the wallwalk all the way into the next area. You will encounter
 several fodder in this area. There is another door being blocked by that
 strange material, as well as the explosive round object that you can use to
 remove the material so you can proceed. Push the object towards the door,
 back up and shoot at it a few times to remove the material. Go into spirit
 form and step through the forcefield, locate the mounted touch screen monitor
 and switch it off.

 Return to your body and proceed forward. You will meet a hunter in this area,
 so be cautious. Turn right from the door that you used to enter this room,
 follow the path here and turn left as soon as you can. A few more hunters in
 this area, nothing you aren't used to already. Enter the small doorway at the
 end of the walkway. Quickly turn to your right and take out the hound that is
 at the end there. Head straight, maneuver yourself past the pipes and fall
 down the hole into the area below. Switch on your lighter and follow this
 path until you reach the next big area. After you fall down the hole, you
 will have to fight off a hound, as well as a couple of hunters on the
 platform opposite. When the area is clear, look to the ceiling and shoot the
 glowing green gravity panel to switch the gravity in the area. Move so that
 you are standing over the platform that the two hunters were standing on and
 fire the gravity panel on the ceiling.

 Hit the two switches, follow the path to the left. You can find the poker
 machine from the bar here, this machine is basically rigged so that you can
 win over 250 dollars to unlock the achievement, so if you don't have this
 secret achievement yet, take the time now to unlock it. Just fiddle around
 with the machine and the achievement should be unlocked.

                            [Poker Face, achieved!]

 Grab any ammo in this room and exit back through the portal that you came
 from. Move straight through this room, the platform that you are standing
 on will act as an elevator. It's a slow ride up. When the elevator reaches
 its destination, take the ammo from the mounted ammo container on the wall
 to your left and move through the door straight ahead. Look to the ceiling
 and hit the green glowing gravity switch here. Fall through the orange portal
 on this level. Locate the central, blood-covered platform in this area. Here,
 you will have to face off against a legion of... children! Relax Mr. Thompson,
 they're ghost children, and it's just a game! There are a couple of leech gun
 stations mounted on the wall that will allow you to load up your leech gun
 with plasma ammo. You must stand your ground in this area and fight off the
 ghost children that attack you. Plasma seems to work well on them, just spin
 around the platform and attack any of them that climb on, while trying your
 best to avoid the projectiles that they launch towards you.

 When the ghost children have stopped spawning, locate the small opening in
 the wall, crouch down and move into the next area. Once again, you will hear
 the mysterious voice. Once it is finished speaking to you, a blue portal will
 open up, step through it to finish the level.

|...Crash Landing.....................................................[m07]..|
O============================================================================O
 You begin this level behind a forcefield, you know what to do. Go into spirit
 form, move straight through the forcefield. Turn to your right and deactivate
 the forcefield via the touch screen monitor mounted on the pillar. Return to
 your body and clear out all of the hunters in this room. There is a mounted
 security turret on the ceiling in this room, so be careful. As soon as you
 see the multi-colored turrets, turn towards the turret and shoot it until
 it explodes. Your bullets will not damage the turret unless it is active and
 out of its metal casing. Once the hunters have stopped appearing in this
 room, locate the mounted touch screen monitor that will open a path for you
 and use it. Stand on the forcefield here, go into your spirit form and you
 will fall right through. Follow the walkway and use the touch screen monitor
 ahead to deactivate the forcefield, allowing your body to fall onto this
 level.

 Return to your body and move forward. Quickly take out the hunter that spawns
 on the platform above, then the one that appears below him. There is a mounted
 leech station that you can use to charge your leech gun with electricity. This
 is a very strong ammo for your leech gun, but you do have to aim well for the
 shot to connect. Leech the electricity and jump down past the pipes and into
 the area below. Kill the two hounds with the leech gun, a couple of floating
 gasplant will appear. The electricity stored in the leech gun will make short
 work of them and they are big targets, making them hard to miss. These enemies
 will attempt to fly over you and take hold, rendering you incapacitated. There
 are several mounted leech gun stations containing electricity in this area if
 you need to recharge your weapon, as the electricity runs out fairly quickly.
 The gas that these creature emit upon their death is damaging, so try you
 best not to kill one while it is hovering right above you.

 Some portals will open up on a platform with a couple of hunters acting as
 snipers. Quickly take them out with your own sniper rifle to avoid death,
 though death really isn't that bad of a thing in this game. Climb up the set
 of stairs leading up to the platform that sits right next to the platform
 with the orange portal. While standing on this platform, go into spirit form
 and walk up the bridge that appears while in this form. Use the touch screen
 monitor to lower the elevator that you are standing on. Return to your body
 and move onto the elevator, use the touch screen to raise yourself to the
 higher platform. Step through the orange portal and into the next area. Your
 path is quickly blocked by some bars, locate the gravity panel on the wall in
 this area, and shoot it. Move through the gap in the bars, move down to the
 very bottom of this area and shoot the gravity panel on the floor above.

 Some fodder will appear, take them out and use the touch screen next to the
 forcefield to deactivate it. You can take the rifle ammo from the mounted
 ammunition container on the wall in the area past the door. Stay in this main
 area and go into spirit form. Go past the doorway and hit the switch while in
 spirit form and then return to your body form. The small room that you were
 in will shift over to another area. Step out into this new area, you will
 encounter a couple of mutilated humans and a mounted security turret on the
 ceiling above the door at the end of the area. Clear the room and go through
 the doorway. You can recharge your leech gun via the mounted leech gun
 station in this room. Straight ahead there is a panel above the pipes blocked
 off by a forcefield.

 Hop up the pipes in spirit form and look at the monitor in this area. Though
 you cannot normally read the strange alien text, since Talon is with you, it
 will translate itself while you look at the monitor. The monitor displays a
 series of four numbers, memorize this code and return to your body. Locate
 the doorway with the touch screen monitor next to it, here is where you will
 need to enter the code that you observed on the monitor in that room. Use the
 touch screen to enter the combination of numbers. When the correct combinat-
 ion of numbers has been entered, the door next to the monitor will open. In
 this room there is another mounted security turret straight across from you,
 the leech gun loaded with electricity should be able to destroy it with one
 hit while it is active and out of its metal casing.

 Stand over the pit in the middle of this room and enter spirit form. Walk
 across the visible bridge over the pit. Look to the ceiling once you are on
 the opposite side and shoot the gravity panel that is in the hole. The
 gravity in the room will switch, return to your body and locate and fall
 through the hole in the floor if you haven't already. Follow this path to
 the end, at the end look up to the ceiling and shoot the gravity panel above.
 Step through the door now that you are on the opposite side, in this room you
 will find a couple of mounted leech gun stations. I suggest filling up your
 leech gun using the plasma station, as it will come in handy while you are in
 the next area. Take the rifle ammo from the mounted ammunition container on
 the wall and proceed through the door.

 In this next room you will be facing a couple of hounds and hunters, once the
 room is clear locate the forcefield blocked passage. While in spirit form,
 move through the forcefield and activate the switch in here to lower the
 elevator. Return to your body and place yourself on the elevator, while in
 position return to your spirit form, step through the forcefield and use
 the touch screen again. Return to your body once you have used the touch
 screen, the elevator will bring you up to the higher level in this area. Go
 through the door once the elevator has reached its destination. There is
 nothing in this area, move through the door ahead. Move down to the lower
 level, past the hanging corpses. On the higher level, a passage will rise up,
 crouch down and enter the next area.

 This room has a series of wallwalks, your goal is to get on the level that is
 right above the area that you entered into. Run across the little panels in
 the middle of the room, follow the wallwalk straight up onto the higher
 level. There is a mounted security turret as well as a hunter up here, take
 them out and then use the touch screen to activate the moving wallwalk
 panels. From your current position, follow the wallwalk down and turn left
 as soon as you can. Move straight across the series of moving wallwalk
 panels. You may have to wait until they stop moving, because if you standing
 or moving over one of the cracks while it is moving up/down, you will fall
 off. When you have reached the end of the moving wallwalk panels, climb down
 off of the wallwalk and go through the passage on this higher level.

 As soon as you enter the next area, the gravity switches around. There are
 some hunters on the ground below, as well as some mounted security turrets
 on the ceiling, which you are currently walking on. From the starting posi-
 tion of this area, head straight and turn left. Go through the box passage
 here. Kill off the hunters that you can see above and move around the box
 that you just entered through to find another square passage. Once you step
 through the passage, you will find that you are finally on the actual floor
 of this room. There is a door in this room, but you will need to first clear
 the room of all the hunters. Once they stop spawning, the door will open,
 some more hunters and a hound will come through.

 Before stepping through the door, look to the right of it for a monitor that
 is mounted on the wall. Look at it and a combination of four numbers will
 appear. Memorize this combination, then step through the door. Take the rifle
 ammo from the mounted ammunition container on the wall to the right if
 needed. Approach the touch screen monitor to the right of the door at the end
 of this room and use it to enter the four digit code. Don't step down from
 the platform just yet in the next area, look below and you should be able to
 see some hounds or fodder. Shoot them from above then jump down to the lower
 level. You will have to fight off some more hounds down here. When the area
 is clear, locate the wallwalk and activate it via the touch screen monitor to
 the right of it. Follow the wallwalk into the next area. In this room, use
 the touch screen to open a blue portal. Step through the portal to end the
 level.

 Move down the hall and clear out any mutilated humans or fodder that stand in
 your path. At the very end of this hall there is a monitor in the top corner
 of the wall. Focus on the monitor and you will see a four-digit code.
 Backtrack to the area that you first appeared in when this level began and
 locate the touch screen monitor. Enter the four-digit combination of numbers
 that you observed on the monitor at the end of the series of hallways. The
 square passage to the right of the monitor will open up, crouch down and walk
 through it. This area consists of a single walkway, on the side of it there
 is a single school bus. You can probably guess what is coming up next; yet
 another fight with the possessed children.

 Go into spirit form and climb up the visible bridge leading over the canyon.
 Use the touch screen monitor on the other side to open the passage at the
 end of the walkway. Not so fast, you can't proceed until you deal with the
 possessed ghost children. The children will appear on the walkway as well as
 near the school bus on the side of the walkway. Once they stop spawning,
 follow the walkway to the end, crouch down and go through the square passage.
 Follow the series of hallways here, you can find a mounted leech gun station
 on the walls of one of these hallways. Eventually you will come to a larger
 room, clear the room of the hunters that spawn here, hit the switch to
 activate the wallwalk and begin climbing. If you are quick enough, you can
 manage to kill the hunter that spawns just before he deactivates the wall
 walk. If not, you will fall down below. Kill the hunter, reactivate the wall-
 walk and proceed.

 There is some debris blocking the path of the initially activated wallwalk,
 so you will need to follow the deactivated one once it is activated, switch
 over to the other one through the gap and go through the orange portal. In
 this area you will find some fodder, as well as another one of those round
 explosive objects. When the room is clear of fodder, push the explosive
 object near the blocked hole in the ground. Step back, shoot the ball a few
 time and it will explode, clearing the path. Fall down the now accessible
 hole in the ground. Follow this path and turn right as soon as you are forced
 to. You will find a hunter in a pool of blood, as you step over it Tommy will
 retrieve the hunter's detached hand. You can now use this to open the doors
 that require hand identification. Approach the hand panel on the wall near
 the door and use the hand to activate it. Some fodder at the end of the path
 here, eventually you will find yourself overlooking a fight.

 | You're moments away from experiencing your first boss battle in Prey.     |
 | Since you can't really experience a game over in Prey, there isn't        |
 | anything to worry about here, but the Centurion does have some heavy      |
 | weapons in his arsenal which can make it rather difficult to accomplish   |
 | your task. As you look on, the human that the giant, hulking Centurion    |
 | is terrorizing, in an attempt to save himself, will jump up and grab on   |
 | to the cage that you are in. This ultimately causes the cage to fall      |
 | down, forcing you to face the giant Centurion. This ironically leads to   |
 | the man's demise.                                                         |
 |                                                                           |
 | As you can see the Centurion is a giant monster. He's as deadly as he     |
 | looks, if you stand to close to him he will swipe out at you, knocking    |
 | your health down a great deal. The Centurion uses two AutoCannons, which  |
 | are very powerful weapons. It has a standard machine gun fire, as well    |
 | as a secondary grenade launcher function. It is rather hard to avoid the  |
 | rapid fire from the AutoCannon, if you look in the corner of the room     |
 | you can spot several "safe" areas behind the pillars. In these little     |
 | areas you can find rifle ammo as well as some health spores on the floor  |
 | if you are in need of replenishing.                                       |
 |                                                                           |
 | You can use the pipes as cover, hide behind them and they will absorb     |
 | all of the AutoCannon fire. Try not to stand out in the open unless you   |
 | have to, the Centurion tends to use the grenade launcher on the Auto-     |
 | Cannon if you step out. Crawlers work really well against this guy, if    |
 | you have any in your inventory, take them out. While behind cover, wait   |
 | he stops shooting for a short period, pop out from behind the pipes and   |
 | hurl a crawler towards the beast. While you have the crawlers out, press  |
 | the Left Trigger to switch them to proximity mode. This way, when they    |
 | hit the beast, they will stick to him instead of bouncing off as they     |
 | normally do. If you don't have any crawlers or not a lot of them, you     |
 | just have to use another weapon in the same fashion. If you run out of    |
 | ammo, you will have to step out into the open to find some more rifle     |
 | ammunition behind another set of pipes.                                   |
 |                                                                           |
 | Some fodder will also be present during this battle, they are merely a    |
 | distraction but they can be quite annoying as they run behind the pipes   |
 | to get to you. Continue attacking him until you notice that one of the    |
 | small areas that was previously blocked by a forcefield is now opened.    |
 | You couldn't have really spirit walked through the forcefield while it's  |
 | on to switch it off, as you have to deal with the Centurion constantly    |
 | shooting at you. Run across the room once you notice that the force-      |
 | fields have been shut off and enter the small areas. Hide in the corner,  |
 | the Centurion will approach your area. Stand by the touch screen monitor  |
 | that will activate the forcefield and wait until the beast sticks his     |
 | hand in to try and shoot at you. At this point, use the touch screen to   |
 | activate the forcefield. This will cut off the Centurion's hand, allow-   |
 | ing you to retrieve the AutoCannon.                                       |
 |                                                                           |
 | This gun will make short work of the beast. With the AutoCannon in hand,  |
 | continuously fire at the Centurion while hurling grenades at him with     |
 | the Left Trigger. Watch as the Centurion's health depletes. Believe me,   |
 | he'll die in no time.                                                     |

 Once the Centurion is dead, an orange portal will open up. Step through it,
 you will encounter some hunters in this next area. Be careful, as some of
 them are likely to be throwing explosives towards you. Move to the end of the
 area, use the hand to activate the panel to the right of the wallwalk behind
 the forcefield. Follow the wallwalk all the way around, as you hang over the
 ceiling some hunters will spawn on the floor below and some will spawn in
 your path on the wallwalk. Kill the hunters and continue following the
 wallwalk until you reach the end.

 Use the alien hand to open the door via the hand identification panel right
 next to it. Continue moving forward until you reach the area with the large,
 spinning blue portal. Use the touch screen monitor in the middle of this room
 and fight off the hunters and hounds. When the room is clear and enemies stop
 spawning, the spinning, blue portal will straighten itself out. Step through
 the portal. Ignore harvester, an enemy that you haven't encountered yet, and
 move forward until you hear Enisi's voice. This will end the level.

 Follow the path to the fireplace and speak to Enisi. After a short conversa-
 tion, Enisi points you towards the spirit cave, where he claims to have
 something important to show you. Approach the door and follow the path to the
 spirit cave. Inside you will see a holographic representation of Jen, showing
 that she is indeed still alive. After another short conversation, you will be
 transported back to the alien world. The level ends.

 Run down the hallway, you will find a hunter and a couple of gasplants
 hovering above. Kill the enemies surrounding this area. The door that you
 want to go through is blocked off by some lasers. To disable the lasers, thus
 allowing you to proceed, follow the red wires around the tower. There are two
 hand identification panels that you need to use the alien hand on to disable
 the lasers. You can find an ammo container mounted on the back of the tower
 that contains some ammunition for your AutoCannon. Once you have deactivated
 the laser grid blocking the door, step into the elevator. There is a touch
 screen monitor in here that will allow you to move between the three floors
 of the tower. You are currently on the first floor. Unless you are looking
 for some addition ammo for your weapons, there is no need to ride the eleven-
 torn up to the third floor.

 On the second floor of the tower, you should be able to see a small, round
 platform straight ahead. Stand on the platform and a mechanism will appear.
 Focus on the mechanism and press the Right Trigger. This will spawn a flying
 craft, which you can use to move around this level. The controls are very
 straightforward and exactly what you would expect. There are some flying
 drones in this area and your craft can only take so much of a beating. To
 recharge the craft, land on one of the launch pads and press the Left Trigger
 to exit the shuttle. Get inside the shuttle again and it will be recharged.
 As soon as you enter the craft, look up to your right. You should be able to
 see a platform in the distance, as well as some fire. Fly up to the shuttle
 pad and press the Left Trigger to exit the shuttle.

 Move through the door on this platform and into the large area. Locate the
 ramp leading up to the higher level here, on the upper catwalk locate the
 touch screen monitor that will activate the wallwalk. Once the wallwalk has
 been activated and the room is clear of enemies, go onto the wallwalk and
 follow it until it throws you off. Hit the switches here, one of them will
 open up an orange portal. Step through the portal, this will simply lead you
 back to the lower level of this area. Exit back into the large outdoor area
 with the tower. In the distance, you should be able to see some flying drones
 appearing. Don't get into your shuttle just yet, you can easily take out
 these guys with your AutoCannon. To kill these enemies while in the shuttle,
 You can direct the tractor beam towards them by pressing and holding down on
 the Left Trigger. Press the Right Trigger to fire at the drone, which is now
 directly in your sight. If you ship is getting damaged, you can also stop
 back off at the shuttle pad and restore its armor.

 Use the shuttle to fly up to the higher level of the platform, to the right
 of the flames. Use the tractor beam to move the debris by pressing and
 holding down on the Left Trigger, while the crosshair is focused on the
 objects in your path. Go through the gate and exit the shuttle via the
 shuttle pad in the middle of this room. Go through the door to your left,
 down this hall you will encounter a couple of hunters and a hound. Follow the
 hall until you reach the touch screen monitor, activate it and then step
 through the orange portal that appears. Fly the ship out into the open and
 start heading up. Pilot the shuttle through the tube, you will run into a
 couple of flying drones along the way unfortunately. Continue down the tube,
 carefully maneuver the shuttle through the spinning rings of electricity when
 you come to them. Eventually you will come to a section that has two tubes
 running parallel to each other. There is one small section of the two tubes
 that rotates itself between them. Pilot the shuttle into this section when
 it is open, simply wait until the section rotates itself into the other tube.
 
 Continue following the tube until you reach a gate, the gate will open. Fly
 through it and into the next area. Ignore the enemies here for now and pilot
 the ship to the very bottom of this area. Another gate opens when you
 approach the floor, fly through the gate and land on the shuttle pad in the
 middle of this area. There are some flying drones as well as a sniper in the
 tower straight across from the shuttle pad. Move from side to side while
 killing the drones, attempting to avoid the sniper. When the drones are gone,
 quickly take out your own sniper rifle and take out the sniper in the tower
 across the area. Go through the door on this platform and hit the switch to
 the left. Before stepping through the orange portal that opens up, you can
 utilize either one of the leech gun stations to recharge your leech gun.
 Go through the portal and step onto the wallwalk. Follow the wallwalk until
 you reach the end, then hop off. There are hunters acting snipers in this
 area, so don't remain idle for long and quickly take them out.

 Go through the door at the end of this area and hit the touch screen monitor
 to the left. Step through the orange portal that opens up, hit the touch
 screen monitor to disable the forcefield blocking your progression. When you
 step back outside you will encounter some more flying drones. Damn drones.
 Destroy them, then approach the shuttle launch pad in the middle of the
 platform here and spawn a shuttle. Fly through the opening that was previou-
 sly blocked by a forcefield and land on the shuttle pad here. There are a few
 snipers here, take them out quickly to avoid death. Go through the door on 
 this platform and use the touch screen monitor to the left to spawn a blue
 portal. Step through this portal to move onto the next level.

 You'll likely have a couple of lasers directed towards you as soon as you
 through the door straight ahead. Take out your rifle and quickly pick off the
 hunter in the sniper tower across from you and the hunter below. Several more
 hunters will take the place of the one below the tower, so stand by while
 they spawn one after the other. When they stop spawning, step outside and go
 through the door to your left. On the walls in this hall there are several
 lasers. If you touch one of them, the mounted security turret on the ceiling
 at the end of the hall will activate. It is much easier to simply run to
 straight to the end of the hall, turn around and deactivate the lasers than
 it is to try and avoid them. If you do trip one of the lasers, quickly shoot
 at the mounted turret on the roof to avoid taking too much damage.

 Go through the first door to your right as you move down the hallway. Hit
 the touch screen monitor to your right to activate the wallwalk. Follow the
 wallwalk until you reach the end. Here, use the touch screen monitor to
 disable the forcefield blocking the door. Run through the hall to the very
 end. While behind the mounted security turret, if you touched a laser and
 it is out, shoot it while it is facing away from you. In the next room, you
 will encounter a flying harvester. These guys can be quite deadly, but their
 missiles are fairly easy to dodge if you have enough space to move around.
 They do tend to move around a lot, which makes them rather annoying. Kill
 the fat rocket launching enemy, cross the bridge and go through the door.
 Run down this hall, destroy the mounted security turret and deactivate the
 moving lasers. Ignore the door to the right in this hall for now and instead
 exit through the door at the end of the hall.

 Use the touch screen monitor to the left to open up an orange portal. Step
 through the portal and use the touch screen monitor in this tower to activate
 the wallwalk below. There are some sniping hunters on the bridge across from
 your current position, take them out so they don't bother you in the future.
 A few more hunters will probably spawn now, as well as a flying harvester.
 Take all of these enemies down, when they stop spawning turn around and go
 back through the orange portal. Go down the hall and this time exit through
 the first door to your left. Enter spirit form, step through the forcefield
 and use the touch screen monitor to your left to deactivate the forcefield.
 Stay in spirit form, cross the visible bridge and activate the wallwalk on
 this side of the area via the touch screen monitor. Step onto the wallwalk
 and follow it around to the other side. Go through the door, run down to the
 end of the hall, destroy the mounted security turret and switch off the eye
 stalks with the touch screen monitor.

 Through the door at the end of this hall, you will encounter yet another
 flying harvester. Be careful before you step out, as this guy's missiles are
 deadly if they connect. When the coast is clear, walk along the wallwalk
 to your left. Follow this wallwalk until you reach then end, then hop off.
 Walk along the pipes here and jump down below, being careful to make sure
 that land on the walkway below. Move straight across the bridge, through the
 door and into the next area. Kill the hunter in here and get onto the shut-
 tle. Fly the shuttle out through the gate, locate the blue shuttle pad and
 land here. Make sure that there are no snipers or regular hunters around and
 enter spirit form. Take the visible bridge up to the sniper tower, activate
 the touch screen monitor and return to your human form.

 Return to your shuttle and fly up through the opening in the ceiling. Before
 you do anything in this area, kill every flying drone and hunter in this
 area. Now, to get through this area you need to turn off the fan that is
 spinning on the ceiling of this area. To turn off this fan, you need to stop
 all of the power that is going towards powering it. There are three power
 sources that you need to damage. Each one of these is blocked by a forcefield
 so all you need to do is fly the shuttle to each of these sites. Land on the
 shuttle pad at each of these areas, spirit walk through the forcefield and
 turn off the forcefield surrounding the site. With this done, return to your
 body, get back in the shuttle, aim the cannons at the metal panel in the 
 round object on the wall and fire. When the metal panel is destroyed, use
 the tractor beam to remove each of the power generators that were behind the
 metal panel. Do this to the three power stations and the fan will turn off,
 allowing you fly up into the next area. Two of these stations require you to
 hit another touch screen monitor to open the metal casing before you can
 shoot the metal panel behind it.

 When all of the power generators are removed from behind the metal panels the
 fan will stop. Fly up past the fan, follow this tunnel up, through the gate
 and into the next tunnel. You will encounter some flying drones in this
 tunnel as well as a couple of gasplants. Keep your distance from the gas-
 plants destroy all of the enemies in your path. Fly you ship towards the big
 tower in this next area, use the tractor beam to remove the debris in front
 of the gate. Land your shuttle and step into the next area. Head straight
 past the two guards, turn left, then at the split turn right. Move into this
 room and turn to your left. The guard standing by this door will soon step
 out of your way and allow you to pass. In this room, Elhult will reveal
 herself. Step onto the platform when you are able to. A relatively long
 conversation ensues at this points. After the conversation, a blue portal
 opens up in the distance. Get off of the platform when you have the chance
 and go through the blue portal to finish this level.

O============================================================================O
 Move through the first area, trying your best to avoid the eye stalks and
 activating the mounted security turret. As you enter the next room, you'll
 catch a small glimpse of the creature known as the Keeper. Use the alien hand
 on the panel to open the door down the hall. To the left and right of this
 room there are two rooms. Enter each of this rooms and destroy the blue
 power source capsules. When you destroy one of these, eye stalks in the room
 will activate. Try to avoid the lasers, because if you touch one a mounted
 security turret will activate. There are ammo containers in each of these
 rooms. Once both of the blue capsules have been destroyed, return to the
 middle room and take the Acid Sprayer from the table between the two pillars.

 Once you have the acid sprayer, some orange portals will open up and some
 hunters will step out. This is a good chance to test out your new gun. The
 acid sprayer is a really powerful weapon when it is directed right towards
 the target and used at close range. The acid sprayer should be able to kill
 a hunter with one spray if you are close enough. Eventually, the hunters
 will stop spawning and an orange portal will open up and remain open. Turn
 around and exit through the door right behind you. Kill the hunters, move
 around the wall and use the touch screen monitor to turn of the forcefield
 blocking your progression. Exit this room by the door that was previously
 blocked by the forcefield. In this room you will encounter some hunters, as
 well as a mounted security turret on the ceiling.

 At the end of this room your path is being blocked by a forcefield. To the
 left of the forcefield there is a small alcove. Step into the alcove then
 enter spirit form. Move around the circular walls until you come to another
 alcove with a touch screen monitor next to it. Use the touch screen monitor
 to shift the alcove. Remain in spirit form and move through the next force-
 field. Locate the touch screen monitor and use it to shift the alcove again.
 Kill the hunters, at the end of this hall there is a box that you can crouch
 and move through the enter a new area. Use the touch screen monitor to your
 left to turn on the screen and open up an orange portal straight across from
 you. Move around this area until you come across another orange portal. Go
 through the portal, in this room you will only encounter mutilated humans who
 won't attack you unless you interrupt them. Go to the area with the crate and
 monitor, to your right is a hole in the wall that you can crouch and pass
 through.

 In this room you will encounter some flying drones, if your acid sprayer
 still has some juice left you can take these guys out with a couple of well
 aimed shots. When the room is clear, go into spirit form and cross the
 visible bridge over the gap. Use the touch screen monitor on this side of
 the room to disable the forcefield blocking the wallwalk. Return to your body
 and follow the wallwalk to the middle section. Hop off of the wallwalk, be
 careful as there is a security turret right in front of you. Crouch down,
 follow the path and eventually you will come to a room full of pipes. Drop
 down the pipes and onto the ground below, move to the end of this area and
 shoot the gravity panel on the wall right next to you. Move around the room
 until you find a hole in the floor blocked by a forcefield. Stand on the
 forcefield and enter spirit form, shoot the gravity panel on the floor in
 front of the forcefield and use the touch screen monitor to deactivate it.

 Return to your body, shoot the gravity panels in this room so that the force-
 field "cage" in this room is aligned with the floor. Spirit walk through the
 forcefield cage and use the touch screen monitor on the wall to open up an
 orange portal in this room. Go through the orange portal, you'll see the
 Keeper again for a moment in this room. After the Keeper's appearance, look
 for a hole in the floor. Fall down the hole and follow the path to the
 outside area. On this platform you will have to battle some drones. There is
 some AutoCannon ammo in the corner here, so take it if needed. Once the
 spots stop appearing, a blue portal will open up. Step through this portal to
 end the level.

 Move ahead through this hall and in the next room you will run into a force-
 field blocking your path. Spirit walk through the forcefield, look at the
 floor for a number combination written in blood(2432) and enter this code
 into the touch screen monitor to deactivate the forcefield. Return to your
 body, if you need ammo/health you can crouch down and go through a small
 opening to the left of this room to retrieve some acid sprayer ammo and there
 is a health station on the wall here. Next, go through the door next to the
 monitor, you will see Jen down below. Crouch down and crawl through the vent
 to your right. Kill the hunters here, there is an ammunition container
 mounted on the wall here and you can also find a leech gun plasma station in
 the room at the south end of the hall.

 The door at the end of the hall will lead you to a room with a forcefield.
 Spirit walk through the forcefield and use the touch screen monitor right
 next to it to deactivate it. Kill the mutilated human at the end of the room
 and use the alien's hand on the panel. You will have to fight some mutants,
 these are rather tough. They are fast and their attacks are rather damaging,
 just keep your distance and use your AutoCannon's grenade launcher or
 crawlers if you have some. Try to move side to side away from their attacks
 rather than simply backing up and shooting them, their attacks are fast and
 hard to avoid. You will have to fight a couple of these beasts and then a
 couple of hounds. After you have killed all of the enemies, go through the
 door at the end of this room.

 Move ahead and spirit walk through the forcefield to your left. Follow the
 tunnel to its end and hop out. Killed the mutilated human to open the door
 at the end of the hall using the touch screen monitor. Return to your body
 and exit this hall through the door at the end. Move ahead and enter the
 small ammo and health room. Enter spirit form and exit this room, turn right
 and use the touch screen monitor to shift the room. Take the ammo from the
 ammunition container mounted on the wall and exit the room. Turn right and
 exit through the door here. Destroy the security turret to the right of the
 wallwalk and then follow the wallwalk to its end. Kill the hunters and go
 through the orange portal down this hall. You will have to fight another one
 of those mutants, this time however you can use your leech gun to take the
 electricity ammo from the leech gun station on the wall. This gun should be
 able to kill the thing in a couple of hits.

 Once the mutants are dead, a portal will appear in the middle of the room.
 Before you proceed, you can go through the area at the end of this room that
 was previously blocked by the forcefield, turn to your right and crouch down
 into this room to find some additional ammunition. Step through the portal
 and exit this hall. You'll find Jen in this room, use the touch screen
 monitor to release her from the contraption that she is imprisoned in. After
 a short conversation with Jen and a message from Elhuit, step through the
 blue portal in the next room to finish the level.

 After the short conversation, move ahead. A couple of hunters will break
 through the wall to your right, kill them and exit through the hole in the
 wall. Move through this hall, killing all of the hunters and hounds in your
 path. Run towards the end of this area, all while portals are opening up and
 hunters are jumping out. Hop down to the lower level of this area and start
 killing all of the hunters. There are a couple of ammunition containers
 mounted on the wall somewhere in this area, locate them and take the ammo
 because you'll be needing it. Once the initial volley of hunters has ceased,
 a blue portal will open up and a couple of centurions will step out.

 Don't worry, these guys aren't nearly as strong as the boss centurion that
 you faced at an earlier level. Hunters and hounds will also accompany each
 centurion. If you're having trouble avoiding getting killed, you can climb
 up to the mid-section of this area, which allows you to easily pick off the
 distraction enemies and avoid the centurion's attacks. Crawlers work well,
 as well as AutoCannon grenades. When every enemy has been killed and they
 stop appearing, you will witness Jen being taken away by an enemy. Great,
 not this crap again. After a short chat with the mysterious voice, step
 through the blue portal that opens up to move on to the next level.

|...Following Her.....................................................[m15]..|
O============================================================================O
 Take the ammo from the container at the end of the hall and use the touch
 screen monitor to activate the wallwalk here. Follow the wallwalk and go
 through the passage to your left. You can take the electricity ammo for your
 leech gun from the leech gun station on the ceiling in this room. Go through
 the orange portal in here and through the door straight ahead. Drop down to
 the area below, kill the hounds and hunters in here, then proceed through the
 door on this level. Spirit walk through the forcefield and hit "Floor 1" on
 the touch screen elevator control panel. Return to your body and climb onto
 the elevator to the left once it is down. Return to your spirit form, pass
 through the forcefield once more and this time select "Floor 2" to carry
 yourself up to the next level. Return to your body and wait for the elevator
 to reach the top.

 Exit through the door at the end of the elevator. Move through the hall and
 kill all of the hunters and fodder in this room. Use the touch screen monitor
 here to disable to eye stalks. Be sure to take the ammo from the two ammuni-
 tion containers mounted on the wall by the door. Step into the next room and
 drop down to the level below. In this area you will have to face several
 Harvesters. Harvesters are relatively powerful enemies, they use crawler
 launchers as their main weapon and they can also swipe at you to deal a good
 amount of damage. The harvesters will usually use their launcher's secondary
 function to create a shield to block any explosive ammo that you try to throw
 at them. Try your best to keep your distance from these guys, if you get to
 close they'll either claw at you or fire a highly damaging explosive towards
 you. Use the pillar in the middle of this room as a shield, maneuver around
 it to block the harvester's missiles. Occasionally pop out, shoot the enemy,
 then quickly dodge back behind the pillar.

 When the harvesters stop spawning, use one of the wallwalks on the sides to
 climb up to the mid-section of this room. Once on the mid-section, move
 around to the wallwalk connected to this section, follow it up into the next
 area. On a table straight ahead, grab the Crawler Launcher. This is a very
 powerful weapon that will definitely come in handy. Its secondary function
 creates a shield in the air in front of you that will last for a short while.
 This shield will block any projectiles aimed at it while it lasts. Turn
 around and follow the path to your right. Kill the hunters here, when you
 reach the wall shoot the gravity panel on the ceiling above it to switch
 the gravity so you can pass over it. Pass the next wall that you encounter
 in the same fashion. Use the alien hand on the panel to open the door at the
 end of the hall and move on.

 This next area is...interesting. Wait until the large object is retracted so
 you can cross the metal grid to the other side. Jump through the window into
 the small room, kill the harvester and use the touch screen monitor in here.
 Step outside and you will encounter a couple of flying harvesters. This
 is the time to put your new launcher to good use, it'll take these guys out
 post-haste. Wait until the second large object is retracted, then hop over to
 the other side. Kill the hunters in your way and use the touch screen monitor
 mounted on the railing at the end of the walkway. After using this switch,
 wait until the moving object retracts, then hop onto the middle grid on the
 front. Ride the object and jump off of it just as you get close to the
 platform to your right.
 
 Wait until the beam of energy stops then quickly jump into the tube, turn
 left and start running. Immediately take a right as soon as you can. Kill the
 harvester in here, then move to the end of this area and through the door.
 Enter your spirit form and cross the now visible bridge over the gap. Head
 into the other room, press the switch to retract the bars. Return to your
 body, backtrack to the previous room and go through the door passed the newly
 retracted bars. You encounter a harvester and a flying enemy, clear out the
 room and hop down to the area below. Climb up the two metal platforms at the
 opposite end. Locate the explosive ball and push it towards the door with the
 strange material covering it. Step back, shoot the ball a few times to
 release the door. Go through the door, follow this hall and step through the
 blue portal at the end to move onto the next level.

|...The Complex.......................................................[m16]..|
O============================================================================O
 Use the alien hand to open the door at the end of the hall. As soon as that
 door opens you will likely have several lasers directed towards you. Take out
 your rifle and use it to snipe the sniping hunters that are gunning for you.
 At the end of this long, narrow area, drop down on the pipes. Crouch down
 and follow the pipes to another area. The area to the right houses some
 mutilated humans and some ammo, it ultimately leads to a dead end however.
 Take the wallwalk to the left, follow the wallwalk into the next area. Hit
 the switch in here to disable the eye stalks, then proceed through the door.
 Kill the hounds and the hunters in this area and follow the walkway around
 until you reach the end.

 Hop down the two platforms, wait until the cube is finished being built, then
 fall down the hole. This puzzle isn't as complex as it looks, your goal here
 is to fill the gaps in the cube using the small blue cube. As you can see,
 the interior of the cube is covered in gravity switches. These work just like
 the green glowing gravity panels you are used to seeing; shoot them and the
 gravity will shift in that direction. You need to switch the gravity in such
 a way that it will make the small blue cube in here fall down to fill up the
 gaps. So, start by standing on the gravity  switch and facing towards the
 gravity switch that the arm is pointing towards. Shoot the gravity switch on
 the wall ahead. See how the cube falls down to fill up the gaps? You need to
 do this enough times so that it falls all the way around the cube and reaches
 the second arm at the end.

 When you complete the cube puzzle, the cube will detach. Follow the wallwalk
 across from you all the way until it ends. Back at the beginning of the level
 again, cross the pipes once more to reach the platform with the strange,
 spinning object in the middle. Now that it is activated, step into it, you
 will be pushed to the upper level. There are a couple of harvesters here,
 as well as a flying one. Kill the harvesters and an orange portal will open
 up at the end of one of the catwalks. Step through the portal and stand on
 the first half of the catwalk in front of you. Spirit walk over to the switch
 mounted on the railing and press it. Return to your body, the two catwalks
 will connect to each other, move over to the second half and let it carry you
 over to the other side.

 Go through the door on this side of the area, spirit walk through the
 forcefield and use the switch to your left. This will switch the gravity in
 the room, return to your body and pass over the forcefield. Move to the very
 end of this room, so you are hugging up against the wall right near the arrow
 pointing up. The room will eventually switch itself back, at this point try
 to guide yourself as you are falling into the little opening in the wall.
 Alternatively, you can utilize the giant blocks in this room by pushing them
 past the forcefield while the gravity is switched, then pushing them together
 below the opening so you can hop up onto the small one and then onto the big
 one. The former method is a little faster if you get it right the first time,
 but either way they'll both get you out of this room and into the next area.

 This next area is a little confusing. This is a series of halls that can lead
 you around in circles if you're not careful. First, run around and kill the
 hunters patrolling this hallway. Now it's time to make your way out of here.
 Basically, if you see yourself in the distant section of the hallway, your
 going in the wrong direction. So if you ever see yourself, turn around and
 go the other way. Navigate the halls until you find a door that will lead you
 into the next area. Kill the harvesters in this room, then locate the touch
 screen monitor that will switch around the gravity. Locate the moving lift
 platforms and take one down to the next area.

 Follow the wallwalk and step through the orange portal at the end. Kill the
 flying enemies in here first and foremost. When they are dead, push the expl-
 osive ball near the strange material that you can see attached to the platf-
 orm straight ahead. When the material is destroyed, move over the platform
 and jump down to the grid below it. Go through the orange portal at the end
 of the bridge, take a shuttle and pilot it over to the platform that is
 diagonal the two catwalks with the hunters. Exit the shuttle and step through
 the door with the blue light over it. In this room you will find the blue
 portal, step through it to end the level.

 Spirit walk through the blue energy, past the laser grid and use the touch
 screen monitor to disable them. On the opposite side of this door, you will
 encounter some flying harvesters. Kill them and make your way to the opposite
 end of this area. Destroy the blue castle attached to the middle platform,
 then approach the door. Use the alien hand to open the door via the hand ide-
 ntification panel right next to it. Step through the door, move to the end of
 this room and use the switch near the door to power the shuttle elevator. Go
 into the next room. The strange voice will speak to you again, it will show
 you a holographical representation of the tower you are about to ascend. Yup,
 it's a long way up...

 Head back through the door that you used to enter this room once it opens 
 back up again. Exit back to the outside area and defeat the flying harvest-
 ers that have spawned. Move to the end of this side of the area and spawn
 a shuttle using the shuttle pad. Pilot the shuttle into the blue ring. This
 acts as an elevator, it will bring your shuttle up to a higher area. When you
 reach the top, use the shuttle's cannons to destroy the two mounted turrets,
 then exit the vehicle on the shuttle pad. There's an ammunition container in
 this area, as well as several different leech gun stations. Take what you
 like, then look around the area for a touch screen monitor. Use the monitor
 to unlock the gate at the top, return to the shuttle and pilot it up through
 the gate. All you need to do in this area is to get to the top and go through
 the gate. Avoid the mines and maybe hang back when the objects on the walls
 are shooting out blue energy.

 Kill the hunters in this area, then fly around the room and search for the
 small opening in the wall. Use the shuttle's tractor beam to pull the debris
 out of the way, then fly through it. Land the shuttle on the shuttle pad in
 the middle of this area. Kill the hunter and destroy the two security guns in
 the two top corners, then locate the hand identification panel and use the
 alien hand to unlock the gate. Get back on the shuttle and fly it out of the
 recently unlocked gate. Remove the debris tower and fly out into the open.
 Pilot the ship towards the planetoid in the middle of the area. Locate the
 shuttle pad on the top part of the planetoid and exit the shuttle. Defeat the
 flying drones. Follow the pipes that are connected to the area with the
 shuttle pad, when you reach the end press the switch. Follow the pipes back
 to the shuttle pad and board the shuttle again. Fly the shuttle to the
 platform with the blue ring elevator and exit the shuttle. Use the touch
 screen monitor to open the entrance to the elevator. Get back in the shuttle
 and fly it into the blue energy ring.

 Wait as the transporter slowly brings you to your destination. When you reach
 the end of the line, fly straight towards the platform ahead and exit the
 shuttle. Destroy the enemies up here, you can get some additional ammo up
 here as well. Locate the touch screen panel and press it to assemble another
 elevator. Enter a shuttle again and fly into the blue ring transporter. When
 the transporter reaches its destination, fly towards the shuttle pad and exit
 the shuttle. Move around this platform until you reach the gap. Shoot the
 green glowing gravity panel on the roof across from your side. Walk across to
 the other side, then shoot the gravity switch above to flip things back
 around. Destroy all of the enemies here, then spirit walk through the plasma
 discharge. Walk up the steps, jump through the forcefield and use the touch
 screen monitor here to turn of the plasma.

 Return to your body, jump up and walk through the tunnel. Walk through these
 halls until you come to a large room with a strange power source in the
 middle. There are four white beams of energy connected to it, simply shoot
 the blue capsules that the beams are coming from. After you have destroyed
 all of the blue capsules, exit this room and follow the hall. Eventually you
 will encounter some harvesters, kill them and then shoot the gravity switch
 on the ceiling. Locate the blue portal here and fall down it to end the
 level.

 Follow these halls until you reach a forcefield. Spirit walk past the force-
 field, hit the switch up ahead on the right to disable the forcefield. Return
 to your body and exit through the door ahead. Kill the hunters in here and
 Don't touch the switch in here yet, instead go through the orange portal and
 just ignore it for now. Stand on the elevator here and then enter spirit
 form. Spirit walk over the visible bridge leading over the gap to the other
 side and activate the touch screen monitor to open up an orange portal. This
 orange portal will lead you back to the previous room, so stay in spirit
 form and use the switch in here to lower the elevator that you are standing
 on. Crouch through the portal here and enter the next area.

 Find the hole in the floor and fall all the way down to the bottom. Destroy
 the security turret and the drones in this room, then look up and shoot the
 gravity switch. Be careful here, some pits of fire will open up, so walk
 around them. Position yourself so you are standing over the bridge with the
 gravity switch, then shoot the gravity switch again. Take the ammo from the
 ammunition container mounted on the wall here and then step back out. You will
 be in a new area now. Follow along the walkway until you reach the gap. Make
 sure that the flying harvester is dead before you spirit walk over the gap
 via the bridge. Use the switch on the other side to activate the wallwalk in
 this area. Move back past the door that you used to enter this area and take
 the wallwalk all the way to the opposite platform. Walk over to the shuttle
 pad that is on this side and spawn a shuttle.

 There are a couple of tractor beams in this area, aim the shuttle's cannons
 towards the devices that are shooting them beams on the walls and destroy
 them. Once they have been stopped, pilot the ship to the top of this area
 and exit into the next area through the two gates. Exit the shuttle on the
 shuttle pad in this area, kill the enemies around and then walk onto the pipe
 leading to the small planetoid. Walk around the planetoid until you are stan-
 ding over the platform that contains a touch screen monitor. The first
 platform that you are likely to see is the one with the shuttle pad, this is
 not the right platform as the monitor here is just a regular display monitor.
 Once you have located the platform with the touch screen, stand over it and
 enter Spirit form. You will fall through the forcefield, use the touch screen
 to turn off the forcefield and then return to your body. Next you will need
 to locate another touch screen monitor, this one is on a platform that also
 has a shuttle pad near it. Find it, it should be rather close to the one with
 the forcefield switch, and press the touch screen to open the tunnel in this
 area.
 
 Get back in the shuttle once the tunnel is open and fly up through it. This
 area contains two asteriods that are connected to each other with a couple of
 pipes. Locate the shuttle pad on the lower planet and exit the shuttle. Fight
 off the drones and then begin moving away from the platform. Just go continue
 moving straight, facing away from the shuttle's controls on the shuttle pad.
 Eventually, you will come to a part of the pipes that you can jump on and
 then follow them up to the upper planetoid. Press the touch screen monitor on
 the platform here, then follow the pipes back down to the shuttle pad on the
 planet below. Enter the shuttle and fly it up towards the plasma shooting
 objects that you should be able to see. Fly up near it and wait for the blue
 plasma to stop coming out, then quickly fly up the object and turn right as
 soon as you can to enter the next area.

 Here, you need to destroy this energy tower. There is a shuttle launch pad
 in this area, so land for a bit if your ship needs to recharge. To destroy
 the energy tower, you will need to destroy the little objects attached to the
 metal plates that are rotating around the tower. The objects as well as the
 tower itself will shoot electricity at you which causes a great amount of
 damage to your ship, so make sure that you use the shuttle pad to recharge
 if you need to. Once you have destroyed all of those objects and the metal
 plates have become detached from the tower, the rings in the middle of the
 tower will appear. Destroy each of these rings to destroy the tower. After
 the tower has exploded, pilot the ship up through the opening in the ceiling
 where the tower used to be attached to. Exit the ship on the shuttle pad here
 and step through the blue portal at the end of the walkway to finish the
 level.

 The voice in Tommy's head will halt your progress, once it is done speaking
 continue heading down the hallway. Eventually you will come to a room contai-
 ning another holographic representation of the tower that you are currently
 scaling. As you can see, you've still got a long way to go unfortunately.
 Once the voice is finished speaking, exit through the door on the opposite
 end of this room. As you attempt to cross the bridge in the next area, one
 of the tiles will enclose you within it. After the voice is finished and you
 are free, spirit walk across the visible bridge leading over the gap to the
 other side. Follow the walkway to the platform across from the one with your
 body currently on it and use the touch screen monitor. Return to your body,
 walk across the bridge and turn left. Stand on the square of wallwalk here.

 Spirit walk back over to the touch screen monitor and use it again. The
 piece of wallwalk that you are standing on will attach itself to the walkway
 on the level above. Return to your body and move onto the piece of wallwalk
 in front of you. Spirit walk over to the platform with the touch screen
 monitor ahead and use the monitor. Once the wallwalk with your body attached
 to it is on the opposite side, walk off of this wallwalk piece and stand on
 the one at the end of the walkway to your right. Spirit walk back over to the
 the touch screen monitor and use it again to transport your self up to the
 third level. Approach the portal and you will hear the keeper's voice again.
 Another orange portal will soon open up in the distance, when it does step
 through it to enter the next area. Stepping through this portal has brought
 you MUCH closer to your goal, as you can see by looking at the holographic
 representation of the tower.

 Exit this room through the door and step through the orange portal to enter
 the next area. In this area, you will encounter some harvesters. Also, the
 incredibly powerful sun beam can be sucked into your leech gun via the
 station on one of the walls. This makes your leech gun into an extremely
 powerful weapon, as becomes readily apparent when you fire the thing.
 While loaded with sun beam, the leech gun will fire out a beam of energy
 which will quickly kill any enemy that it is focused on. The beam is so powe-
 rful in fact, that firing the leech gun will cause you to be pushed back a
 bit. The sun beam is very effective against any enemy. There are a few harv-
 esters in this room as well as a security turret, this gives you the chance
 to test out the sun beam for yourself. When the room is clear, exit by the
 door at the end.

 There is another sun beam leech gun station in here, sweet. Use your current
 supply of sun beam to clear the room, then recharge your leech gun with this
 station. Use the touch screen monitor in this room. Return to the previous
 area and take the wallwalk down to the next area. Jump down off of the wall-
 walk and onto the lower level. You'll have to fight off some flying and
 ground harvesters here, nothing you aren't used to already. After the initial
 wave of harvesters however, thinks take a turn for the ugly. You will have to
 fight some mutants. There are several packs of ammo around here, so if you
 are in need of some just run around to the corners of the area. A blue portal
 will open up once the mutants are dead, step through it and run to the end of
 the hallway. It's Jen! After a short chat, you're forced to fight her.

 | Jen has been turned into some sort of genetic fusion between a human and  |
 | a monster. Not pretty. Although Jen is Tommy's love interest, she doesn't |
 | have control of the bottom half of her "body," and that half will waste   |
 | no time in attacking you. As soon as you gain control over Tommy again,   |
 | quickly back away from the capsule. This monster is very fast and his     |
 | melee attacks hurt. A lot. There isn't much you can do to get away from   |
 | him, besides back up but this is really a futile effort as he will indeed |
 | catch up with you and attempt to rip your face off. The monster has some  |
 | heavy fire power too, in the form of two sun beam cannons mounted on his  |
 | sides. Great.                                                             |
 |                                                                           |
 | You may be surprised, as this beast's health seems to fall rather quickly.|
 | While attempting to back away from him, use whatever weapon you have that |
 | will deal a good amount of damage. The acid sprayer seems to be quite     |
 | effective in this situation, but an AutoCannon's primary and secondary    |
 | fire is fine too. There is a catch however, when the monster's health     |
 | gets low enough, he'll whip out some flying objects that will replenish   |
 | his health supply. At this point, take out your biggest gun and begin     |
 | firing directly at the things. They are very effective and will recharge  |
 | him back to full health very quickly. You may need to bring down his life |
 | more than two times in order to destroy both of these objects, as they    |
 | can take a fair amount of punishment.                                     |
 |                                                                           |
 | When you destroy one of the objects, it will destroy one of the leech     |
 | guns at the monster's side. Once both of them have been destroyed, the    |
 | only thing your enemy can really do is run at you and attempt to throw    |
 | you across the room. Since the creature cannot recharge himself, this is  |
 | the final life bar that you have to deplete. So now just...shoot at it    |
 | until it dies. There are health spores on the floor as well as several    |
 | cases of acid sprayer and AutoCannon ammo, so really overall this boss    |
 | shouldn't be all too difficult. Once the beast is finally down, approach  |
 | its corpse with Jen still attached to it. Sadly, there is absolutely      |
 | nothing you can do to save Tommy's love, you must kill her to put her     |
 | out of her misery.                                                        |
 |                                                                           |

 Once Jen is gone, the voice will speak to you again. You are then transported
 back to the land of the ancients.

O============================================================================O
 Run down to the camp fire, where you will find Enisi. Once the old man is
 done speaking, go through the door leading to the spirit cave, follow the
 path and eventually you will come to a health upgrade. Once you've got your
 hand on that health upgrade, things take a turn for the worst. Somehow the
 dark ones have found their way to the land of the ancients. Ugh, follow the
 path out of the spirit cave to the outside area where you will find Enisi
 attempting to hold off the army of the dark. Once Enisi removes himself from
 the path, you'll have to fight off the enemies here.

 You will face a centurion, a bunch of drones, hunters and some harvesters.
 Luckily with the health upgrade it becomes a bit easier to go up against
 this many enemies at once. Be wary of the hunters that appear on the rocks
 surrounding this area. Eventually, once you have killed enough enemies, a
 blue portal will open up and it will stay open. Ignore all of the hunters
 that spawn here now and make a beeline towards the portal.

O============================================================================O
|...Facing the Enemy..................................................[m21]..|
O============================================================================O
 In this first area, you will have to face off against a multitude of enemies.
 All while shouting obscenities, apparently. There is a sun beam leech gun
 station one of the walls in this area, which you give you a few easy kills.
 There are also tons of health spores on the floor, as well as some ammo
 littered around the area. So in other words, you've got plenty of resources
 to use against these monsters. Eventually an orange portal will open and it
 will remain open, that's your ticket out of this area. Go through the orange
 portal and use the alien hand on the identification panel on the wall to
 open the door ahead. Quickly hit both of the switches here, then when the
 rotating object rotates with its opening towards you, fire at the white
 energy inside.
 
 Spirit walk across the visible bridge over the gap and hit the switch to
 raise the platform that you are on. Run down the hall across from you and
 use the alien hand on the panel to open the door right next to it. You will
 encounter a couple of flying harvesters in here, as well as the Keeper for
 a short time. Kill off all of the harvesters before you do anything. Kill
 the two hunter snipers that spawn above as well. When the room is clear,
 stand in front of one of the touch screen monitors. Enter spirit form and
 walk over to the other touch screen monitor and press on the screen. Now
 quickly switch back to your body and press on the screen that you are
 standing in front of. An elevator will come down, quickly run and step
 onto it. When it reaches the top, step off of the elevator and go through
 the door straight ahead.

 |                                                                           |
 | This is it, the battle with the Keeper. It become readily apparent that   |
 | the mysterious voice in Tommy's head was not the Keeper's, as he appears  |
 | to have believed. After a relatively long speech, the keeper will seat    |
 | himself on a platform over looking the arena. Up here, he is invulnerable.|
 | Before you can go head to head with the Keeper, you will need to battle   |
 | numerous enemies. Mutants, harvesters, hunters, the whole gang is here.   |
 | There are some plasma leech gun stations on the walls as well as several  |
 | health spores on the ground. This may be tough and you will probably die  |
 | at least once, but eventually the enemies will stop spawning, then you    |
 | will be able to face the Keeper. This isn't as exciting as it sounds,     |
 | unfortunately he's a real pushover.                                       |
 |                                                                           |
 | When the centurion falls down dead, the Keeper will hop down onto the     |
 | platform. This boss battle is just incredibly easy for being one of the   |
 | last bosses in the game. If he an attack other than firing two projecti-  |
 | les towards you, then I didn't notice them. Basically all you need to do  |
 | is stay a good distance away from him so you can avoid the projectiles    |
 | and attack him with anything you've got. Explosives, as always, work well |
 | against this guy. When you see a projectile coming towards you, just      |
 | dodge to the side, then move back into position and fire towards your     |
 | enemy. Beams of energy circulate around the area, so make sure that you   |
 | don't accidentally run into them. Continue firing at the creature until   |
 | he is dead. Once he is dead, you will hear the mysterious voice once      |
 | again, assuring you that it has just begun.                               |
 |                                                                           |

 The arena flips upside down, a portal opens up beneath you and you fall
 through to a new area. Past the two doors here, you will face some lesser
 keepers. They may appear to be slightly tougher than the boss version of a
 Keeper that you just faced, since while they are using their telekinesis to
 levitate an object they are invulnerable. You will encounter several keepers
 in the proceeding halls, it will be tough but since you can't get a game over
 in this game, you will eventually get through it. When you encounter a keeper
 stay a good distance away from it so you can avoid the projectiles and use
 the same strategy that you used against the Keeper boss. While they are using
 telekinesis, as mentioned earlier, they will be invulnerable. Get out of the
 way while they are levitating the object, as they will hurl it towards you.
 Of course, things will get tougher when there is more than one keeper in the
 area. Lucky for you, there are three sun beam leech gun stations on the wall
 in the first area, this'll fry those keepers with relative ease.

 Make sure that you take any ammo that you find from ammunition containers
 mounted on the walls, you will all the ammo that you can get for the final
 boss battle. There are more keepers in the second area, as well as an electr-
 icity leech gun station. Unfortunately, if the sun beam runs out you cannot
 return to the previous area so you can use one of the other sun beam leech
 gun stations to recharge your leech gun. You have to defeat all of the
 keepers before you can proceed into the next area. When all of the keepers
 in this area have been killed, head up the wallwalk and go through the door
 leading into the next area. There are a lot of keepers in this area, luckily
 there is another sun beam station right in front of the entrance. Kill a few
 of the keepers and then follow the wallwalk down to an orange portal.

 The proceeding hallway contains some hunters, hounds and a couple of keepers.
 If you've still got some sun beam in your leech gun, try your best to conse-
 rve this, because if you use it during the final boss battle, you'll have a
 much easier time with it. Kill all of the enemies that are in this hallway,
 then proceed into the next area. After a short chat with the mysterious voice
 in this area, a blue portal will be opened up. Step through this portal to
 complete this level.

 Enter the main room, once the voice speaks to you, the controls for a shuttle
 will form on the walkway. Approach the controls and board the shuttle. This
 is not your standard shuttle, you'll use it to energize the objects surroun-
 ding the outside of the planetoid in the middle of this area. The shuttle is
 slightly difficult to control, basically you use the Left Trigger and the
 Left Thumbstick pushed forward to propel the shuttle towards the planetoid,
 then you use the Right Trigger to create a stream of energy over one of the
 objects. The blue energy emitting from the device on the planetoid will
 change to a more powerful orange beam. Repeat this process until all of the
 blue beams have changed to orange beams. Once all of the blue beams have
 been converted, you will be transported into Mother's chamber.

 +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
 |                                                                           |
 | You're at the final battle, there's no turning back now! Here you will    |
 | Mother(zomg partial nudity!), she is the owner of the mysterious voice    |
 | that you have been hearing throughout the levels. Apparently, Mother      |
 | wants you to take her place as the controller of the metal world. Sorry,  |
 | not going to happen, Tommy's focused on destroying Mother to avenge       |
 | Jen's death. Once Mother is finished speaking, enter spirit form. The     |
 | goal here is to fire an arrow and hit each of the hexagon panes that make |
 | up the sphere that Mother is in. When each and every one of the hexagons  |
 | have been hit with an arrow, return to your body. Now use your rifle and  |
 | hit each pane until all of them are broken. Some hunters will spawn along |
 | the walkway, but they are easily dealt with. Once all of the hexagons     |
 | have been hit, Talon, you're faithful companion, will sacrifice himself   |
 | to help you take down Mother ;_;                                          |
 |                                                                           |
 | But it's not over yet, once Talon has done his thing you will be transp-  |
 | orted to a new area. The rest of the Mother boss battle is actually quite |
 | simple: On the sides of this platform, there are two structures with a    |
 | touch screen monitor next to each of them. What you must do is use the    |
 | touch screen monitors next to these structures to raise an explosive up   |
 | into the air. With the explosive object up in the air, take cover behind  |
 | the structure so it can absorb Mother's projectile attacks. If one of     |
 | them happens to be hit by a projectile, just send up another. Now, to     |
 | hurt Mother you first need to bring down her shields. To do this, wait    |
 | until Mother is in the air flying around close to one of the explosive    |
 | objects that you sent up. When she is close, fire at the explosive object |
 | (the crawler launcher works well, but another gun is fine too).           |
 |                                                                           |
 | If you did this correctly and Mother was close enough, her shields will   |
 | come down, leaving her vulnerable to your attacks. At this point, you've  |
 | only got a few seconds to deal some damage to her before she brings her   |
 | shields back up. If you still have some sun beam left in your leech gun   |
 | from the stage prior to this one, use this to drain Mother's health very  |
 | quickly. If not, any other gun is fine too, you can find a lot of ammo    |
 | scattered around the platform that you are fighting Mother on. Repeat     |
 | this process until Mother's health is completely gone.                    |
 |                                                                           |

 Once Mother has been defeated, she will attempt to convince Tommy to bond
 with the sphere in here place, promising him unimaginable power. Fortunately,
 Tommy's Grandfather talks some sense into him. Set the controls for the heart
 of the sun, the sphere is propelled straight into the glowing ball of fire
 and destroyed. That's it, you've completed Prey! Congratulations on a job
 well done! Enjoy the ending, you've earned it!

 You will receive the achievement for completing "Mother's Embrace" as well as
 the achievement for completing Prey on the normal difficulty setting. Now the
 Cherokee difficulty setting has been unlocked, complete this to unlock the
 "Galactic Hero" achievement. The only differences that I noticed between the
 two difficulties are that the enemies are stronger, and the absence of any
 health spores or health stations.
