    HL2-2 Intro
    Well this is one of my first full walkthroughs I'm going to do, I
    just felt like I'd start with something short and maybe start on some
    other games as they come out so I'll try my best.
    Don't repost this without my explicit consent. I probably won't have
    an issue as long as you ask me but please either im me on AIM at
    fatmikefatty or send me an email at my_crack_habit@hotmail.com. I'll
    respond asap to both but please do ask first and if you do get the ok
    to post it, please do not alter the guide in anyway and give me the
    right credit. Thanks.
    HL2-3 Overview
    This is a full Walkthrough and I have no included also the Controls
    that are defaulted and some small tips with them. The Weapons
    including some pertinent info about them, as well as an Enemies
    section which goes over the enemies in detail. Thanks for reading!
    HL2-4 Controls
    Here are all the controls, please do note these are all the default
    controls and you can set them up how you like. I will also include
    some small tips.
    Move Forward - W
    Move Backward - S
    Move Left (Strafe) - A
    Move Right (Strafe) - D
    These are your basic FPS movement keys, learn them well.
    Sprint - Shift
    Jump - Space
    Duck - Ctrl
    These are very common movement techniques you will be using, so if
    you arenít too well with them I would suggest just hoping around and
    using them.
    Primary Attack - Mouse 1 (Left click)
    Secondary Attack - Mouse 2 (Right click)
    Reload Weapon - R
    Use Item - E
    Gravity Gun - G
    Flashlight - F
    Suit Zoom - Z
    These are your basic functions you will obviously want to learn, the
    suit zoom is nice but I've never needed it, the others I use
    1 - Draw Crowbar
    2 - Draw Hand Gun / .357 Magnum
    3 - Draw SMG / Pulse Rifle
    4 - Draw Shotgun / Crossbow
    5 - Draw Grenade / RPG
    Last Weapon - Q
    You will probably be using these a lot, especially the Last Weapon
    button, so you can switch from your Gravity Gun to lets say...your SMG
    ...etc. To draw the second weapon hit the # twice.
    Other then that the last key you would probably use once in awhile is
    the Walk Key, defaulted as Alt.
    These are all basic controls, common with most FPS games so if you
    have played any before you should be quite familiar with them.
    The only true tip I have is that if you are making a jump that you
    aren't completely certain you will make, try ducking mid jump, it can
    help you make it onto the object you are jumping to, and definitely
    helps when jumping up things (to something higher then you).
    Again, if you aren't too confident with your controls and have just
    started or are in a safe area, just run around for a bit and get use
    to doing them with ease.
    HL2-5 Walkthrough
    Here we are, the story continues from the end of Half Life 2. It
    fades in with some debris dropping and a short speech by Dr. Breen.
    After that it cuts to the main scene where Half Life 2 ended, you see
    Alyx is frozen in time and then here some chanting. About a dozen of
    purple Vortigaunts warp in and continue the chanting and two move
    Alyx, she then wakes and then it fades to G-Man walking through a
    doorway and a few Vortigaunts chanting in front of him, as they pull
    you, Dr Gordon Freeman, away.
    HL2-5-A Chapter 1: Undue Alarm
    It fades in with your health at 47 and you hear Alyx and Dog but have
    bunches of rocks on top of you. As Dog pulls the rocks off you he
    notices you and pulls you from the rocks. Alyx notices that Dog has
    found you and starts speaking to you and then request that Dog give
    you the Gravity Gun. Walk forward and take the gun from Dog's hand
    and then listen as Alyx tells you briefly about what she remembers.
    As she is speaking you hear Eli Vance cut Alyx off and she heads off
    to relay back to him. Finally as you have control pull the few wooden
    blocks off the side so that the metal gate falls, making a walkway
    for you. Walk up, grab the med packs to refill your health and listen
    to what Alyx, Eli, and Dr Kliener have to say.
    After hearing what they have to say about the citadel and that you
    have to return back in to stabilize the core so that you can
    successfully leave the danger zone, continue forward towards the end
    of the downed Combine Gunship. As Dog moves it duck under to reach
    where Alyx is and continue on down. Jump down to the closest ledge,
    then head to the left and down again. Continue forward and duck under
    the pipes, as you do so you see some debris fall down and a small gap
    is created making you have to jump from ledge to ledge. It is a small
    jump but if you would like to be safe use your sprint (default as
    shift) and jump and you will definitely make it. Round the corner and
    duck under the pipes once again, you will face a car in front of you,
    use your gravity gun and use the main fire use of it to fire the car
    into falling off. After doing so, continue forward towards the fire
    and listen for some more information, and on how you will get into
    the citadel.
    During one of the scenes Dog disappears and tosses a car over, don't
    be afraid, it will not hurt you if you aren't quick, it should just
    push you aside. After having Alyx explain a little further and seeing
    her get in the driver side, head around to the passenger side and get
    in using the use button (defaulted as E). After Dog picks you up,
    enjoy the small scene as you land in the citadel, and then collapse
    the floor and go for one wild ride.
    Get out of the car using the use key again and now head to the left
    of where you get out, after the electricity shock and some debris
    fall, continue forward then left over the bridge. Follow the path
    through the hallway until you hit the loading screen. After this
    screen continue forward, you will be on a platform and can look
    around and get a true idea of how big the citadel is. After hearing
    Alyx comment on the drop, head to the left and drop to the floor
    where it is safe. Then continue on through the doorway. Continue
    forward and you will come into a room where there are one of the
    Combine gates blocking your way and in the other room you see some
    Stalkers, one fiddling with the computer console and another using
    its lasers to do some damage to something.
    After Alyx comments that she can't do anything with them in there
    she will unlock the door in the opposite corner of the door you need
    to get in and ask to check on the Roller Mines, believing that they
    may be your way to get through the door. Crawl across the ledge
    towards the dead stalker and go right, drop down onto the new ledge
    and take a look out. There will be a metal grating that is broken
    that you can land on, but once you land I suggest dropping down to
    your right because that grating will fall and will kill you if your
    are still on it. After dropping down, continue around the platform
    towards the elevator, after it comes down safely cross the elevator
    and continue around the other side of the platform, there will be a
    Combine scanner that would normally charge your suit, use it and it
    will charge not only your suit, but your health, and it will charge
    your suit at a greater rate and to 200, which is 100 higher then
    normal. Continue to the left and you will see the tube with the
    Roller Mines. Use your use button on the little goggle scanner and it
    will release the roller mines, you can punt the others, but make sure
    you grab one with your Gravity Gun and get on the elevator.
    After reaching the top go back to Alyx and she will explain that her
    dad taught her how to reset the targeting system on them to assist
    you but they are more unstable, meaning they will blow up eventually.
    After she explains that hold out the Roller Mine for her to reset it,
    it will turn a yellow color, after she does that toss it past the
    Combine security gate and into the room with the stalkers. It will
    roll around and kill both stalkers. After it does so Alyx will unlock
    the gate, you may want to wait for the roller mine to turn red and
    explode and then continue into the room. Once in the room continue
    the only open way and follow the hallway. You will come to a platform
    and see a dead stalker on it, continue to the left around the corner
    and Alyx will comment on how the soldiers are too busy trying to get
    out and that they may not see them. Continue on forward on the ledge
    and go left into the hallway. There will be some debris blocking you
    buy just duck under it and continue to the right.
    After ascending the stairs you will see a dead Combine soldier,
    continue right down the hallway and you will come into another
    hallway with a bunch of debris in your way. Just move it all out of
    the way with your gravity gun and continue forward. Then some
    electric shock will happen to the large thing over head and it
    becomes like a magnet, picking up everything that was under it. Then
    continue forward and left around the corner, down the hall and left
    again. Alyx will say how unstable the place is and say she doesn't
    want to be around much longer. Once you come to pretty much a dead
    end, get to the left of the small fencing and hop over it onto the
    ledge and continue to your right. Continue forward and a bridge will
    appear. You will see some Combine soldiers coming towards you, but
    don't fear, a vortex like thing combust and sucks them in and kills
    them. Here you will have to sprint across the bridge at the right
    time. Alyx will follow you after the vortex and make it safely as
    After crossing the bridge go right into the hallway and continue
    forward. Continue forward until you can make a left, do so and then
    hop over the small fencing and on the platform and watch as something
    weird gets ejected. Watch the small scene about the recording Dr.
    Breen had made and watch as alien like thing comes onto the screen
    and something comes up and you get hurt by some telekinesis type of
    damage. Although it looks like you get hurt, you actually do not.
    Once this happens continue on forward through the doorway.
    Continue down the hallway until there are some things on the side
    that pretty much put you in a 0 gravity type of suspension, this will
    charge your Gravity Gun, just like in Half Life 2. Now you have a
    Weapon that you can make some use of. Using the main fire weapon will
    instantly kill anything that is in close range but anything further
    it will not shoot out. The secondary use will pull things, even 
    Combine soldiers, to you. It is more effective on the enemy since it
    is easier to attack with it. After this happens continue forward and
    make a right, you will come to another loading spot. After this,
    continue down the hall and make a left to the ledge.
    From here you will see some energy orbs floating around and below you
    grab one and shoot it into the ball socket on the left to complete
    the bridge. Now cross the bridge, as you do so the tower in front of
    you will collapse, keep on going forward and some Combine soldiers
    will show up. Make easy work of them with your new gravity gun and
    then continue forward to the end of the ledge. Take a energy ball
    from the beam of energy below and shoot one into the left socket, and
    one into the right. After doing so you will complete a second bridge.
    Cross the bridge and kill the Combine soldiers again. Now you will
    have to make another bridge using the energy balls. This time the
    left socket is protected so just carefully aim to ricochet
    it off the wall behind the shield and bounce around and end up in the
    socket. Then shoot the right one as normal and cross the bridge. Duck
    under the debris and go right.
    Continue down this hallway and on your left there will be a small
    explosion, continue to the left now and then right into the new
    hallway. A few Combine soldiers will come through, make quick work of
    them, and continue forward. Once you come out to the ledge head left,
    thereís a small gap to cross, jump across and continue forward. There
    will be a soldier on the right shooting at you, but you can't reach
    him so just ignore it. A Combine ship will fly over you head holding
    a Strider, it will crash and Alyx will comment on this. Continue left
    towards where the ship crashed. Continue forward and then go right,
    you will see a small lighted are which you can go into on your right,
    head in there and Alyx will unlock the door. Continue down the hall
    until you get the loading notification. After it loads continue
    through the hall.
    After the hall ends, you come into a room with one energy orb and a
    platform. Alyx comments that it may be an elevator, which it is. Take
    the orb and shoot it into the socket across from the elevator, this
    will make the elevator active. Prepare for a fun ride here. Soon
    after you start heading down grab a energy ball, Alyx will say "Look
    up, watch out!" you will see a huge piece of debris, take careful
    aim and shoot the ball at it, it should knock it off course. There
    will be 2-3 more debris like that, if these debris hit the elevator
    it will knock it off and cause the death of both of you so just be
    aware. Alyx will usually warn you before the debris comes, so just
    keep an open ear and eye. As the elevator progresses you come to a
    stop and Alyx will ask whatís wrong.
    Thanks to Jake S. and others for letting me know of this (I did use
    it, but was having more luck with the energy balls.) They advised
    that you can easily just repel the large debris with the Gravity
    Gun once they get close enough, providing a better shot on them
    and keeping them away from the elevator.
    Thanks Jake and others.
    Across from you, you will see a room with a ball socket, there are
    some computer terminals blocking the only spot in, so pull those off
    and shoot a ball into the socket. It will continue down then come to
    a stop again. Here remove the computer terminals again and shoot
    another ball in. After doing so you will see some red lasers come
    onto the ball socket and you will be lifted back up a bit and then to
    a stop. A Stalker comes into view and is stopping you from
    continuing. Kill it using the ricochet method and a energy ball,
    after that, power up the ball socket and continue on down. Once you
    stop quickly get off because some very large debris will annihilate
    the elevator in total. Continue forward and there will be a suit
    charger on the right. Charge up and then go forward. One door will
    open then continue to the next, the first door will close and you are
    now done with Chapter 1. Onto chapter 2!
    HL2-5-B Chapter 2: Direct Intervention
    Continue forward and take care of the Combine soldiers as you
    progress. Alyx will punch some keys and a window will open and you
    can view the core, which I must say is beautifully done. Once she
    mentions the control room follow her, it was on the right side of the
    hall. Go in and Alyx will continue to talk then bring up an elevator,
    you must part with Alyx for a bit, get on the elevator and go down.
    After getting off you will be in the reactor room and there will be
    two stalkers you must take out before you can complete the bridges.
    After taking them out, there will be one slot directly forward from
    you and one above you, this will complete the first bridge. Cross
    over and there will be one across from you on the right side, shoot
    the energy ball in and continue on into the small room. Use your use
    key here and make the bridges go towards the central platform.
    Continue to the center platform and climb up the stairs.
    After getting up cross the bridge behind you and continue along the
    ledge and into the room. There will be some Combine soldiers in here,
    after clearing them out you can fill your energy and hp up at the
    suit charger. Get an energy ball and shoot it into the slot and an
    object will arise. After it comes up the door by the suit charger
    will open, some Combine soldiers will come in there and from behind
    (where the original Combine came from) some Manhacks will come out
    and a soldier or two. After clearing them continue down the new hall
    and it will be a dead end. There will be a small oven like door on
    your right that you can pull off with your Gravity Gun, do so and
    climb in.
    There's no real way to avoid the energy balls, but I'd suggest just
    sprinting and spamming the main fire of your gun to try to avoid them
    as much as possible.
    Kristopher C. sent me an E-mail saying you can use the oven like
    door as a shield against the energy balls, I have tried this and
    it works perfectly, just hold it as a shield with your gravity gun
    and the energy balls will hit it and dissipate.
    Thanks K.C.
    Run down this hall and into the left hall and continue on. You will
    come into a room with some Combine soldiers, make easy work of them
    and continue on out. Now you will have to cross another bridge and
    get dangerously close to the core. Be careful here, sprint across the
    platform and the second bridge and into the new hall. In here there
    will be some more Combine soldiers, kill them and shoot an energy
    ball into the socket and an object will arise.
    Continue through the new hall after the door opens. Kill the Combine
    soldiers that come out and continue down the hall and out. From here
    make a carefully planed jump onto one of the small rotating
    platforms. Some Manhacks will come out, make easy work of them then
    jump onto the ledge across from where you came from, its lower so
    just make a small jump and continue down the hall. Kill the Combine
    soldiers that come out and then continue into another small way
    blocked by one of those oven like doors. Continue through the hall
    here and into one of the rooms that has the energy balls shooting out
    at you. Repeat what you did last time and run down into the hallway
    on the left and into the room.
    Kill the Combine soldiers then grab an energy ball from the hall and
    shoot it into the socket. An object will rise up but then the machine
    malfunctions. The shielding where the object was has disappeared,
    jump down and you will see three objects that hold energy balls.
    There will be some pipes on the ceiling and crack in the ceiling
    where you can see into the hall with the energy balls. Simply grab
    them and shoot them into the objects. Shoot two in, for the third go
    back to where you jumped down into this room and fire it in. It will
    make the floor you are on rise up and you will just need to grab a
    energy ball and shoot it into the first socket.
    Some sort of reaction will happen and your gun will lose its powers.
    Continue through the door that opened and you will be back where Alyx
    is, the core has been contained for now. Alyx will explain some info
    so follow her as she speaks. After seeing the video with Dr. Judith
    Mossman you will see some weird tri-pod creature then the video cuts
    out. Alyx will make a copy of this and the packet they were trying to
    send then an alarm will go off. Follow her as she will open a way to
    an elevator for you to get out. Get on the elevator and continue on
    As the elevator comes to a stop get off and continue forward, some
    Combine soldiers will come out but just continue on and Alyx will
    lock the door. There will be a small explosion and two Roller Mines
    will come out, grab them and let Alyx reprogram them. Some Combine
    soldiers will come into the other room and then come open the door.
    Let the Roller Mines and Alyx kill them. After they are dead continue
    into that room and then onto the train after Alyx brings down the
    shield. After getting into the train you will notice it's a Stalker
    train, Alyx will talk and then the train will crash.
    After you regain control you will see the Stalkers are going crazy
    and Alyx is trapped. Go over to her and help her, use the pull
    function of your Gravity Gun to pull the stalker off her. Next to
    Alyx is the door, blast it open and jump down, Alyx will follow you
    and then continue under the wall and proceed to Chapter 3.
    HL2-5-C Chapter 3: Lowlife
    As this chapter starts, Alyx will request you wait a second while she
    catches her breath. After she does so she will unlock the Combine
    gate. Continue onto the right and you will see some turrets and a lot
    of dead Zombies. There's a few Head Craps, but let Alyx kill them.
    The turrets won't hurt you because they are out of ammo. If you want
    to speed things up, pick up a rock or cinder block with your Gravity
    Gun and use that as a weapon on the Zombies. There will be a few
    Hoppers as well, use these to your advantage here. Continue through
    this area and enter the door on the right.
    This hall will be extremely dark and so will the following areas so
    be prepared to make very good use of your flashlight (default key F).
    After you get to the end, you get to a door that is locked because
    the electricity to the door is not working. Find another way in, look
    to your right, you will see a small energy box and a vent, venture
    through the vent to get into the room. In the vent you can pull
    across some health and a flare, the flares aren't super useful, but
    they do help, just pull it or pick it up with your use button (not
    here though) and it will ignite. Now drop into the room.
    Once in the room there's a single head crap, just throw something at
    it or hit it with your main fire of your gravity gun. Now go to the
    cage...WEAPONS! Finally you get some real weapons. Use your gravity
    gun to get the Hand Gun and the Shotgun. Acquire the rest of the
    supplies in this room and then go to the fence and blast off the lock
    with one of your guns, I'd suggest the Hand Gun. In here there will be
    a control panel on your left, open it and then use your use key on it
    to activate the electricity opening both doors. Go to the door
    opposite where Alyx came and blast the car out of the way so you can
    get out.
    Now if you like, for most of these fights you can just use Alyx to
    your advantage by shining your light on the enemy so she attacks and
    you do...well nothing and conserve your ammo, but it's up to you.
    Once in this area there will initially be two Zombies, after they die
    go backwards and pick up the energy charge and the Shotgun ammo.
    Continue on killing the Zombies as they arise. Follow the dead Ant
    Lions until you finally see a live one, kill it and continue forward
    through the only door. In here you will get some supplies and see a
    Zombine (Combine turned Zombie) leaned against the wall. In the
    room in front of you the Zombine will come alive and run towards you
    with a grenade, just back away from the glass wall and it will blow
    up allowing you in and killing itself. Walk into here and go out the
    right exit.
    Another big area again, mainly advancing forward like before,
    Zombines will now come towards you, these aren't too tough but they
    can take some bullets, use the explosive drums to your advantage,
    they make easy work of the Zombines. Continue forward and you will
    eventually see another of the electronic doors on your left. Continue
    past it into a small entryway and there will be the electricity box,
    do as before and turn it on. Go back to the electric door and go
    through it. Climb up the stairs and the first entry to your left will
    be one of the annoying Black Head Crabs. It's easier to kill these
    yourself since Alyx may not be in position quick enough to kill it
    before it attacks you. There are two more Black Head Crabs in here,
    kill them, grab the supplies and continue forward.
    In here you will learn a key function to continue in the game, how to
    stop the Ant Lions from spawning. You will walk in and there wonít be
    any in here but there will be one of their holes. Once they start
    spawning, or if you really want to just put the car over it now, move
    the car over the pit to keep them trapped. Now use the wheel to
    lift the gate, a Black Head Crab will come out, but if you want to
    just drop the gate on it and it will die, now advance on in.
    Continue forward and a few Head Crabs will come out and then you will
    come to an area with a ton of the Barnacles, just throw some light on
    them and barrels and Alyx will shoot them. Wait some time though
    because some Zombies and Zombines will come and the Barnacles will
    make easy work of them so itís quite efficient. After the Zombies
    come just kill the rest off and advance through. Some more Zombines
    will be in here but grab the explosives and do as much damage. Once
    they are dead grab the health and Shotgun shells in the cracked wall,
    then continue through the double doors. Advance up the stairs and
    into the new area.
    This area can be quite annoying, there are 3 Ant Lion pits as well as
    Zombines attacking. Your main objective is to cover the Ant Lion pits
    as soon as you can. Once in the room some Zombines will come alive
    let Alyx and the Ant Lions kill them. To conserve ammo here I just
    used the gravity gun to knock back and kill some of the Ant Lions,
    since it helps much more then wasting your ammo on a limitless
    enemy. First run to the broken down red car and cover one of the pits
    with that. Now head to second level via a small concrete ramp. There
    will be a car through what looks like a window or door of an area and
    a supply box to the left of it, go in there and knock the car out,
    covering a second Ant Lion pit. Now back up to the second level and
    glance at the car across from you behind the gate, thatís your third
    car. Run over to the area, then turn around and climb to the third
    level. Up here head back towards where the car was and drop to it.
    Thereís a single Zombine here and it should pull out a grenade. After
    it is disposed of, open the gate and cover the third pit. Once the
    Ant Lions are controlled, search the area for supplies since there
    are a lot of them and then continue to the 3rd floor and go through
    the gate that is near where you dropped down for the last car.
    Continue down the steps.
    If you want thereís a supply box at the very bottom, but go through
    the doorway into the room filled with water. Kill the Zombines as
    they come and use the explosives to make quick work of them. Once
    through continue through the door into a large room that you will
    love (thatís sarcasm by the way). You'll see an elevator, but of
    course it breaks down. Now search the area first and you may want to
    collect all the explosives you can near the elevator. Once you are
    ready follow the wire from the elevator to a door that is a
    barricaded. Open the door and you will find a Zombine, once it is
    dead go inside and turn on the electricity and head back to the
    elevator for some fun. A lot of Zombies, the Leapers, and Zombines
    and be sure to constantly check both sides and try to keep the light
    near Alyx since she will assist you the most. Once the elevator
    arrives, hop on to advance to Chapter 4.
    HL2-5-D Chapter 4: Urban Flight
    As this chapter starts, exit the elevator and follow Alyx, you will
    notice that you are finally to the city, but still are trapped here
    since the gate is locked and thereís no wheel to open it. Head back
    towards the elevator and open this gate, there will be a wheel for
    the gate that is locked, pick it up with your use key or Gravity Gun
    and put it into the slot and open the gate and head up. Up the stairs
    and to your left, head backwards towards the sheet metal construction,
    remove the metal and continue on.
    Some Flashers will come down and blind you, just grab them and toss
    them to blow them up. Continue through this alley and you will come
    across some Combine soldiers who will scale the walls, kill them and
    grab their SMGs and ammo. Continue onwards to around the right
    corner. The large structure will move and you can continue out, there
    will be some rebels fighting Ant Lions and Combine soldiers, kill off
    the Combines and plug up the Ant Lion holes as quick as you can. Once
    its all clear grab any supplies and ammo and run forward from where
    you came, there will be a set of blue doors with some boards in front
    of them, remove the boards and open the doors.
    As the doors open you will see some Combine soldiers setting up some
    of the trip-mines, if you are quick just shoot one of the mines with
    a gun to have it explode and kill the soldiers. Now once in here,
    clear any other trip-mines and then grab any trash and rocks and junk
    and place it on close end of the piping in the other room in here
    (you will see a white propane like tank with a wheel). After piling
    up as much trash as you can, get on the piping and sprint across and
    jump across near the end of the piping and you should reach the
    ledge. If not, try again or find more junk to pile up so that it
    keeps the pipe steady and not tipping.
    Once you have shut off the gas, continue through where the flames
    were, in this room there will be some Zombies, one should walk
    through a trip-mine killing itself, then continue on, a Roller Mine
    should also pop out, I just shot it aside for the time because they
    aren't super helpful. Once you cross and go down the stairs there
    should be another Roller Mine, this one though is quite useful. Grab
    it and have Alyx reconfigure it. Once done run out side using the
    Roller Mine and the cars for coverage, once close enough, toss the
    Roller Mine into the window and it will kill the Sniper. Once done,
    there are some supply crates in the area where the sniper falls down
    to, break them open for some grenades.
    Now Alyx will climb up and pick up the rifle, providing you cover
    fire as you take the point. After she shoots down the ladder jump up
    to it and continue over the wall. Once you hop over there will be a
    few Zombies on your right and left and a Zombine. I ran to the next
    wall and just let them get into Alyx's sight and let her kill them.
    Continue on in to the doorway on your right, there will be some
    supplies on the right, as well as a Black Head Crab. Advance up the
    stairs until you come to a hall that has some boards on the left and
    there is a Zombie on the floor. Again, make use of Alyx's talent and
    knock all the boards you can off as quickly as possible and just
    retreat here and pull Zombies and Zombines back and conserve ammo.
    Once all the Zombies/Zombines are dead continue through the hall and
    down the steps gather supplies as you continue on out.
    Once back on the street you will here a Combine soldier killing the
    Ant Lions on your right. He is covered by some metal so Alyx can't
    get a clear shot, but just grab one of the metal sheets off with your
    Gravity Gun off and Alyx will kill him. After he is dead, cover the
    Ant Lion pit with the car and continue forward towards the gate. Now
    the Combine gate will open and close, again Alyx can do most the work
    here, once it opens just go for cover around a wall while she kills
    them, before the Gate closes run through...I don't believe it has a
    set amount of times that the soldiers will come since the two times
    I've played it is has seemed that the first time it was shorter then
    the second time. Once through Alyx will head your way and some Ant
    Lions will come off the roofs chasing her, just assist her to the
    gate and she will close it and you can continue onwards.
    Continue through the doorway that Alyx has opened for you. Go to the
    left doorway and kill the Combine soldiers in here, then continue
    into the central room. There will be some supplies in here, as well
    as some Pulse Rifles you can pick up. The doors will start beeping,
    this is the Combine's way of blowing the doors. What I will usually
    do is when it gets close to blowing, toss a grenade and you should
    time it good enough to kill the Combine coming in. Once they are all
    dead fill your life and suit up and continue through the left door
    and into the left doorway of where you came in. You will see an
    explosive barrel, explode it killing the Combine in here and then
    continue. Finally you will come to where a dead rebel is, collect the
    supplies up here and drop down.
    After dropping down you will see some Combine soldiers fighting some
    Ant Lions and an Ant Lion elite. Here I preferred to use the SMG
    because there is a SMG ammo case in the back so you will unlimited
    ammo. Just pump the Ant Lion elite full of ammo until it is dead,
    once so  quickly round the corner and cover up the two Ant Lion pits,
    after that is done, go back and collect any supplies you need. Once
    you are ready head back to Alyx, she should say something about the
    Combine being on the rooftops, man the gun and kill any Combine
    soldiers who come through the gate and that are on the roofs. Once
    they are dead go through the gate, there should be two more soldiers
    in a small ditch, but a rebel should come out and shoot a missile at
    them killing them, if not just kill them. Continue into the next room
    and you will see a lot of explosive barrels. Grab it so that you can
    see the Hopper. Grab the hopper and just place it aside. Then
    continue through the vent.
    In the vent you can go to your right and up the ladder and use the
    Gravity Gun to grab some energy packs, if you keep walking you will
    drop out of the vent back to where Alyx is. Get back in the vent and
    go left, before you continue forward and this vent will drop. Don't
    go out of either end because there are a ton of Trip-Mines and
    explosives. Instead you should be able to pop out of an exit out of
    the top of the vent. Hop over all the mines and into the elevator,
    the best way to do so is very carefully jump to the left side, crawl
    under the trip mine and then at the two connecting ones sprint jump
    over them into the elevator. The elevator will drop and be submerged,
    blast the top vent off so you can get out. Then clear out the bottom
    room, just pull a barrel into a Trip-Mine. In this room there will be
    a broken window with a Black Head Crab in it, kill it and jump in.
    Then climb into the new vent, use something to give you the height,
    the table or explosives drum works fine.
    Exit the vent and you can clear out this room to your left, it should
    ricochet some junk into the Barnacles giving you a clear jump to the
    right ledge. Continue on this ledge around to the ladder and climb
    up. Then you will see another vent to your right, drop down to it and
    enter it. Finally you will come to the end, drop the vent lid to
    activate the trip-mines and clear the room. Before dropping down pull
    up the two Hoppers closest to where you will drop, then drop down and
    pull up the last one. Turn on the electricity to let Alyx in, and
    then continue to door opposite of where Alyx came in.
    In here toss the explosive barrel to trip all the trip-mines and then
    kill the Zombie as well. There is a hopper in the corner, I would
    grab it and set it at the end of the stairs. Head towards the stairs
    and the door will do the beeping thing again, the Combine should come
    down and be killed by the Hopper. Once they are dead go into the room
    they came from. Grab the Crossbow and any other supplies in here and
    then find the plug for the security gate and unplug it and go through
    where the gate was and out onto the street. Just move forward killing
    any Combine that come out until it is all clear, once it is clear you
    should see a guy by a gate on the right side midway down the street
    (in a white shirt) walk towards him and Alyx should speak with him.
    After he asks you to follow him to safe house, do so, in the first
    room you can watch the speech Dr. Kliener gives, if not continue up
    the stairs. Eventually one of the missiles with Head Crabs in it will
    blast through the ceiling blocking your path, turn 180 degrees and go
    into the door with the wooden block blocking it. Continue forward and
    you will drop through the floor with multiple Zombies in it. After
    killing them, advance back to the stairwell and into the room where
    you dropped down. Avoid the busted flooring and go through the door
    on the left, in here will be a Zombine. Kill it and continue up,
    eventually you will come to a door and meet up with good ol' Barney.
    After speaking to Barney he will let down the bridge and give you
    your oh so adorable and awesome Crowbar. Cross the bridge and go
    across the next small walkway. Continue up the stairs and round the
    corner to find a couple of the Black Head Crabs, after killing them
    continue on and you will come to some Zombines. Once you kill them
    you will come to another bridge, knock the wooden block from the reel
    to let it fall down, then cross over and go in and to the left hall.
    Continuing through the hallway you will eventually come to one long
    hallway with a few Zombies and Combines. As you advance a Gunship
    will be shooting at you, so donít go into plain view stay low and near
    the wall. Continue advancing and eventually you will come to an end
    and some stairs leading into a new area, you guessed it, time to
    fight the gunship.
    Thereís a crate with rocket supplies, just get three clean shots on
    the gunship and you are good. Its best to wait until it starts firing
    at you so that you can get a clean shot on it instead of it firing at
    the rocket and diverting it. Once it is destroyed it will crash into
    the room, fill up on rockets and hop down to the door below. The door
    will start beeping and some Combine will come in, kill them and
    advance. Advancing down the hall you will come to a room, there is a
    Hopper behind the box, pull it up and toss it at the trip mines. Then
    go towards the security gate. Alyx will grab a Shotgun, then disable
    the gate, continue through this hall now.
    Its pretty straight forward, just kill any Combine and
    Zombies/Zombine that you come across and search the rooms for
    supplies. Eventually you will come to a dead end with one room on the
    right and one on the left, the one on the left has a Zombie in it
    knocking on the door. It will break the door then continue through
    the right room. In this hall there will be a bunch of Combine and
    Zombies, kill them off and watch out for a Hopper, thereís one on the
    left side somewhere. After this is clear, advance down the open
    hallway and there will be a set of double doors with a bunch of
    Zombies knocking on it, continue heading down though and you will
    come to a door where two Combine soldiers will be, kill them and then
    the Zombies will come out, there will be a Zombie Carrier throwing
    the Black Head Crabs at you, kill it and advance into this room.
    There will be a hole in the floor, drop down this hole.
    You will drop down another floor into some water, continue forward
    under some piping and other junk, once you surface walk up the
    walkway and shoot the Black Head Crab on your right then you will see
    a small hut like thing, inside is another Black Head Crab. Jump in
    here and then continue to the far left. Kill the barnacles with your
    Shotgun as you advance. Then you will see a blue barrel across from
    you, pull it with your Gravity Gun, put it under the far left walkway
    to keep it afloat. Then head back to the pillar, there is a switch on
    here, throw it. This will activate the electricity but you wonít be
    able to fall into the water. Sprint jump to the first ledge from the
    walkway. Then turn right and hop onto the pipes and then onto the
    small metal ledge to get into the hut like thing. Once in jump out
    and walk around to the now open blue door. Ascend the stairs and go
    out the door, Alyx will drop down and join you, now head into the
    room on the right of this hallway.
    In here will be a Zombie Carrier and a bunch of Head Crabs including
    the Quick ones. Dispose of them and then and be prepared for a wave
    of some more Zombines and Zombies. You can use the hoppers to your
    advantage here. Once everything is dead go to the right, in this hall
    there will be two turrets at the end and a bunch of hoppers. Advance
    slowly using the small area in the wall as protection, you cannot
    knock over the turrets so just advance, kill the Zombies, and
    eventually you will reach the end and you can pull the plug on the
    gate and the turrets will be deactivated. Advance now and go through
    the doors on the left and advance to Chapter 5.
    HL2-5-E Chapter 5: Exit 17
    Once the chapter starts go in the room to your left and grab some
    supplies. Head on out and meet up with Barney. He will explain that
    they need someone to escort the groups to the train station, that
    person will be you. You will be taking a group of 4 each time into
    the train station. Follow Barney and this is where you will start,
    once you get the first group, head directly across from the exit
    where Barney is. Once inside follow the hall into the rooms with the
    trains. In here the first time go down the small steps, to your left
    under both trains, then backwards up the small steps. Once in the
    hall continue down until you come to another Medic rebel. Thereís a
    .357 Magnum here that you can grab and you will part with the group.
    Now the main thing will be to rinse and repeat, it gets different
    each time though.
    Tim advised me on this level during the first run, there is no
    combine interference, which is true. So if you need to, this is the
    best time to gather ammo, health, and position stuff. He advised that
    he was able to move some explosive barrels and loose ammo near the
    exit or at other convenient locations. He was able to bring enough
    loose rockets to kill the Strider early in the Strider fight.
    Be advised if done so, another one will spawn to complete some of the
    Thanks for the info Tim.
    Head back out to the main yard, some Manhacks will come out and some
    scanners will drop a few hoppers. Just pull the hoppers up and place
    them pretty much anywhere. Go back to Barney and get your second
    group. Once you walk back out a few Combine will scale down the large
    building you came out at the start of the chapter. Kill them then
    head into the train area. A few Combine will come from the window
    above, kill them and continue to Alyx. Once they reach Alyx they are
    safe and she will cover them and kill any Combine she gets in her
    sights. Head back out to the main yard once again. After coming out
    there should be one sniper trying to hit you, its easiest to just use
    the RPG and hit the window he is in. Grab the third group.
    Run back out and some Combine soldiers will again scale the large
    building. Kill them and then head into the train yard. Once you enter
    the train yard an elite Combine will fire a special Pulse Rifle shell
    at the first train knocking it down as well as the walkway on the
    right. You now need to ascend the walkway on the right and go around
    and drop down to Alyx. Some Combine soldiers should come from the
    ceiling landing on the top of the second train. Kill them and hop
    down to escort them to Alyx. After doing so head back to the main
    yard. There will be some soldiers out here this time and once you
    actually walk out a Combine Armored Car will come out and launch some
    missiles at you. Just shoot it with 4 RPG's and it will be destroyed.
    Clear any remaining Combine soldiers and grab group # 4.
    As you grab group #4, again some Combine will descend the rooftops.
    After killing them, advance into the train room. This time there is a
    blinking door right across from you when you enter. Kill the Combine
    that come out and the continue up the walkway. Once they are safe, go
    back to the main area and grab the very last group. There will be 5
    or so Combine soldiers out here and they should release a couple of
    Manhacks. Kill them off and then a few should come from the large
    building. Once it is clear grab Barney and the last group.
    Again advance through the main yard killing the Combine who scale the
    large building. Then head into the train area, should be the same,
    but there should be an additional two Combine Elite on the second
    train, escort Barney and the last group to safety and go in and meet
    up with Alyx and Barney grabbing any other supplies you need. Follow
    Alyx into the train yard as she opens the gate and you part from
    Barney and then continue forward as Alyx bypasses the security gate.
    Alyx will say she will go ahead and start on the next train, open up
    the gate for her with the rusty wheel, once she passes through drop
    it and run for cover, a Strider will come into the area and so will
    some Combine soldiers. Yes you will get to kill the Strider!
    Once itís in the area head to your right, it should blast a whole in
    one of the containers, pass through it and as you round the left
    corner two Combine will drop behind you in the fenced in area, kill
    them and then continue forward into the fenced area. On the right
    there will be a half opened canister with one of the Head Crab
    missiles, go in there and out the other end going to the right once
    you get out. Go up the canister and into the open one on the left, an
    explosion will cause the two Head Crab missiles to open releasing two
    Black Head Crabs, kill them and continue on out. Go to your right and
    hop on the one canister that you walked up that was on an angle and
    then jump on top of another canister. From here you can see a ledge
    on the left, jump on it and use the walling for shielding from the
    Strider. If you have 3 RPG missiles hit the Strider with the missiles
    if you have them. Rounding the ledge safely, one Combine will come
    from the ceiling, kill it and continue and pick up the Hoppers and
    just drop them or take a shot at the Strider. Finally jump from the
    end of the ledge onto the floor behind a canister, move out from
    behind it because the Strider will push it to the wall to kill you if
    hide behind it, when you move out just drop on floor straight below.
    From here two Combine will come out, destroy the explosive barrels
    behind them to kill them and some more barrels will come down at you,
    punt them away with your Gravity Gun if they get too close. Continue
    forward moving fast and to the left between two train cars and then
    up the ladder. Finally you will get some RPG ammunition, use it to
    take out the Strider. It took me 6 missiles and 1 Hopper (unsure if
    the Hopper even damaged it, but I did get a clean shot on it). Once
    it is dead continue forward to the opposite end and down the ladder.
    Meet up with Alyx again and then hop on the train and you have beat
    Half Life 2 Episode 1, enjoy the ending and congratulations! Let the
    credits play through and it will play the Episode 2 preview (don't be
    fooled it should minimize and reopen and look like its doing the
    Valve intro, but it is the preview).
    HL2-6 Weapons
    Here are the listed Weapons, I will rate the damage from 1-5 as well
    as include a small profile, when it is acquired, the max clip size,
    ammo capacity and any secondary functions it has.
    Gravity Gun - The tool that was introduced in HL 2 that can do many
                  things. Acquired in Chapter 1, it is mainly used for
                  punting things and picking them up and moving them
                  around, can be used a weapon on some things, mainly
                  Head Crabs and Ant Lions but it does very minimal
                  damage. Damage 1 of 5.
    Reconfigured Gravity Gun - In Chapter 1 your Gravity Gun gets a
                               "boost" it will now let you use the pull
                               and punt actions as a killing tool every
                               hit is a 1 hit kill no matter what. Damage
                               5 of 5.
    Crowbar - The tool many love to use, you get this in Chapter 4, late
              in the game, but it is quite effective at killing things
              close range. It has a very high damage for an item that you
              would think wouldn't. Damage 3 of 5.
    Hand Gun - A standard Hand Gun, same from HL 2. You get this in
               Chapter 3, it is quite efficient at close range and can
               still do some damage at long range. Damage 2 of 5. Max
               Clip Size - 18, Ammo Capacity - 150.
    .357 Magnum - The old Smith & Wesson Magnum look alike, packs a punch
                  for small gun. Acquired in Chapter 5, not too much time
                  to get a lot of use out of it, but it does a ton of
                  damage for it's size. Damage 5 of 5. Max Clip Size - 6,
                  Ammo Capacity - 12.
    SMG (Sub Machine Gun) - The SMG is super common among the Combine,
                            but I don't like it too much since it's
                            efficiency goes down the farther the enemy is
                            away from you, but up close it works quite
                            nicely. Acquired in Chapter 4 really early
                            on. It's secondary function shoots a grenade
                            out which explodes upon impact, very nice for
                            eliminating small groups of enemies. Damage 2
                            of 5. Max Clip Size - 45, Ammo Capacity - 225
    Pulse Rifle - Another common gun among the Combine, it packs a punch
                  with its firepower, from up close or even from far away
                  it doesn't lose too much damage over distance. This is
                  also acquired in Chapter 4, about halfway through. The
                  secondary function is quite useful in smaller areas. It
                  shoots an energy ball that disintegrates most enemies
                  upon impact. Damage 4 of 5. Max Clip Size - 30, Ammo
                  Capacity - 60.
    Shotgun - The Shotgun is probably the most efficient weapon since
              most of your combat is up close. It does a lot of damage up
              close, can kill most things very quickly and it is quite
              common so ammo is plentiful. Acquired in Chapter 3 along
              with the Hand Gun. It's secondary function is really nice,
              it does 2x the damage for 2x the ammo, which can eliminate
              most enemies, or bring them down to low health. Damage 3 of
              5. Max Clip Size - 6, Ammo Capacity - 30.
    Crossbow - This is the "Sniper Rifle" of the Half Life series, and it
               is quite effective. It shoots out a metal arrow into the
               enemy, kill most enemies in one hit. It's secondary
               function is what makes it the Sniper Rifle weapon,
               allowing you to zoom in and get a good clean shot off.
               This is acquired in Chapter 4 about half way through or
               so. Damage 5 of 5. Max Clip Size - 1, Ammo Capacity - 10.
    Grenade - The grenade is a nice weapon to have when coming into areas
              with large groups since it does massive damage in the area
              it can wipe out groups of enemies at once. Itís secondary
              function can be useful when just needing a short throw, it
              does a light toss instead of a full throw like normal. I
              believe these first come up in Chapter 4 if I'm correct.
              Damage 4 of 5. Ammo Capacity - 5.
    RPG - The RPG is probably the best weapon since you can use it on
          most enemies killing on impact and because it can kill the
          enemy vehicles. A lot of times you will come across a limitless
          RPG crate when you will need to use it, so you can just use it
          on anything you need to kill. It is a controllable rocket which
          you control by pointing the laser. You acquire this firstly

    HL2-7 Enemies
    Here is a list of the enemies from Half Life 2 Episode 1. I believe
    all are the same from Half Life 2 other then the Zombine and Stalker.
    I also listed a difficulty rating and some small tips on what you
    should use to kill them.
    -Head Crabs-
    Head Crab - Basic enemy in HL2 Ep. 1, one of the most familiar
                enemies and easiest. They hop at you to attack, very easy
                to kill with one shot from most weapons and 2 from the
                Hand Gun. Difficulty 1 of 5
    Black Head Crab - Little more advanced then the Head Crab and it
                      contains a neurotoxin that will bring your HP down
                      drastically, your suit will recuperate the hp back
                      up, but during the time you can be easily killed.
                      Stronger weapons preferred on these enemies.
                      Difficulty 2 of 5.
    Quick Head Crabs - Not too many of these in this game, but they are
                       defined by their long legs, they are much harder
                       to hit and way more annoying due to their speed. I
                       suggest using the Shotgun or any Machine Gun on
                       them for quick removal. Difficulty 3 of 5.
    Zombies - These are normal civilians with Head Crabs who have made
              their home on, well, their head. They usually are slow and
              don't do much damage, but they can throw barrels and
              objects at you, which can hurt you. No real suggestion on
              weapons, just use what you have on them...obviously the
              stronger weapons will kill them off quicker, but any weapon
              really does the job. Difficulty 1 of 5.
    Zombie Leapers - These are the more rotted down Zombies with the
                     Quick Head Crabs on them, they are super fast and
                     they can leap and climb. They can get annoying in
                     packs but they aren't seen that often in HL2 Ep 1.
                     Make quick work of them with the Shotgun. Difficulty
                     3 of 5.
    Zombie Carrier - Self explanatory, carries the Black Head Crabs and
                     can be quite annoying because they can be thrown
                     long distances with superb accuracy, and a lot of
                     the time even if you blast the Zombie itself most of
                     the Black Head Crabs still live. I suggest using
                     Grenades on this guy, it will either kill off the
                     Black Head Crabs on it at the same time, or at least
                     hurt them. Difficulty 3 of 5.
    Zombine - The new addition to HL2 Ep. 1. Combine turned Zombie. These
              guys are tough, not too bright, but they do take quite an
              amount of bullets. A lot of the time they will pull out a
              grenade and run towards you, if you are trapped you can
              easily shoot the grenade with your Gravity Gun out of it's
              hand, or pull it out and toss it. Higher damaging weapons
              are much more effective. Difficulty 2 of 5.
    -Combine Soldiers-
    Standard Combine Soldier - These are the most common enemy in HL 2
                               Ep 1, black suit, white mask, have a
                               variety of weapons and aren't all too
                               tough. Shotgun at close range makes quick
                               work of them, at long range I would
                               suggest the Pulse Rifle on them or the
                               Crossbow, for large groups Grenades and
                               the RPG are best. Difficulty 1 of 5.
    Elite Combine Soldier - Identified by the all white suit, they are a
                            little more tough and commonly use the Pulse
                            Rifle and do have the capability of using the
                            special on the rifle so be aware. The same
                            killing method as the Standard Combine
                            Soldier is suggested, it will take a bit
                            longer, but still works none the less.
                            Difficulty 3 of 5.
    -Ant Lions-
    Ant Lions - These are the wicked green bug creatures. They can get
                quite annoying because of their numbers and that they can
                limitlessly respawn. One on one itís probably better to
                use your Machine Guns or Shotgun on them, but if you come
                across an Ant Lion pit, cover it quickly with a car or
                other large object to keep them from respawning.
                Difficulty 3 of 5.
    Ant Lion Elite - These are generally larger and tougher. They can
                     launch things at you with brute force and they
                     constantly charge at you to hit you. A general
                     strategy is to just pump as much ammo in it as you
                     can, preferably the SMG or the Pulse Rifle. You can
                     also stand near a wall and when they charge at you
                     move, they will slam into the wall and you can get
                     some free shots into them. Difficulty 4 of 5.
    -Mechanical Units-
    Hoppers - I wouldn't too much call these an enemy more then I would
              say itís your ally. These are mines that hop up when you
              step too close, once they have hopped up they will explode.
              Pull them out of the ground with your Gravity Gun and you
              will be able to either plant them for your own use, or toss
              them as an explosive. Difficulty 1 of 5.
    Turrets - Thereís only a few of these and they aren't too bad but they
              can get difficult. The most effective weapon is explosives,
              because you can't really destroy them other then by
              knocking them over, which does kill them. If you have a
              grenade or explosive barrel you can toss it at them, knock
              them over causing them to malfunction and no longer work.
              Difficulty 3 of 5.
    Scanners - I think they are only seen once or twice in Chapter 5,
               they fly overhead dropping Hoppers in the area. I'd
               actually say they can help a bit since you can pull the
               Hoppers up and use them to your advantage. You can't
               really kill them, at least I never got enough time to
               do so, but just beware of their Hopper dropping skills
               since they can drop them close to you and have them blow
               up soon after. Difficulty 0 of 5!
    Manhacks - These are the flying small mechanical units with a very
               sharp blade, I guess that signifies the name. Very easy
               to kill, just grab it with your Gravity Gun and toss it at
               the ground or a close wall and it should explode. If not,
               just repeat the process. Difficulty 1 of 5.
    Tondi advised me that another tip with the Manhacks is when tossing
    them you can hold them and toss them at a second enemy (combine
    soldier...etc) and take out the Manhack as well as the second enemy
    or at least do a nice ammount of damage without using any ammo.
    Thanks for the info Tondi
    Flashers - These don't real inflict any damage, but can be very
               annoying since they come in your face and flash you with
               a bright beam of light, temporarily blinding you which can
               suck if you are in the middle of a firefight. Just grab
               with your Gravity Gun and toss them like the Manhacks, or
               smack it with your Crowbar a few times. Difficulty 1 of 5.
    Roller Mines - These are the annoying little electrical balls that
                   roll towards you and attempt to shock you to hurt you.
                   In this game they have a bit more usefulness though,
                   since you can have Alyx reprogram them and you can use
                   them to fight for you. If you want to kill them just
                   toss them over some buildings or way far away, they
                   should explode. Difficulty 1 of 5.
    -Combine Attack Units-
    Gunship - This is the enemy helicopter like vehicle that flies around
              you and shoots its gun at you constantly. It isn't too
              tough, but it can be very annoying. Destroy it by shooting
              the RPG at it. Hit it with 3 missiles and it should be done
              for. Difficulty 3 of 5.
    Armored Car - Stationary Combine cars that launch missiles at you,
                  not too hard and you can generally avoid the missiles.
                  4 missiles from your RPG should bring it down.
                  Difficulty 2 of 5.
    Striders - This is probably the toughest enemy I've encountered.
               It's quick, has two main attacks, a pulse rifle attack
               and a stronger beam attack which can do heavy damage.
               They have a lot of health as well which makes them just
               as dangerous. The best way to kill these are to avoid
               their attacks as much as possible and pound missiles into
               them using your RPG, after 6 missiles or so it should
               collapse and die. Difficulty 5 of 5.
    Stalkers - These are also new to HL2 EP 1, they are basically the
               byproduct of what the Combine does to people who resist
               or are suspected of enemy activity. They are only seen
               in the very first two chapters but they have a weak laser
               beam attack from their eyes. Since at the time you have no
               real gun, you usually can just use an energy ball to kill
               them. Difficulty 1 of 5.
    Barnacles - Probably the easiest enemy since they don't move or
                really attack you other then by actually biting you when
                they grab you. They leave their tongues down to grab
                something and eat it when it is touched. A single Shotgun
                blast or a few bullets from most other weapons will kill
                them, but they are easily avoidable. Difficulty 1 of 5.
    Brad B. advised me that for the Barnacles if you're low on ammo, or
    just want to conserver you can let it catch you and then just whack
    it with the crowbar when you're close enough and it will kill it and
    drop you down.
    Thanks Brad B.

    HL2-9 Review
    Well I enjoyed the game a ton. It was shorted, but expected since it
    is only one of the trilogy. Very much worth the hard earned $20 I
    spent on it. The lighting especially made a big difference in this
    game. If you played Half Life 2 you will see that they used some new
    technology with the lighting and it greatly improves the quality of
    the game, at least in my opinion. I found that also a great thing
    that was in it was the music segments. They were pretty good, but I
    wish they would have had more, or at least increased the length of
    some of them. Overall itís well worth the money, the AI does work a
    little better from my perspective and leaves you on a great
    cliffhanger for Episode 2. It sounds like, from what I interpreted
    from Dr Kliener's speech, that the Combines crippling hold on the
    people had also disabled some genetic strand that kept them from
    reproducing. With the citadel exploding it would erase that and they
    could reproduce, also from the explosion of the citadel it sounds
    like the Combine may be put out of business since they will have
    little to no communication and their shear numbers will have been
    depleted. Just for reference if I had to rate it 1-10 it would
    probably be about a 9. Hope you enjoyed it as much as I did.
    HL2-10 Frequently Asked Questions // FAQ
    Q: I get to the end of level 1, where you have to board the elevator
       with Alyx and there's falling debris. I don't see any debris, but
       I keep crashing and dieing, what is the issue?
    A: This is common to downloaded bootlegs of HL2 Ep 1. I've had a few
       questions on this and each has been with the person having a
       bootlegged version of the game. Just buy the game.
