Doom 3 Quick Weapons and Enemy Guide This guide was written by Wing L. Mui (email@example.com, http://www.wingie.org) on 8/7/2004. It was written mostly because the Doom 3 section of GameFAQs (http://www.gamefaqs.com) site was quite empty and he had some time on his hands. This is not meant to be the definitive FAQ nor is it a walkthrough (this game is quite linear, and most of the time there's only one path anyway, so unless you're looking for secrets you don't really need a walkthrough) of the game. Also, he is not affiliated with id Software in any way. This document is (c) Wing L. Mui, 2004. Doom 3 and everything related to it is (c) id Software.

Keep in mind that all these numbers are from the default difficulty setting of the game. They may (and probably will) change depending on which level of difficulty you play. I have only played through the normal (Marine) difficulty. ---------------------- Weapons 1 - Fists. Melee weapon, doesn't consume ammo, but is quite slow and useless. Don't use this unless you absolutely have to. There are times in the game when you get "possessed" and you cannot use anything but your fists. While the "possession" is in effect you're invincible and your fists do incredible damage! Run around and punch as many enemies as you can before it runs out! 2 - Pistol. Ranged weapon with a capacity of 12 bullets. I think you can hold up to 360 bullets at once, though by the time you get this many bullets you'll most likely have bigger and better guns. It fires rather fast and is good for short and mid-range fights, but it takes a while to reload. 3 - Shotgun. My favorite weapon in the game. Ranged weapon with a capacity of 8 shells. I'm not actually sure how many shells you can hold as I never maxed out (told you it was my favorite weapon) but I would assume that it's over 120, as I had that many at one point. Each pack of shells gives you eight, while enemies frop four shells. Very powerful at point blank, but its power decreases rapidly with distance. The shotgun also takes the longest to reload--assuming you're reloading an empty shotgun as the shotgun is the only weapon that has a variable reload time depending on how empty it is--and has a rather long cool-down period between shots. Don't count on rapid- firing it. But it is very handy early and mid-game when you can't afford to waste ammo, and in Hell. 4 - Machine Gun. Ranged weapon with a capacity of 60 bullets. It takes clips as ammo and you can hold up to 600 bullets. Each clip gives you 30 shots while enemies drop 10 per clip. As the name suggests, it fires rather rapidly, and is good for all ranges--though it doesn't go too far. The best long-range weapon in early game. It's reload time is average. 5 - Chain Gun. Ranged weapon with a capacity of 60 bullets. You can hold up to 600 bullets. Each ammo belt gives you 60 bullets while enemies drop 30 per belt. Very powerful rapid-fire weapon. You even get a video disc describing how powerful it is! =) It's all for any distance though I find it better at mid- and long range. It fires very rapidly, and hits slightly harder than the machine gun, but takes slightly shorter to reload. You won't find much chain gun ammo in the beginning and the best use of the chain gun is to just hold the fire button, so it's not that useful until midgame. Warning: it takes a split-second before the chain gun spins up and fires when you press the fire button, so don't let go after you click! 6 - Hand Grenades. You can hold 50 of these explosive grenades. Each pack you grab gives you 5 more. They pack a serious punch but do not use them in melee, as they denonate upon impact with the enemy (not with walls though) and if you get caught in the explosion you'll take a lot of damage. They also bounce off walls and their explosions detonate barrels of explosives, so beware. You can throw these a bit faster than you can fire the shotgun, and there's no reloading. 7 - Plasma Gun. Ranged weapon that can hold 50 charged. You can carry up to 500 charges total, and they come in cells that give you 25 charges each (though some cells look bigger and has two blue glowing humps and they count as two cells). Fires a bit slower than the machine gun but still rather rapidly, and the reload time is around the same as the machine gun's. It does heavier damage than both the machine and chain gun though. It also has very good range. Beware that the plasma bolts are rather large and may not get through small holes, tights corners, in between railingsm etc. unless you aim carefully. Also, the plasma bolts don't travel as fast as bullets. 8 - Rocket Launcher. Ranged weapon that can hold 5 rockets, 96 total. Each rocket pack you get gives you 5 rockets. This is the most powerful "normal" weapon in the game. It fires pretty quickly but only holds five shots. Upon hitting anything the rocket explodes, dealing damage to everything around it. Therefore, do not ever use it in melee! Reloading isn't that slow, suprisingly. 9 - BFG 9000. The ultimate ranged weapon! It holds 4 charges and you can carry 32 of them. Charges come in the form of this green cube that looks like a gelatinous cube, with 4 charges in each cube. Essentially the gun fires a semi-homing giant green glob of energy. The glob fries every enemy around it with radiation as it travels, and then explodes when it hits the target. As the video disc in the game said, everything around it probably won't survive. You can also hold the fire button before releasing it to charge the gun up so it does more damage--you can look at the charge status on the gun's display itself. However, charging up the gun uses more ammo and if you charge it beyond level 4 it'll overload and kill you. 0 - Chainsaw. The ultimate melee weapon! Just hold down the fire button and point it at what you want dead. They will die very, very soon. It is the most powerful weapon in the game. However, its range is about one foot... Consumes no ammo, and very noisy even when you're not activating it, so it may mask sounds of approaching enemy. Q - The Soulcube. The best weapon in the game! The Soulcube consumes no ammo, but needs to be charged by killing five demons (any five demons) using other weapons before it can be used. Each time you charge it, you can use it once. When the cube is charged, a symbol next to your ammo display will light up and the cube will whisper "use us...". You can then press Q, fire to release the cube, and once the cube is out of your hands it will switch back to your previous weapon. The cube acts like a boomerang: it will fly towards the target (unless it hits a wall or something), hitting everything in the way and a bit beyond, and then fly back. It will destroy any non- boss enemy on contact and also drains their life! With the exception of the smaller demons (like the Trites/spiders) everything (including Imps) will give you all your life back. Very handy. Chainsaw vs. Shotgun: Why would you want to use the shotgun when you have the chainsaw? While the chainsaw is powerful, it takes a second or two before you saw that demon in half. In that second, it can hit you for some damage. However, with the shotgun at that range, the demon will instantly die leaving only its ashes and the smell of brimstone in your path. ---------------------- Enemies Zombies These are slow-moving civilians who got turned into zombies. Their only attack is whacking you. Do not underestimate them! They sometimes ambush you and their hits hurt! Some of them wield things such as wrenches and hit for 9 damage even when you have armor on. Try to kill them from a distance, until you have the chainsaw. They will die after 6 hits from the pistol or 1 point blank shotgun shot. Later on in the game, use the pistol or chainsaw for these guys so you can save precious ammo for your better guns. (It takes four to five plasma bolts to kill these guys!) Shotgun Zombies As the name implies, they are zombies with shotguns. Try not to fight them in close range. If you do, 2 shotgun shells will definitely do the trick--though it will probably give it a chance to shoot at you for about 5 damage. It takes about 6 to 10 pistol shots to kill these guys. Once you get a machine gun (8 to 12 bullets per zombie) they should be no problem. Machine Gun Zombies. Zombies, with machine guns. They actually look for cover and try to hit you from a distance, so I guess their brains weren't completely eaten after all. Shooting them with the pistol or machine gun while they're reloading would do the trick, if you have something to hide behind. Two shotgun shells at close range would also work. If you have to, a rocket or grenade would also kill one of these in a pinch. Imps You'll see a lot of these in the game. They can hurl fireballs at you or jump and claw at you. The fireballs do 7 damage and the slashes 4 each. The best way to take these down is 1 shotgun blast at very close range, running up to it while it's charging its fireball so it doesn't have time to claw you. 2 or 3 at short range while strafing their fireballs also works, but that wastes precious shells. A shotgun shell directly at one jumping at you will stop it short, though that is hard to pull off. If you have the space, take them out before they jump at you. They take about 13 bullets or 8 plasma bolts to kill. As usual, one explosion will take them out as well. If it does get within melee range, the only way to deal with them is to back up and shoot them and hope they die before they claw you again. =) A note: their fireballs are being thrown at you, literally. That means that they travel in a parabolic arc, so sometimes overhead structures can protect you from them. Pinky (Giant Dogs) They are very, very mean at close range, though they have no ranged weapons. If you're cruel, jump on a crate and rain death upon them. Otherwise try to back up while firing at it. They can actually take a direct hit from a grenade or a rocket without dying, and by the time your shot was fired they'll be too close for the next one. Pumping lead into them while walking back does the trick. 20 to 40 bullets, 20 to 30 plasma bolts, or 4 shotgun shells will take one out. You can kill one with 2 shotgun shells if it's very close, or if you fire your second shot right when it gets next to you, but that can be risky. Chainsaw works well too, but you'll take some damage unless you're running back at the exact same speed as it and it's just repeatedly running into your chainsaw. Maggot (Two-Headed Demon) They are melee fighters--Imps without fireballs, really. Shotgun works very well if you can't pick them off at a distance. Deal with them the same way you'd deal with an Imp. Sometimes they actually teleport short distances, though that's a good thing. Simply pull out your shotgun, wait at the red glowing portal where it is materializing, and shoot its head with the barrel one inch away from it while it materializes. Instant dead demon. =) Trites (Spiders) When you see little small slots 1/2 or 1/3 the size of one you can crawl in on the ground, know that Trites will come out of them sooner or later. At the distance, they are harmless and the best way to take them out is with the pistol (to conserve ammo) and the machine gun. 2 bullets or 2 plasma bolts or 1 of everything else kills a Trite instantly. At mid- and close range, the shotgun works well (kills one or even two with one shell) but since it reloads slowly you may get swarmed. Switch to another weapon instead of reloading if you can if one or more Trites are close by and you're out of ammo. When you need to take them out fast (outside Monorail Bridge, for example), a grenade will kill a whole bunch at once. They are very good for charging up your Soulcube. =) If they get close, shotgun them or just spray them with bullets. They do 7 damage per swipe and if you're swarmed it is deadly. Lost Soul (Flaming Skull) Same thing as Trites, except they fly. When you're in an open area in mid-game, beware of them. Machine/Chain gun and the plasma gun work well on these since they so try to dodge your shots. 2 or 3 of anything will kill them, 1 if you're using the shotgun when they're close. Cacodemon (Giant Sphere) They are giant floating spheres and can spit giant plasma bolts from their mouthes. The blots do 7 damage, but their splash radius is slightly bigger than the Imps' fireball's. The best way to deal with them is a rapid-fire weapon, as your bullets will shoot down the plasma bolts as well! At close range, the shotgun works very well (2 to 4 shells, depending on distance) and so does the chainsaw. The rocket launcher can kill them in one direct hit, but since they fly getting a direct hit at long range is hard. Cherub (Babies From Hell) They are essentially like Trites, except tougher, faster and hits harder. Take them out at long range, as only a very direct and close- up shotgun hit will kill it, so using the shotgun may give it a chance to hit you. Revenants (Skeletons with Rockets) The infamous skeletons with shoulder-mounted rockets! The easy way to kill these is with the plasma gun. Just aim slightly below its head and the stream of plasma will actually destroy the rockets as they come out! 20 to 30 plasma bolts will bring one of them down easily. Doing the same trick with the machine/chain gun doesn't work as well, but if you have no plasma gun ammo, that would have to do. Try to aim for the rockets when they are launched, and you can probably take one down before it hits you. They take 2 rockets to kill, and since there are more cells than rockets, use the plasma gun instead. In a pinch, 2 short range shotgun shells or even the chainsaw works wonders on them--if you can dodge the rockets. Oh yes, the rockets are homing rockets, so hiding behind crates don't work... Hellknight (Giant Demon with Blue Fireballs) They're like Imps, except much, much, much more dangerous. With a direct hit of their fireball it deals about 30 damage (and that's if you have armor!) and the splash radius of the fireball is quite large. They also swipe you for a lot of damage close up. If there's a lot of space around, fight them mid- to long range with the rocket launcher (4 rockets will kill them), the plasma/chain gun (a lot of bullets/cells), or the BFG (charge up to level 3, or it won't kill him in one hit!). Using the pistol or fighting close range is not recommended. The first time you meet these guys is in Hell. Save your chain gun and rocket ammo for these guys the first time you're in Hell! Once you get the Soulcube, however, you can kill them with one hit from the Soulcube. Fat Demon There is probably a better name for it, but if there is one I don't know it. They hurl plasma balls (as powerful as the Hellknight's) at you and they do it pretty fast. The same strategy for fighting the Hellknight applies to these. Rockets seem to work very well, as 3 will kill one. I have not actually gotten close to one of these yet, so I don't know how well the shotgun and the chainsaw work against them. They (or something like them) also appear in the Monorail Bridge area as a mini-boss along with some Trites. The chain gun works well there, as you don't have anything better (a round of chain gun ammo should kill one). The advantage you have then is that you have a lot of pillers to hide behind, unlike when you meet them in Hell. ---------------------- Bosses Vagary (Giant Spider) You first meet her in the Alpha Labs. She attacks by telekenetically throwing metal balls at you and by swiping you. Granade her as much as possible at the beginning, and then keep pumping her with lead using your machine gun. There's not much to hide behind in the battlefield and not much in terms of supplies, but she's not that tough. Later on you meet a few of her in the end of the Caverns. They'll be travelling with some Trites. So all you have to do is Soulcube them back to Hell. =) If you run out of cannon fodder to charge your cube with, just rocket them. The only reason she was tough in the beginning is because you didn't have heavy weapons. Guardian, Guardian Seeker You'll actually hear him referred to as "Guardian", so no description needed. =) You meet him at the end of Hell, and he guards the Soulcube. Make sure you have the rocket launcher from Hell, otherwise it'll be a tough fight. He has two attacks: an eight-way fireball spread (easier to dodge when you're far away) and a swipe (which does quite a lot of damage). There are also several seekers (demons with searchlights) hovering around. The only way to damage the Guardian is to kill the seekers, and then a blue light will appear above the guardian. Shoot the blue light and the Guardian will be damaged. After a few seconds the blue light will fade as more seeks will appear. Just repeat the sequence until it dies. The seekers are annoying because they fly. The chain/plasma guns work well against them, as is the rocket launcher (which kills one in 1 hit) but the best way to deal with them is to use the shotgun. 2 shotgun shells (1 if you wait until they drop down a bit first) will kill one of them. Rockets are the best way to damage the Guardian-- other guns too, in a pinch, but forget about melee--and about 10 rockets will kill the Guardian. Make sure your launcher is reloaded before you kill the last seeker! And keep moving. If the Guardian gets too close you're as good as dead. Also, there are some rockets lying around the area if you run out. If you haven't noticed yet, you get unlimited stamina in Hell. So don't walk, run. Cyberdemon (Tank) In the CPU core you will find the Cyberdemon, which seems to be what became of the Sarge. When you found the NPC who lost his BFG-9000 and a video disc telling you how the BFG can be defeated, you knew that you were going to have to fight a demon with the BFG. Yes, the Cyberdemon indeed is equipped with the BFG and also a swipe attack. A direct hit from the BFG will kill you, as it should, so be careful. The room has four pillers. They will sometimes be eletrified and touching them when will shock you for quite a lot of damage. As if that's not enough, the room is a giant platform, which means that you can fall off the edges! Luckily, there are items lysing around. To the left is a chamber with some armor, and to the right is a chamber with some med kits. Be careful, though, as the chamber doors open slowly. There are also a med kit and two cells behind the pillers, though they are between the pillers and the ledge, so getting them in the heat of combat could be dangerous. The BFG, as mentioned before, will fry everything in the room that the green plasma ball as line of sight to slowly, and then detonate when it hits a wall or you. The detonation will kill you instantly, and the radiation will hit you for 2 damage every second (more if you have no armor). The only way to stop it is to hit the green ball with anything--even splash damage from rockets would work. There are three ways to kill this guy. The first is the cheapest method. Equip your rocket launcher and fire at the middle of the demon as soon as the garage door opens, and one of your five shots will destroy its initial BFG shot. Then switch to the chainsaw and chainsaw it until it dies. If you have full health and armor, it should die before you do--and will leave you relatively unharmed, as it does not fire the BFG when you're too close. The second way is to run around, shoot the BFG shots, and shoot the Cyberdemon when you can. You have to be very, very careful of the pillers and the ledges if you do this. And keep moving, so even if you miss the BFG won't hit you. The plasma gun is the best at this as the plasma bolts are very good at hitting the BFG shots. The third way involves staying in one of the item alcoves and sniping the BFG shots as well as the demon. This is the trickest method but if your aim is good it will work--but it'll take a long time. In either case, stuck reloading while a giant glob of green plasma is heading your way is a bad idea. Sabaoth The final boss! This demon is a giant demon equipped with a rocket launcher. Luckily, the rockets are not homing. The battlefield is a circular ring. Falling off the inside or outside will lead you to a quick lava-filled death. Don't do that. Imps will climb into the battlefield from the middle of the ring. That's a very good thing as you need them to recharge your Soulcube, the only weapon that can damage the final boss. There are also some armor and a small amount of ammo lying around. Note that the boss can only be harmed by the Soulcube. This fight is actually quite easy, as long as you keep moving and don't fall off. Keep killing Imps (you can even shotgun them while they're climbing!) until your Soulcube is charged, press Q, locate Sabaoth, aim at its chest so no Imps are in your path, fire, and then run (luckily(?), you're in Hell, so you can run as much as you want) away. Thanks to the fact that the Soulcube is a boomerang it returns to you automatically. You want to be at least 1/3 the ring away from him at all times, which isn't hard to do actually. The real problem here are the Imps. You're likely to face several of them at once and while they don't do much damage individually they are quite annoying as a pack, especially when they get close. You also want to keep moving so Sabaoth doesn't hit you. The shotgun is too slow for this, and the machine gun not powerful enough. Use the chain or plasma gun--although the rocket launcher can kill Imps with one hit it doesn't do you any good when the Imps move in too close-- to kill the Imps. If you keep moving while you do this their fireballs shouldn't hit you. What I did and think is the best method is to just use the chainsaw for the Imps. The health you lose from the Imps is trivial compared to what you get back from the Soulcube. Just keep moving (kind of like circle-strafing except you're in close range) and you'll be fine. In fact, the only time I died in this fight was when I fell off a ledge. =) ---------------------- If you have any questions, e-mail me at firstname.lastname@example.org. I don't promise to answer them, but I'll try.
