A Guide to the Weapons and Monsters of Doom 2 by Colin Glassey Since I spent the time to go through every level of Doom 2 I might as well write some of my observations down. There are books that go into more detail and have maps but, if you would rather not spend the money, you can read this instead. FYI: I played Doom 2 on a 486/66 w/16 MBytes of RAM at the Hurt Me Plenty Difficulty Level. 1) The chainsaw. This is useful when you are low on shotgun shells and there are some pink demons to kill. As long as you can avoid getting attacked from more than one direction, you should advance against the demon while running the chainsaw. The chainsaw does not seem to be as effective in this game as it was in Doom 1. The chainsaw can be used against the floating eye or flying skulls to good effect. In Doom 1 I used the chainsaw against the flying skulls, but in Doom 2 I tend to use the plasma rifle or the double barreled shotgun instead. 2) The pistol. This weapon is inferior in every way to the machine gun. Of course, in Death match games you end up using it a lot, but it still is a very poor weapon. 3) The shotgun. There are now two versions, single barrel and double barreled (switch between them by pressing 3). The shotgun is a great weapon and generally the one I use by default. One shot from the normal shotgun kills all humans (except for the machine gun dummies), and the brown demons. The shotgun can be used to kill things that you are close to but of which very little is visible (such as soldiers partially obscured by walls). The Doom program is not as smart as it could be in figuring out damage in this situation (as opposed to other weapons which it is very good at figuring). You can even use the shotgun to attack monsters that are at a different elevation from you. It takes a lot more shots to kill such monsters but it is better than not being able to hit them at all. The double barreled shotgun is best used when you are dealing with pink or invisible demons, the machine gunner, or the flying skulls, it can kill these monsters with just a single blast. Since the double barreled shotgun is slow to reload, it is best used when you can retreat some distance with the monsters following you. Apparently, the double barreled shotgun does three times the damage that the normal shotgun does. 4) The machine gun. This weapon has a number of features which make it very powerful: 1) It has unlimited range and its fire is instantaneous. This makes it the best weapon when you have some long distance shooting. It is superior in this way to the plasma rifle since the plasma bolts don't move all that fast. 2) It only takes two or three shots to kill a normal soldier, you can fire those shots with just one press of the fire key. 3) While most monsters are being shot, they can't do anything other than retreat (the exceptions are the demon lords and other big monsters). This means that if you have the bullets, you can shoot at a floating eye monster until it dies without taking any damage. You must keep the monster under fire continuously, if you miss or there are breaks, the monster will have time to get off a fire ball or two. 4) Bullets are very small and can be fired just past the edge of a wall or through very small openings. Bullets can be used from firing positions that other weapons can't fire from. The down side to the machine gun is that it goes through bullets very rapidly. Even with a backpack, the most bullets you can carry is 400. It usually takes me about 70 bullets to kill a floating eye. Obviously, when faced with four or more floating eyes, other weapons are needed. Even though you find lots of clips of bullets in Doom, these only hold five bullets so running out of bullets is a constant problem when you use the machine gun extensively. 5) The Rocket Launcher. To my mind this is the most powerful weapon in the game. You can fire rockets very rapidly one after the other (unlike the BFG). It does lots of damage in a fairly large area (only the BFG does more). However, there are several down sides to the launcher: the most important is that this is the one weapon you carry that can hurt you. If you launch a rocket and it explodes close to you, you will suffer lots of damage. I have been killed on several occasions when I panicked and launched a rocket that exploded right in front of me. Another problem is that the rocket is not very accurate and if you miss the target, the rocket will sail on by, not exploding until it hits a wall or something else. A further limitation on the use of the rocket launcher is that there are not many rockets lying around. There are fewer rockets than any other type of ammo in the game. I make sure to save my rockets for the worst monsters (the Cyber Demon, Demon Lords and big fat guys) and the worst situations. However, I do not use the Rocket Launcher against the flying skulls, or the skull spitter because they can move toward you so fast that you might fire the rocket and have it explode close to you. By the way: the rocket launcher is a great weapon for Death match games because it just takes a single hit (or a near miss) to kill another player. 6) The Plasma Rifle. In Doom 2 the Plasma rifle is a more useful weapon than in Doom 1. First, it is very powerful and can fire very rapidly. When you are faced with a large number of floating eyes or flying skulls or brown demons, the plasma rifle is an excellent weapon. The plasma rifle is good at short to medium ranges, but at longer ranges, the fact that the plasma bolts take some time to travel means the odds go up that you will miss your target (as opposed to bullets which hit as soon as they are fired). When attacking humans, you are better off using the machine gun because the plasma rifle is not any more effective against humans than bullets. The other advantage the plasma rifle has is that monsters hit by the plasma bolts are unable to do anything (the same behavior as when they are hit by bullets from the machine gun). It is still the case that the large monsters (like Demon Lords, Big Fat Guys, and Arch-Viles) can and will attack you even if you fire continuously at them. Note that auto-fire from the plasma rifle does use up cells very rapidly. A change in Doom 2 is that there are lots more energy cells around than before. Since you can carry 600 cells, and since each plasma bolt is (usually) more powerful than a bullet, the plasma rifle may be a better alternative than the machine gun in short range encounters. The plasma rifle seems to lose some strength as the bolt travels. This is yet another reason to use the plasma rifle only for short or medium ranges. I found the plasma rifle to be especially effective against the electric spiders and the flying skulls. When surrounded by monsters, spinning around with the plasma rifle blazing works better than any other weapon (even the BFG). 7) The BFG 9000. This weapon packs the biggest punch of any single attack in the game but it is still hard to use and so slow as to make it a poor choice for most encounters. If the BFG energy bolt actually hits the target you want killed, it will take a massive amount of damage. Otherwise, you are better off using rockets or the plasma rifle. Obviously when you have few rockets and lots of cells, this is a good weapon. On one level I managed to kill a Cyber Demon with just three (or 4) well-aimed shots from the BFG, but that was only possible because I was invulnerable and up against a wall so the pounding of the Cyber Demon's rockets didn't knock my aim off too much. Further experience has shown that the Arch-Vile is so dangerous that I almost always use the BFG to kill the Arch-Vile as soon as I find it. Just one well-aimed blast from the BFG at close range is usually enough to toast an Arch-Vile. The Arch-Vile is very hard to kill with other weapons because it moves so fast and takes so much damage. Another time when the BFG is the right weapon occurs when you are facing lots of enemies, since the BFG will damage every monster that is near the point of the explosion without doing any damage to you. In these situations it is better than the rocket launcher. I ended up using the BFG a fair number of times in the later levels (25 to 30). Doom 2 Monsters (in order of difficulty) (Yes I know they have different "official" names but if you don't understand what monsters I am talking about, too bad). Riflemen: weak, kill them with two or three bullets from the machine gun. Sergeants: a bit tougher, three or four bullets or a single shotgun blast. Brown Demons: If I can pick them off one at a time I use the shotgun. If there are two, the double barreled shotgun will usually get them both. If there are three to six, I use the machine gun or plasma rifle. If there are lots, I use the rocket launcher. Pink Demons: If just one, I use the chain saw. If there are several but I can get them one at a time by retreating I use the double barreled shotgun. Machine gun Dummies: Reasonably dangerous, trading machine gun fire with them gets you hurt so I use the double barreled shotgun (takes just one well aimed shot) or the plasma rifle. These guys have the distressing ability to shoot at you even when you can't shoot at them (example: level 16). Invisible Demons: I use the double barreled shotgun and shoot for where I think they are. I have spent a fair number of shells trying to kill these fellows. Floating Eyes: I use the double barreled shotgun at close range, at medium range I use the plasma rifle, at long range the machine gun or the rocket launcher. Few things are more fun than hitting one of these beasts at long range with a rocket and having the floater sputter to the ground, dead. Flying Skulls: Use the double barreled shotgun or the plasma rifle as they charge you at high speed. Floating Skull Spitter: Rapid fire from the plasma rifle is the best way to destroy this nasty thing. Continued fire from the plasma rifle also helps deal with the skulls that appear as a result of the death of this monster. Electric Spiders: A plasma rifle is very effective against these fellows. The machine gun will also work but not as well. Demon Lords: Use the rocket launcher while sidestepping his return fire. I have found that demon lords are not so dangerous. If you have the space available, you can dodge their green fire balls and blast them with shotguns till they die. Stay out of range of their hand attack though, it does lots of damage. Big Fat Guys: I always use rockets. I also keep near a wall or doorway so I can avoid his return fire. Given enough range and space, you can actually dodge their attacks just by moving back and forth. You did save before trying this didn't you? Skeletons: Use the rocket launcher or the plasma rifle. If you get close, you can kill them with the double barreled shotgun, their kick does some damage but it is not nearly as bad as their fire ball. Their heat seeking fire balls can be dodged, but you need good timing. The key is to stay next to a wall, let the fire balls get close, then quickly move to the right or left. Usually the fire balls will smash into the wall where you used to be because the fire ball can't make course corrections very rapidly. I have actually seen one case where I dodged a fire ball and it circled back and hit the skeleton that fired it! Too bad it does no damage in the skeletons (?). Arch-Vile: Get close and use the BFG on him as he is trying to burn you up. One good BFG shot should toast him, if not, well, you did remember to save the game didn't you? Considering how dangerous these monsters are, it is a good thing that there are not many Arch-Viles in the game. Mastermind Spider and Cyber Demon Lord: Lots and lots of rockets. Both of these can take massive amounts of punishment but the Cyber Demon Lord is far more dangerous with his rocket attack. The room in level 19 where these two both show up is a great deal of fun if you can get them to start shooting at each other. Doom Cheats: Iddkfa This key combination resets all of your ammo to the maximum allowed (less if you have never found a backpack). It also gives you all of the keys, and all of the weapons. It does not increase your health. Iddt This key combination is used while in map mode to change the map state. The first state is just like you found the computer map of the level. The second state shows all of the monsters and goodies that are on the level. It also shows the fireballs of the brown demons as they move across the map (and the other fireballs?). Iddqd This key combination puts you in "God" mode. While in "God" mode you cannot be damaged by anything. Playing in "God" mode is rather boring.
