Weapon

Doom/Ultimate Doom

 * Fists - No ammo? No problem!  Use your unlimited physical strength! Especially good with the berserk pack.
 * Chainsaw - Who needs to punch when you can saw demons apart with a spinning blade of fury?
 * Pistol - Your default long-range weapon. Try to find a replacement ASAP.
 * Shotgun - Good for general close range combat. Has a slightly longer than usual reload time.
 * Chaingun - Very good for ripping through hordes of demons. However uses up a lot of ammo, so use wisely.
 * Rocket launcher - Shoots explosive rockets. Great for gibbing large, close groups of demons, but also can hurt you if you're not careful.
 * Plasma gun - Shoots pulses of blue-hot plasma at high speed which can take down crowds of incoming enemies easily, if you know what you're doing.
 * BFG 9000 - The big gun. Get it and see for yourself!

Doom II/Final Doom
