Chaingun

The Doom chaingun is a rapid-firing, multi-barrelled automatic weapon. It uses the same ammunition as the pistol.
 * 1) For skill 1 / skill 2+
 * 2) When dropped by enemy
 * 3) Without / with backpack

The chaingun's rapid rate of fire means that enemies caught in its hail of bullets will have little or no chance to retaliate. The weapon is also highly effective at mowing down hordes of zombies or imps.

The chaingun always fires at least two shots. The first two shots in a burst will always be exactly on target, but the weapon's recoil will cause later shots to wander rapidly off-target. This makes the chaingun an ideal weapon for sniping, as you can simply tap the fire button for accurate two-shot bursts ("Remember: short, controlled bursts" &mdash; Corporal Hicks, in Aliens).

The chaingun contains 20 rounds of ammunition when picked up (40 on the I'm Too Young To Die skill level). Chainguns taken from dead zombie chaingunners contain 10 rounds.
