Zombie (monster)

Zombies come in differently-colored clothes, unlike the original Former Human soldiers, but have other minor characteristics in common with the classic enemies, such as one zombie type having withered hair (compared to the classic Former Human's green hair). The basic Zombies in Doom 3 do not carry firearms like the Z-Secs, though a few may use wrenches and flashlights as clubs.

They generally come in a number of flavours, each with different heads (or even, occasionally, no head) and different damage skins.

Types
Distinct types of zombies are listed here:

Regular zombies

 * Zombie Scientist: Wears a greenish or blue lab coat. Can appear jawless, headless and faceless.
 * Zombie Maintenance Worker: Wears a brown-orange suit. Can appear jawless, headless and faceless. May carry a wrench or a flashlight.
 * Zombie Marine: Unarmed, wears a blood-stained, olive-colored tank top without armor. The rarest variant of the standard zombie.
 * Zombie Civilian: Wears a blackish coat/suit.

Special zombies

 * Fat Zombie: Obese, barefoot civilian wearing grey clothes. Can appear faceless and with an open stomach. May carry a wrench. Has roughly twice as much health as a regular zombie, due to the fat on the stomach absorbing bullets.
 * Fast Zombie: wears open shirts and shambles at a noticeably higher speed than normal zombies.
 * Flaming Zombie: affectionately monikered "Bernie", this burning zombie is noticeably faster than normal.

Unique zombies

 * Morgue Zombie: a reanimated corpse in the morgue. Looks like the boney zombies but wears a pair of underwear and sports a normal skin color. Only one appears in the entire game. Unlike regular zombies, he runs instead of walking or shambling, making him quite fast, however, he can be easily killed.
 * Chainsaw Zombie: also known as "Sawyer", a unique zombie type with a muscular appearance. Wears the remains of a maintenance suit with armored knee pads, has significantly higher than normal health, and armed with a Chainsaw. Humorously, one of these zombies in Delta Labs Sector 4 is seen wearing a party hat.
 * Boney Zombie: naked human, acts similar to regular zombies. There is two variations of this zombie type - hellish and regular. Hellish variant appears only in the Hell levels of Doom 3 (not present in BFG Edition version of the game) and BFG Edition-exclusive expansion The Lost Mission. Regular variant appears only in Resurrection Of Evil.

All zombies but the last four are very quiet, save the moaning (and the Chainsaw Zombie's trademark weapon).
