In the DOOM RPG two classes of zombies exist, each with three variants corresponding to their difficulties.

The Former Commando does not appear in DOOM 64. The only real physical difference is that the Sergeant's pants are a slightly darker shade than the Former Humans (which makes them harder to discern within DOOM 64's darkness). In DOOM 64 there are no real changes in behavioural patterns amongst the zombies they simply walk and shoot. They also emit a 'sour lemon smell' when killed or nearby. However the former commandos depicted there (referred to as Clyde) are not zombiefied humans, rather they are either genetically engineered human copies or human traitors who have been genetically altered to look alike. In the DOOM novels, zombies are found in various forms, ranging from former civilians to soldiers. (Appears in DOOM II, Final DOOM and the PlayStation and Saturn versions of DOOM) Also known as heavy weapons dude or chaingunner.

Former commando: 70 HP, wields a chaingun that he will drop when killed.

(Appear in DOOM, DOOM II, DOOM 64 and Final DOOM)

Former human sergeant: 30 HP, wields a shotgun that he will drop when killed.

(Appears in DOOM, DOOM II, DOOM 64 and Final DOOM)

Former human: 20 HP, wields a rifle, will drop an ammo clip when killed.

Three different forms of zombies are featured in the DOOM video games: Moving out of their line of sight, such as hiding behind a wall or using a lift, will break their lock and cease their firing, and they will be on the move to seek out their foe. Commandos, however, once within line of sight of their foe, will continuously fire their chaingun, only rotating to adjust to their target's movements.

(The dropped ammunition, however, can be lost if a door or crushing ceiling comes down on it.) Owing to their usage of bullet weapons, zombies can be easily tricked into engaging in monster infighting with other creatures as well as their own kind.įormer humans and sergeants will close the distance on their foe, and then circle, pausing every few steps to fire a shot. They are the only non-demonic enemies in the game as well as the only ones who drop ammunition (half the ammo of a fresh clip or a weapon pick-up) when killed. Zombies are undead soldiers who have been turned into brain-dead killing machines by the demons.
