Fat zombie

A fat zombie, in Doom 3 and its expansions, is a zombie that is obese, but behaves like most other zombies.

Appearance
Fat zombies come in three forms:
 * 1) Unarmed
 * 2) Faceless, open abdomen, unarmed
 * 3) Faceless, open abdomen, with wrench

Combat analysis
A fat zombie, like a regular zombie, moves towards the player until he is close enough to attack. However, he has more health and inflicts more damage than regular zombies. A fat zombie that is unarmed has two possible modes: walking and running. In walking mode, he is slower than a regular zombie. In running mode, he has his arms lifted in the air and is faster than a regular zombie. Because speed is the only technical difference between the two modes, he is more dangerous in running mode. A fat zombie with a wrench is not capable of running, but he has farther reach than the other two variations. In Doom 3: Resurrection of Evil, these zombies are fairly common.

Doom Resurrection
In Doom Resurrection the fat zombie has a special characteristic: if it reaches the player, it will latch on and begin biting them repeatedly. The zombie must then be shaken off literally by rocking the phone or tablet back and forth rapidly.

Trivia
The 1997 first-person shooter Blood featured obese zombie enemies called Bloated Butchers. The 2009 first-person shooter [[:wikipedia:Killing Floor|Killing Floor also featured a similar enemy known as the Bloat.
