Fat zombie

A fat zombie 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.
