Rat (Fallout)

Background
These range from your typical starving, disease-ridden wharf rats to a somewhat larger - and hungrier - mutant, Chihuahua-sized rat. For some reason they appear to have survived the atomic bombs of the Great War and continue to multiply. Even after the Great War, the people see them as vermin. Later, they are considered as easy prey, so people started to eat their meat. All rats run in packs, but they're not usually very dangerous.

Biology
The common rat hasn't been noticeably affected by the high levels of background radiation, unlike most creatures of the wasteland. They range from sizes five to ten inches in length, and are known to gnaw through everything from electrical cords to heel tendons.

Gameplay attributes
The rats are by far the weakest enemy the player character can encounter in their travels. Rats travel and live in large packs, and are usually encountered in large groups with mole rats or pig rats.

Rat
Rats are very diminutive rodents who pose only an incredibly minor threat to most player characters. They're small, they're fast, and they've got a mean streak.

Appearances
The rats appear in Fallout and Fallout 2.
