Mole rat

This set of rodents just love to sink their teeth into your flesh. They vary greatly in strength — at the low end, you’ll find the rat very easy to defeat, while at the high end, the mole rat can pose a real threat. While the giant mole rats found on the West Coast are mostly covered with fur, the ones from the East Coast are not, possibly being mutations of different species.

Mole rats can often be found in packs together with pigrats and giant rats.

A rare variety of intelligent, albino mole rats exists. The only two known specimens are Keeng Ra'at and Brain.

Immediate Attacks
Specifically in Fallout 3, other than the Radroach, the Mole Rat will most likely be the first creature that you encounter, and also the easiest to kill. Because Molerats are so easy to kill they should instead be hit to death with melee weapons. (Sledgehammers work the best becuase of their stopping power). Another good option, due to its lethality to Molerats, is the Repellent Stick, which makes fighting Mole Rats at low levels a breeze.

Appearances
Mole Rats appear in Fallout, Fallout 2 and Fallout 3.
