The Rat Caves are a place underneath Klamath. This is the source of the rodent scourge. Citizens have lived in the buildings above, and perhaps inside the caves, but were killed by the invading mole rats. The rodents are commanded by Keeng Ra'at.
- A 10mm pistol on a corpse just before Keeng Ra'at's chamber.
- 24 10mm JHP in a desk on the first floor.
- A combat knife hidden in the pile of bones in Keeng Ra'at's chamber. It is lying on the ground amongst the bones, somewhat hard to spot.
The Rat Caves appear only in Fallout 2.
