Mole rats are mutated rodents that are much larger than their pre-War cousins. They have survived as a species by burrowing underground where the soil protected them from direct nuclear explosions. However, they still were greatly mutated by the subsequent fallout, increasing their size as well as their viciousness. A few people in the wastes have even been known to train them and keep them as pets.
Mole rats range in size depending on the type being fought. They range in size from a cat up to a large dog and possibly bigger. They have a bald, pink appearance, with large front teeth and small eyes. They are highly territorial and will attack anything entering their territory. They are surprisingly fast and will attack with a jumping lunge. They have a complete immunity to the Scorched Plague, as learned during An Ounce of Prevention.
Mole rats will tunnel underground to avoid their enemy or close in to attack unseen, they will also retreat to a tunnel if the player character moves to an area that is inaccessible to them, such as on top of a car. This makes them highly difficult to keep track of in groups. This ability is shared with radscorpions. If the player uses a weapon dealing damage over time on a radscorpion or mole rat just as they burrow they can die underground and the corpse will be irretrievable.
Mole rats are common pests in the wasteland, but compared to many other enemies mole rats are generally weak. However, if allowed to swarm, they may become a problem since they have the ability to easily hide from the player character's sight and attack from behind.
The standard variation of the mole rat. This enemy can be easily killed with most weapons in-game, making them usually not dangerous. The exception is when a pack of them turns hostile and attack together.
A larger, more powerful type of mole rat that is often found with mole miner groups, the mole rat brood mother is significantly more resistant than her children. However, her attacks still only do minor damage to a well-armored player character.
These particular mole rats have absorbed massive amounts of radiation and consequently glow. The glowing mole rat produces radiation in a short perimeter around and benefits from radiation sources in the form of health regeneration.
