“Look out, everybody, things are about to get awesome!”
Tunnel Rats are not very durable and as such will try to stay as far back from their enemies as possible, shooting at them with assault rifles while ducking and weaving away from enemy fire. In the case that an enemy gets too close, they will either leap at them or hit them with a claw swipe to knock them away. If there is any loot on the field, they will run over to it and pick it up. If left alone long enough after picking up loot, they will bury it and the loot will become unrecoverable.
- Tunnel Rats encountered in The Fridge are visually unique as they wear garbs in red and white while Tunnel Rats in other areas wear garbs which are in brown shades.
- In True Vault Hunter Mode they are renamed Cannibal Rat, and in Ultimate Vault Hunter Mode they are renamed Flesh-eating Rat
