Mutant crocodile

Bipedal, mutated crocodiles or alligators were going to feature in the cancelled Fallout Tactics 2, taking place in Florida. Nothing is known about them except for a few concept arts by Tariq Raheem. In one of them, the creature is apparently wearing clothing, indicating at least some of them being a sentient race.

The crocdiles might also be in Fallout 3's DLC Point Look which will take place in a swamp.
