Sorry if this has been suggested before, but with the newish skins available it has made me think of hacking fallout tactics to be able to play as a deathclaw. You could do any race that had recruits by moving them into the prefab character positions, starting a new game, and modifying the prefab character.
One of the things about being these races is they had different caps on SPECIAL.
Like deathclaws could get up to 12 strength and endurance and some other stats were capped lower. Mutants and ghouls couldn't wear normal armor.
I don't think this matches up with the deathclaw companion from fallout 2 though. It's been a while.
I don't think rolling a melee character with the deathclaw skin would get me very far and I want to do it! Must... RP....
