Naughty Dog unveiled a new trailer for The Last of Us during their panel at Comic-Con this weekend, introducing a new character that will help protagonists Ellie and Joel on their journey west. Bill is a crazy, old lone wolf who the pair run into when they break into his booby-trapped safe house.

The cutscene suggests that Bill and Joel have some history, though their relationship seems complicated, to say the least. Apparently Bill is a mechanic, and Joel convinces him to help build the duo a car if they can find the necessary parts.

The Last of Us will come to PS3 in 2013.
