Arkham City Pre-Order Features Robin
According to a post on Best Buy, Robin will be available as a pre-order for Batman: Arkham City.
The post has the Boy Wonder touted as a character for two challenge maps for the game on PS3, PC and 360. WB hasn’t released an official word on this, so we just have the Best Buy listing to go off of.
Arkham Asylum had a similar pre-order, which featured the Joker being a character for challenge maps on the PS3.
