Gotham City Impostors is not revolutionary by any means. But it is a whole heap of fun. It is a multiplayer game that wouldn’t fit in with any current Batman game on the market while not being robust enough to be its own full retail release. This is a prime example of what a downloadable title should be, however. It is a fun idea packed with insane humor and something you should definitely download if you’re looking for a change of pace from the more serious FPS offerings out there.
