Monolith and Warner Bros have announced that the shooter Gotham City Impostors will be released during the "winter of 2012," which should put its release early in the year - presumably during January or February (and not December).
In it you'll take on the role of a wannabe superhero or villain and take the fight to the streets of Gotham City. The release date goes for both Playstation 3 and Xbox 360 and is, as previously reported, a download only release.
