It seems that some PS3 users are running into trouble with Gotham City Impostors, and we're not referring to all the fake Batmen clogging the streets. According to posts on the Gotham City Impostors forums, some PS3 users are unable to unlock the full version of the game. Even after paying for the title, some find themselves stuck with the trial version.

A forum administrator notes that Warner Bros. is working on the issue with Sony and asks that users experiencing the problem respond to this thread with their PSN ID and the country from which they are playing. In the meantime, if you haven't already purchased Gotham City Impostors, we'd recommend waiting until the issue is resolved.
