Comic-Con 2011 is just about to kick off, but the previews last night are already paying dividends in the form of a release window and pricing details for Gotham City Imposters.  Yes, it’s that wacky almost-but-not-quite Batman shooter which pits super hero wannabes against each other in team-based death matches.  It will launch in the winter of 2012 and will cost 1200 Microsoft Points on Xbox 360 and $15 on the PlayStation Network.  Watch the trailer and if the gameplay is half as good as the comedic value, then Gotham City Imposters could be a title to keep your eyes on.
