Warner Brothers has released a new trailer for the upcoming Batman inspired multiplayer shooter, Gotham City Impostors. The above trailer explains why citizens are taking up arms in the fight against crime (or joining in if you side with The Joker’s army) and shows off gameplay footage of the many weapons and tactics players will be using in the game. In other news, an open beta will soon be debuting on Xbox Live for anyone who heads over to the game’s website and signs up. This is your chance to get your hands on the game early, so don’t waste time and go sign up to participate! Put your crime fighting boots (or your Joker make up) on quick as Gotham City Impostors will hit Xbox Live Arcade early next year, on January 10th. Stay tuned to XBLAFans for more coverage of the zany action going down in Gotham in the days ahead.
