Warner Bros has just released a new trailer discussing the Beta announcement. Gotham City Impostors is a download only title that will be available on XBox Live and the Playstation Network. Gotham City Impostors is an original download-only first-person shooter where up to 12 players battle for control of an unhinged Gotham City overrun by Impostors inspired by the DC Comics characters Batman and The Joker. Gotham City Impostors is an online multiplayer game unlike any other, giving players the opportunity to engage in unconventional urban warfare as they personalise their own Impostors. Gamers will create their very own version of the Bats or the Jokerz characters using unprecedented customisation options including insane costumes, homemade gadgets and a wide range of traditional and inventive weapons. The game will feature maps and modes inspired by DC Comics’ Batman license. Check out the new trailer and click here to register for your chance to take part in the beta.
