Warner Bros. and DC Entertainment have recently announced Gotham City Imposters, a download-only first-person shooter where players battle for control of Gotham City overrun by impostors inspired by the DC Comics characters Batman and The Joker:

“Gotham City Impostors blows apart expectations for superhero games with an exaggerated take on first person shooters, set in a part of the DC Universe players have never seen before,” said Samantha Ryan, Senior Vice President, Production and Development, Warner Bros. Interactive Entertainment.  “Monolith is creating a game that turns Gotham City upside down and we think fans are going to have a blast with this creative twist on multiplayer heroism and anti-heroism as they play up the classic rivalry between Batman and The Joker.”
