Gotham City Impostors, a multiplayer downloadable FPS from F.E.A.R. developer Monolith Productions, is in the works for PlayStation Network and Xbox Live Arcade.
According to Kotaku, you won't actually play as Batman but as a customisable "imposter" of one of the characters from either Batman's wider circle of friends or The Joker's motley crew.
Apparently you'll be able to tweak your load-outs, costumes and character stats for play across a series of different game modes and maps.
It'll be online-only, with available weapons including an assault rifle, shotgun, pipebombs, grappling hook and a firework launcher called the Thunder Dragon.
Monolith is yet to decide how many players the game will support but has stated there will be no bots.
No release date has been pinned down yet but we'll update as more information becomes available.
