Gotham City Impostors’ life as a retail product was shortlived. Originally released in February 2012 to positive reviews, the Monolith Productions game is now available as free-to-play, or at least the PC version. No news yet about the PS3 and Xbox 360 versions.
Gotham City Impostors is a F2P FPS that offers fast paced combat with cartoon characters based on the Batman series. Players choose from the vigilantes dressed in Batman costumes or the Jokerz and enter exciting battles with strange devices. The game already has a few DLC available for purchase.
