Another interesting game on my radar is Gotham City Impostors. In short it is a downloadable game for PC, Xbox 360 and PS3 and it is only an online game. The game has a clever concept having 2 teams, one on Joker’s and the other on Batman’s side and they’re all impostors.
It goes without saying the gameplay and style is very similar to that of Team Fortress 2, fortunately this game actually looks good whereas TF 2 kinda flopped. Anyway, this game focuses a lot on customization and they’re pretty interesting and the game only supports 6 vs 6 but it might actually be fitting.
Since this comes out sometime in 2012, you may sign up for the beta starting from now.
