Comic-Con has yet to officially start, but the nerd news we love is already rolling in. Gotham City Impostors -- a 12-player first-person shooter -- finally has some hard facts. The download is expected to launch in the winter of 2012 and should set you back $15 on the PlayStation Network or 1200 Microsoft Points on your Xbox 360. Gotham City Imposters is a competitive multiplayer FPS that breaks players into squads of people dressed in goofy Batman-like outfits or Joker-inspired outfits. IGN was a bit confused the last time we saw the game, but we're definitely ready to go another round with the demented Gotham City residents.[/p] Source Sounds good, same price as a Call of Duty map pack too- Activision, please take note. Please.
