Batman doesn't kill or use guns, so how do you squeeze a team-based video game shooter out of that licence? Simple! If you're Gotham City Impostors, you plunder The Dark Knight Returns and Batman Beyond for imitation identity grist, imagining a city under siege scenario without either Batman or Joker. Players take control of numbskull geeks with faction threads and murder minds. Do you reckon there's any chance we'll get The Nixons too? I think the best we can hope for is a bat branded Team Fortress 2.
