Take a look right hereat the real fake Batmen and Jokers from Monolith's Gotham City Impostors in this in-game trailer, showing off close-quarters combat and innovative jack-in-the-box weaponry a la TF2 meets DCUO. We think Impostors looks like a heap of fun, but even if you don't, at least the characters themselves are having a good time -- half of the players can't seem to wipe those cheek-to-cheek grins off their faces.
