Is the previous-gen Xbox dead? Not if you ask Eidos. The top-tier publisher is set for a June 13th release of Urban Chaos: Riot Response: a first person shooter specifically for the big black box.
Why release a fully featured, last-gen Xbox game? That's an easy one: the sheer number of consoles already in the market. Eidos can get a return on their investment immediately with a good FPS for the Xbox, as UK's Rocksteady gets valuable experience for a future next-gen release.
