Game-makers at Capcom are working on a Top Secret, hush-hush game for the 360. The game is reportedly in the testing phase, so lucky Bay Area QA guys are playing it as we speak.
Is it a new IP? A sequel to an existing Capcom franchise? Los Planet Colonies? We'd tell you , but then we'd have to kill you. Sorry.
Until the announcement, feel free to speculate!
