The next Xbox 360 "House Party"—a promotional rush of a bunch of new downloadable games, probably released one a week—will be headlined by Alan Wake's American Nightmare, according to a trailer that's leaked through Xbox.com. Joystiq noticed it and we've watched it: It also includes the cool top-down body-hopping/barrel-possessing Warp, the disaster-survival game I Am Alive and the multiplayer shooter Nexuiz.

The trailer gives no date for the House Party, but with most, perhaps all, of these games being shown at the Consumer Electronics Show this week, they're far along and likely close to release.
