Microsoft is set to throw another House Party in 2012. In attendance will be Alan Wake's American Nightmare, EA's Warp, Nexuiz and the long-awaited I Am Alive.
The trailer for the XBLA House Party promotion, which was apparently posted by accident, does not reveal any release dates. Out best guesstimate, if history serves, would be late February like last time. We've contacted Microsoft for launch details.
Update: We snagged the trailer and have embedded it above!
