We knew that Warp, Alan Wake's American Nightmare, Nexuiz, and I Am Alive would be participating in Microsoft's 2012 Xbox Live Arcade House Party promo, and we knew that the party would start on February 15, but we didn't have a clue as to how the specifics of the boogeying would progress. Today, Microsoft revealed that Warp will be the party's first attendee, arriving on February 15 for the nice price of 800 MS Points ($10), followed up in the proceeding three weeks by Alan Wake's American sojourn, the almost-but-not-quite-Quake multiplayer shooter Nexuiz, and one man's journey through the depths of human survival in I Am Alive.

Like Warp, Nexuiz will only cost 800 MS Points ($10), while the other two titles will run 1200 MS Points a pop ($15). As always with these XBLA promos, Microsoft is offering an extra 800 free MS Points to anyone who grabs all four games within a defined time period (between Feb. 15 and Mar. 13 in this case). As for what to do with those extra points ... well, might we suggest hanging onto it for the upcoming launch of Fez? 'Cause that's totally what we're doing.
