Microsoft has filled in some of the blanks on the Xbox Live Arcade House Party Promotion. We knew that it was going to kick off on the 15th of February and that it would feature a number of titles, but now we know the titles and the pricing.

Warp – 800 Microsoft Points ($10) – February 15th

Alan Wake’s American Nightmare – 1,200 Microsoft Points ($15) February 22nd

Nexuiz – 800 Microsoft Points ($10) – February 29th
