Microsoft is throwing a House Party on Xbox LIVE in February and they're bringing numerous new games to the two Xbox 360 and Windows Phone 7 including the PC classic Torchlight in an HD remake of Beyond Good and Evil along with Hard Corps Uprising.
The announcement of the House Party promotion came following the Microsoft CES keynote with promises bola to kick them back on February 16. Hard Corps Rising may be the first game but no schedule was presented as to if your rest are going to be released. Presumably it is going to be one or two games every week over a month-long period and include some other form of incentive to obtain all of the games like previous promotions.
These would be the games in accordance with a Microsoft blog post.
