Microsoft is throwing a House Party on Xbox LIVE in February and they're bringing several new games to the Xbox 360 and Windows Phone 7 which range from the PC classic Torchlight in an HD remake of Beyond Good and Evil in addition to Hard Corps Uprising.
The announcement of the House Party promotion came following Microsoft CES keynote with intentions to kick it well on February 16. Hard Corps Rising may be the first game but no schedule was handed as to once the rest is going to be released. Presumably it are going to be one or two games every week over a month-long period you need to include some bola other kind of incentive to obtain all of the games like previous promotions.
These are definitely the games as outlined by a Microsoft blog post.
