Microsoft is throwing a House Party on Xbox LIVE in February and they are generally bringing numerous new games to the Xbox 360 and Windows Phone 7 including the PC classic Torchlight for 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 rid of it on February 16. Hard Corps Rising could be the first game but no schedule was handed as to once the rest will likely be released. Presumably it is going to be one or two games each week over a month-long period you need to include some other almost incentive to acquire all of the games like previous promotions.
These will be the games in accordance with a Microsoft news release.
