Microsoft is throwing a House Party on Xbox LIVE in February and they are generally bringing several new games to their Xbox 360 and Windows Phone 7 including the PC classic Torchlight with an HD remake of Beyond Good and Evil in addition to Hard Corps Uprising.
The announcement of the House Party promotion came as soon as the Microsoft CES keynote with intentions to kick them back on February 16. Hard Corps Rising could be the first game but no schedule was presented with as to if your rest are going website to be released. Presumably it is going to be one or two games per week over a month-long period and include some other kind of incentive to get all of the games like previous promotions.
These include the games as outlined by a Microsoft pr release.
