Microsoft is throwing a House Party on Xbox LIVE in February and they're bringing several new games to their Xbox 360 and Windows Phone 7 which range from 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 offers to kick it on February 16. Hard Corps Rising is definitely the first game but no schedule was handed as to if the rest will likely be released. Presumably it will likely be one or two games weekly over a month-long period and include some other kind of incentive to obtain all of the games like previous promotions.
These will be the games in line with website a Microsoft pr release.
