Microsoft is throwing a House Party on Xbox LIVE in February and they're bringing many 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 your Microsoft CES keynote with offers to kick rid of it on February 16. Hard Corps Rising is definitely the first game but no schedule was presented with as to in the event the rest is going to be released. Presumably it are going to be one or two games weekly over a month-long period and include some other kind of incentive to acquire all of the games like previous promotions.
These website would be the games based on a Microsoft website article.
