Microsoft is throwing a House Party on Xbox LIVE in February and perhaps they are bringing several new games to their Xbox 360 and Windows Phone 7 including the PC classic Torchlight to a 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 check here game but no schedule was presented as to if your rest are going to be released. Presumably it will likely be one or two games each week over a month-long period and include some other form of incentive to obtain all of the games like previous promotions.
These include the games as outlined by a Microsoft website article.
