Microsoft is throwing a House Party on Xbox LIVE in February and they are generally bringing numerous new games to both Xbox 360 and Windows Phone 7 between 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 following Microsoft CES keynote with offers to kick them back on February 16. Hard Corps Rising may be the first game but no schedule was handed as to if your rest will probably be released. Presumably it is going to be one or two games every week over a month-long period you need to include some other form of incentive to buy all of the games like previous promotions.
These include bola the games based on a Microsoft blog post.
