Microsoft is throwing a House Party on Xbox LIVE in February and they're bringing numerous new games to the two Xbox 360 and Windows Phone 7 starting from the PC classic Torchlight for an HD remake of Beyond Good and Evil along with Hard Corps Uprising.
The announcement of the House Party promotion came as soon as here the Microsoft CES keynote with promises to kick rid of it on February 16. Hard Corps Rising is definitely the first game but no schedule was presented as to if the rest will likely be released. Presumably it will probably be one or two games each week over a month-long period you need to include some other type of incentive to buy all of the games like previous promotions.
These include the games based on a Microsoft website article.
