Microsoft is throwing a House Party on Xbox LIVE in February and perhaps they are bringing numerous new games to both Xbox 360 and Windows Phone 7 between the PC classic Torchlight to a HD remake of Beyond Good and Evil together with Hard Corps Uprising.
The announcement of the House Party promotion came as soon as the Microsoft CES keynote with intends to kick rid of it on February 16. Hard Corps Rising would be the first game but no schedule was presented with as to website if your rest will likely be released. Presumably it are going to be one or two games weekly over a month-long period and include some other form of incentive to buy all of the games like previous promotions.
These are definitely the games based on a Microsoft news release.
