Microsoft is throwing a House Party on Xbox LIVE in February and perhaps they are bringing several new games to the Xbox 360 and Windows Phone 7 including the PC classic Torchlight in an HD remake of Beyond Good and Evil and also Hard Corps Uprising.
The announcement of the House Party promotion came following your Microsoft CES keynote with intentions to kick rid of it on February 16. Hard Corps Rising would be the first game but no schedule was presented as to if the rest is going to be released. Presumably it will likely be one or two games weekly over a month-long period you need to include some other get more info form of incentive to get all of the games like previous promotions.
These would be the games in accordance with a Microsoft blog post.
