Microsoft is throwing a House Party on Xbox LIVE in February and they're bringing several new games to the Xbox 360 and Windows Phone 7 including the PC classic Torchlight to a HD remake of Beyond Good and Evil and also Hard Corps Uprising.
The announcement of the House Party promotion came as soon as the Microsoft CES keynote with promises to kick it well on February 16. Hard Corps Rising would be the first game but no schedule was handed as to if your rest are going to be released. Presumably it are going to be one or two games every week over a month-long period you need to include some other kind of incentive to acquire all of the games like previous promotions.
These will be the here games based on a Microsoft blog post.
