Microsoft is throwing a House Party on Xbox LIVE in February and perhaps they are bringing many 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 together with Hard Corps Uprising.
The announcement of the House Party promotion came as soon as the Microsoft CES keynote with offers to kick it well on February 16. Hard Corps Rising is definitely the first game but no schedule was presented with as to if the rest will likely online games free to play now shooting be released. Presumably it will probably be one or two games each week over a month-long period you need to include some other almost incentive to get all of the games like previous promotions.
These would be the games in accordance with a Microsoft blog post.
