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 which range from the PC classic Torchlight with an HD remake of Beyond Good and Evil along with Hard Corps Uprising.
The announcement of the House Party promotion came following your Microsoft CES keynote with offers to kick it well on February read more 16. Hard Corps Rising could be the first game but no schedule was presented as to once the rest will probably be released. Presumably it is going to be one or two games each week over a month-long period you need to include some other kind of incentive to obtain all of the games like previous promotions.
These will be the games based on a Microsoft news release.
