This 12 month subscription will cost $69.99 and you'll get a communications headset, the Xbox Live arcade game "Billiards", a $20 discount on an Xbox 360 game purchase and 200 points to spend in the Xbox Live marketplace where you will be able to download new levels, characters, items, ... for games.
