If you need a break from the multiplayer mayhem, Ubisoft has now also released the Splinter Cell Double Agent singleplayer demo, while Take Two has issued a demo (only for North America) for its recently released basketball game College Hoops 2K7 (North Carolina V.S. Florida). Both demos are now available on Xbox Live, but for the time being only Gold members will have access to download them, silver membership holders will have to wait until next week, to shoot some hoops.
