GripShift fans will enjoy tons of bonus content including all-new single-player and multiplayer modes, eight new Race Tracks, eight new Deathmatch Arenas, and eighteen brand new music tracks.

"With Turbo, we wanted to extend the GripShift experience for fans that loved the game's initial content," said Mario Wynands, Managing Director of Sidhe Interactive. "GripShift Turbo's bonus single-player mini-games will ensure endless excitement for veteran players, while the new multiplayer mode gives new players a competitive edge. Penguin Bowling, the popular mini-game from the PSP version, is returning with as much penguin crushing excitement as ever."

The Turbo Expansion Pack has brand-new single-player bonus mini-games, including the immensely popular Penguin Bowling and challenging Playground, as well as the exciting Snaker. Reverse Tag, the new multiplayer mode, challenges competitors to master their wit, weapons, and skills like never before.

The Turbo Expansion Pack for GripShift on Xbox LIVE Arcade is available for download now from the Xbox LIVE Marketplace for only 350 Microsoft points.
