Players will race as one of six unique characters in supped-up, customizable vehicles as they stunt their way through insane twisting levels while collecting power-ups, avoiding traps, beating the clock and challenging friends. With unlockable racing circuits, bonus games and the ability to create custom tracks with the in-game Track Editor and share them with other players, GripShift offers an original and compelling gameplay experience.

A re-mixed version of GripShift speeds onto Xbox Live Arcade with a complete set of upgrades and new features. In this definitive version of the game, players will enjoy improved controls, enhanced HD graphics, additional single player courses and intense, friend-fragging Deathmatch arena battles. A full set of achievements and TrueSkill Leaderboards give Xbox 360 players even more of a reason to jump, blast and speed their way past the competition to become the true GripShift guru.

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.
