Sega twists some metal on Xbox 360 with this fast-paced car-combat game. (That's okay, however, since the game also offers a chance to "untwist" errors at will.) Players pilot believable modern automobiles, equipped with destructive weaponry, through a variety of courses that challenge both kart- and arcade-style racing skills. The ultimate goal is to be first across the finish line, but that doesn't dissuade the heavy artillery action along the way. Many vehicles feature a gun-type weapon in front and a bomb-dropper in back, but new cars and configurations are unlocked with progress through the single-player "Career" mode. Especially notable among this game's features is the ability to rewind and "unwreck" mid-race, allowing the player to correct fatal mistakes even after they're made. Two-player split-screen competition is supported, as well as full-on multiplayer auto combat for as many as eight over the Xbox Live service.
