18 cert, EA/Trapdoor, Xbox Live (also PC, PlayStation 3) ****

Warpopens with the capture of a little yellow alien. The prisoner ambles around the lab like a caged animal, quietly planning revenge. Some of the villains are typical sci-fi characters, such as vain, cowardly scientists, while others could be the heroes of other games, such as trigger-happy security forces. The adorable alien is trying to escape a high-tech, high-security building. He has (among other tricks) the power to teleport (or "warp") past motion detectors, through walls, and even into humans. You can cause people to pass out, or wriggle about inside until they explode! Warpis a satisfying stealth/action/ puzzle game, original and challenging. Don't let its cute appearance fool you because (a) it can be demanding, both in the puzzles and the dexterity required, and (b), this is a surprisingly bloody game.
