X-Orbtek II is a new blend of arcade style gameplay. You'll be chasing after orbs whilst dodging swarms of enemies. If all the orbs disappear it is game over so the game is quick paced arcade highscore chasing gameplay.
Be warned - the enemies will take shots at you but you're not defenseless. Blast them back or use your mines, bombs or pickups to clear out enemies. Alternatively choose one of the non-combat modes (or custom mode) to remove combat and just chase after orbs.
There's also local multiplayer and with four players it can be insanely good fun! If you get the opportunity to play with a couple of friends, I'd recommend it.
You can pick it up now for just 80 Microsoft Points!
