There's a battle to fight in outer space, but before you meet your fate, train yourself against the CPU to master all the tricks and combos. Whether playing one-on-one or against a group of three, your training will pay off once you challenge your friends and foes. Anyone can play, but only the well trained will win. Send your friends a demo via DS Download Play to allow them to play solo or in a Versus mode. Finding opponents for the Multiplayer mode is easy because only one player needs to have the game loaded onto his or her system. Let the fight begin!
