Dual screens? Double the action, double the characters, double the trouble... Mega Man ZX. Mega Man brings the action to the Nintendo DS like never before, with ZX. For committed fans and new-to-the-series action-addicts clamouring for ZX, it's Mega Man, only bigger, badder, better than ever before. You better believe it, partner! Hundreds of years have passed since peace has been declared between humanity and its robotic Reploid enemy. But it's a fragile peace. Reploid Mavericks scavenging for weapons frequently clash with the human Serpent Company protectors of the "Outer" region. In this lawless area, two couriers find themselves under attack by a mysterious group of Mavericks, intent on grabbing the parcel the Girouette Express' finest are protecting. In the attack, the strange biometal the pair of couriers are transporting is absorbed by them - now Vent and Aile are transformed! Humans with biometal? Now they're as tough as the mighty Mega Man. They're tougher than any bunch of Reploid Mavericks, that's for sure. Augmented with new powers, Vent and Aile can meld together different biometal fragments to gain new abilities and take the action to the next level! The only problem? Those Reploid Mavericks have had the same idea, friend. Choose the male Vent, or for the first time ever in the Mega Man series, the heroic female Aile, each with their own unique abilities, to do battle against the toughest Maverick bosses. Take down the Maverick bosses, grab their biometal artefacts, and gain new abilities. It's time to take the fight to the "outer" regions, and bring the biometal back home in Mega Man ZX, the best there's ever been...
