The war initiated by Dark Samus and the Space Pirates rages across many planets as they attempt to corrupt each with Phazon seeds. Players use the Wii Remote and Nunchuk to explore alien landscapes, hunt for weapons and information, and destroy the seeds. Saving the planets from Corruption isn't enough, though. Eventually, players must take down Samus' mortal enemy, Dark Samus.

Besides using the Wii Remote and Nunchuk controllers to pull off amazing feats like aiming and blasting in midair or at a full run, players also will have an array of different weapons at their disposal. In true Metroid fashion, these will become powered up as the game progresses. Not only that, but the controller will be used for a number of other game elements beyond the traditional firstperson shooter standards.

• You ARE Samus with Wii control!: By moving around with the Nunchuk and aiming Samus's gun with the Wii Remote, you'll do more than look through the eyes of Samus- you'll experience a quantum leap in first-person control. Fire on the run, grapple enemies and yank off their shields, or manipulate machinery with movements of the Nunchuk and Wii Remote - it all adds up to a level of immersion only possible on the Nintendo Wii, and the best first-person controls on any platform, period.
• Corruption is everywhere.....Dark Samus, Samus's longtime nemesis, is corrupting entire planets by luanching enormous seeds called Leviathans into them. Samus must travel to multiple planets - each with unique alien landscapes and dangers - to fight the corruption and track several other bounty hunters, all the while fighting and spreading Phazon that threatens to take over her body completley. As it corrupts her, it also grants her incredible powers.
• Enter Hypermode!: Samus will employ a never-before-used device called the Phazon Enhancement Device (P.E.D) that harnesses the Phazon within her and puts her into a state called Hypermode. In Hypermode, Samus can destroy Phazon impediments and annhilate enemies with superpowered weapons... but it drains her health to use it, and she risks utter corruption if she doesn't empty her Phazon meter within a certian time frame. You'll need to carefully balance your need for ultimate power with the inherent danger of corruption.
