Stop the unstoppable Dark Samus

If you think you knew what it felt like to be the bounty hunter behind
the visor, think again. The Galactic Federation's network computer,
Aurora Unit, is suddenly and completely corrupted with something like a
virus. The Federation believes Space Pirates may be behind the problem
and are soon attacked. Samus and other hunters leap to their defense
only to find that the enemy they face is Dark Samus, armed with immense
power that no one can withstand.

First-Person Perfect: Players control Samus by moving with the
Nunchuk and aiming with the Wii Remote controller, allowing for a
level of immersion unlike anything they have ever experienced. It's a
quantum leap in first-person control.

Wonderful Weapons: Samus employs well-known power-ups like the
Grapple Beam and Morph Ball, as well as new surprises, to help her
survive. Using the Wii Remote and Nunchuk controllers, players will be
able to grasp and pull things by using actual arm movements, as well
as execute amazing feats like aiming and blasting in midair or at a
full run.

Phazon's Powers: The game also incorporates a new system
involving Phazon. If you fill Samus' Phazon supply to a certain level,
Samus will temporarily go into hyper mode, a state in which she can
pull off incredible feats. On the flip side, if she exceeds the
maximum Phazon level, she'll perish. Also, for the first time in the
Metroid series, Samus' ship will be used in active game play.
