Originally a launch title for Wii, Metroid Prime 3 is the 3rd (duh) and deemed last in the Metroid Prime trilogy.
"The trilogy ends ... with a bang! Six months have passed since the events on the planet Aether. The Galactic Federation's network computers, Aurora Units, are suddenly and completely corrupted with something like a virus, and only quick action saves the entire network from going down. The Federation believes Space Pirates may be behind the problem and, beginning with Samus, starts to contact bounty hunters. As it explains the situation to the assembled hunters, the Federation is attacked by the pirates. Samus and the other hunters leap to the defense of the Federation capital, only to find that the enemy the hunters face is the presumed-dead Dark Samus. Dark Samus defeats Samus and the other bounty hunters, corrupting them with Phazon in the process. They are all subsequently outfitted by the Galactic Federation with Phazon Enhancement Devices (PEDs) that can harness their corruption to enhance their powers. After learning to use this enhancement, called Hypermode, Samus sets off after Dark Samus, who has begun to seed other planets with Phazon by launching enormous Phazon seeds called Leviathans into them. As the Phazon begins to slowly corrupt Samus, the final saga in the Metroid Prime trilogy begins."
To celebrate the launch of the game in the US, we've created a fantabulous Metroid Prime 3: wallpaper and uploaded a copy of the US TV commercial for the game:
