New details on Samus' next adventure arises. Read storyline details and more inside...

A new fact sheet for Metroid Prime 3: Corruption has been released. The game will be single-player only (no multiplayer or online), so those hoping for the online will be disappointed. The official storyline is as follows:

Six months have passed since the events on the planet Aether. 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, beginning with Samus, starts to contact bounty hunters. As they explain 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 is armed with immense power that no one can withstand. It soon becomes obvious that the forces controlling Dark Samus and the terror of the contaminated Phazon are a dire threat that could corrupt the entire universe.

The war is spread across many planets, and Samus must stop the Space Pirates corrupting each planet with Phazon Seeds, and then take down Dark Samus for the last time. Along the way, Samus will be corrupted by Phazon herself, and will have access to powerful abilities. Too much phazon, however, will cause her death. Samus' ship will also have an active role in the gameplay.

In case you missed them before, new screenshots can be found here. The game will be out in the US on the 20th August. European date is unknown.
