Overview
Metroid Prime 3: Corruption is the tenth game in the Metroid series, and the final game in the Metroid Prime trilogy. Like the other games in the Metroid Prime series, Corruption was developed by Retro Studios. Corruption sees the series make its first transition from the GameCube onto the Wii.along with the first implementation of motion controls which would later be brought to updated versions of Metroid Prime and Metroid Prime 2 for the New Play Control series and Metroid Prime Trilogy release.

The main difference between Corruption and the previous Prime games is its control scheme. Corruption makes substantial use of the motion sensing Remote. While the player still has the option to lock-on to any opponent on the screen and strafe around that foe, the control scheme allows Samus to freely fire at any on-screen enemy by simply pointing the remote at the screen, while using Wii Remote gestures for contraptions such as levers and the grapple hook. The standard gameplay elements of the Metroid series are still largely present in Corruption. The player once again takes the role of bounty hunter Samus Aran, who visits multiple planets this time around. As expected, Samus explores different areas while earning new abilities that allow her to overcome previously impassable environmental obstacles.
Gameplay
Corruption is a traditional first-person shooter, similar to the previous two Metroid Prime games. Corruption is controlled using the Wii Remote's motion sensor. The player can aim and shoot using the Wii Remote and Nunchuk combination (the Nunchuk's analog stick controls movement while the Wii Remote controls viewpoint). The Wii Remote also controls other actions, such as jumping and firing.
Corruption takes place across a variety of planets in the world of Metroid Prime. Several of these planets have been overtaken by Phazon, an incredibly dangerous substance that Samus has been exposed to (thus granting her special Phazon based abilities). She can go into a hyper mode, in which her Phazon meter keeps her in that mode. She is much more powerful in this mode, and can destroy Phazon corrupted objects and enemies.
The game also contains a variety of puzzles relating to Samus' abilities. For example, she uses her Morph Ball ability to go into smaller areas and use the bomb to trigger certain events. Samus' visor has many of her other abilities, in addition to having the heads-up display. Other visors can be unlocked, from an X-ray visor to a heat vision visor.
Plot

Corruption stars Samus Aran, the main protagonist of the Metroid franchise. Samus Aran and three other bounty hunters (Gandrayda, Ghor, and Rundas) are called to the Galactic Federation for a meeting with the leader of the organization, Admiral Dane. He briefs the bounty hunters on a crisis that has been occurring in the galaxy. Admiral Dane says that many of the Aurora Units (biological supercomputers that are linked in a network across the galaxy) have contracted a computer virus, causing them to malfunction. The meeting ends when the fleet is attacked by Space Pirates.
On Norion, there is a Galactic Federation naval base. This base is being barraged by attacks from Space Pirates. The bounty hunters are all sent to Norion to help defeat the attacking Space Pirates. While fending off the Space Pirates, Samus learns of a large, Phazon-covered asteroid called a Leviathan Seed that is about to crash into the planet. After getting all of the defense systems online and preparing for departure, the group is attacked by Dark Samus, who leaves all of the bounty hunters unconscious (save for Samus, who triggers the defense system just in time).

Samus stays unconscious for a month. When she wakes up on a Galactic Federation ship, it is revealed that she has been corrupted with Phazon, the incredibly mutagenic substance that Dark Samus specializes in. To combat this Phazon, Samus is given a Phazon Enhancement Device (PED) that allows her to use the Phazon produced by her body as a power source. The other bounty hunters had awakened much earlier, and were already sent off to investigate other planets. Samus is initially sent to two planets, Bryyo and Elysia, to search for these missing bounty hunters. Here, she finds that to combat the Phazon corrupting the galaxy, she must destroy all of the Leviathan Seeds embedded in various planets.
The Space Pirates are intent on stopping Samus from attaining this goal, however, sending forth various creatures that have been exposed to this mutagen. Samus also encounters her fellow bounty hunters, who, unable to control their PEDs, were completely corrupted. As the game progresses, Samus gradually becomes further corrupted with Phazon. After investigating the Space Pirate Homeworld, Samus finds that all of the Phazon has been coming from Phaaze, a planet accessible only via a wormhole created by a modified Leviathan. There, she confronts Dark Samus and a corrupted Aurora Unit 313. She defeats them in combat, and as a result Phazon is eradicated from the galaxy. The game ends with Samus flying off into space, with a ship resembling Sylux's (a bounty hunter from Metroid Prime: Hunters) ship following her.
