Metroid Prime 3: Corruption is a Wii video game and the final installment in the insanely popular Metroid Prime series which started near the beginning of the GameCube's life with the release of Metroid Prime. As the previous games in the series, it is commonly considered a first person adventure game by Nintendo rather than a first person shooter. Seeing that it was made for the Wii, the control scheme was re-invented, and uses the Wii remote to a great extent, most notably to aim your gun. The nunchuck also plays a rather large role - Its analog stick not only allows you to move Samus Aran around but you are now able to push your hand forward to solve certain puzzles and use your grappling beam more so than in previous games.
As mentioned before, the game takes full use of the Wii's capabilities. Rather than to stop and aim your gun as you had to do in previous games, you're now able to move while aiming thanks to the Wii's motion sensing remote. This allows the player to easily aim and shoot at their opponents.
While the actual ability to grapple is in no way new, it's been greatly updated in Corruption. Now, rather than just grappling onto a certain spot and swinging over to another ledge, you can now grab onto objects, pull shields away from your enemies, solve puzzles and more.
The game takes place six months after the events in Metroid Prime 2: Echoes. The game's protagonist Samus Aran is called in to inspect a malfunctioning computer. Conclusively the Galactic Federation assume that the Space Pirates are behind this, at which point their enemy army attacks them. Along with Samus, other friendly bounty hunters are also there, but after getting corrupted Samus has to fight them off one by one. Later on in the game Samus fights and permanently kills Metroid Prime[Dark Samus]. Meta Ridley is too featured in the game. Also, if a player beats the game and has collected all the special tokens, a short cutscene is presented before the credits, which shows Samus' ship being followed through space by a mysterious green ship.
Samus Aran - Samus is the main protagonist in Metroid Prime 3: Corruption and is a bounty hunter who wears a full-body Power Suit with many advanced technologies built into it, including an arm cannon, a grapple beam and the ability to morph into a ball.
Rundas - Rundas is a bounty hunter that was shown in the demo. Samus was cornered by four space pirate ships, and trapped, when Rundas came and froze all the ships and destroyed them. After that with the fight with Ridley, you get saved by Rundas right before you fall down a pit. It's expected that the bounty hunter will team up with Samus later in the game.
Gandrayda - A new mysterious character newly introduced to the Metroid series. She appears as a glowing purple female who's age is unknown, seeing that she is apparently un-scanable. Apparently she's a bounty hunter for sport, and seriously enjoys it.
Ghor - Ghor is a Wotan VII liberation war hero, and only 6% of his real body parts remain. He seems to be mostly a robot, and he also seems to be able to change parts, as he's been seen in an enormous suit.
Metroid video games usually don't have too many cameo appearances. However, this game features many more than the generally absence of cameos. Though to find the bumper stickers, you'll have to have the following game in your Wii console's memory...
