Metroid Prime 3: Corruption cheats for the Nintendo Wii

There are two foreign language Easter Eggs in the game, both Dark Samus related. In the beginning, if you examine the life support system, the screen will fill with seemingly-random letters. It's actually French, though, and reads "Vous mourez si votre resistance est forte," which translates to "You die if your resistance is strong." Near the end of the game, you will also find some German text, which reads "Kampfen Gandrayada, die Zahl von einer falschen freund." This translates to "Fight Gandrayada, the figure of a false friend" (though the German is technically grammatically incorrect).

Hint - Stop The Boss
When Aurora Unit 313 is on the ground and spinning around, you can use the Screw Attack to stun it.
Hint: Complete Ending

By finishing the game with a 100% rating (meaning you picked up all one hundred pickups in the game), you will get a special ending.

Hint: Extended Ending

To get a special extended ending, beat the game with at least a completion at or above 75%.

Hint: Friend Credit Tips

Bowling for Bots: In Skytown, if you use Morph Ball to run over the Tinbots, you'll gain this bonus. Easiest place to do this is in the doughnut-shaped room.

Stylish Kill: In Skytown, there's a Bridge area that collapses when you cross it. Before it falls, there's a fight with Tinbots and the Master Bot. Ignore them and finish crossing the bridge. A cutscene with go off and show the bot fall to their doom.

Hint: Frozen Reptilian Voucher

To get a secret Friend Voucher, head to Bryyo and freeze the reptilian enemies that throw boomerangs at you. It requires great timing, but freeze them with your Ice Missiles when they throw a boomerang at you. The boomerang will come back at the reptilian foe and kill it. An on-screen message will confirm that you have indeed gotten the voucher.

Hint: Get Friend Vouchers Quickly

You can get a friend voucher for performing certain tasks that you can trade with other players who have the game. Once traded, these can be used for buying special extras. Among other things, you get a voucher for every 100 kills (up to 1,000). An easy way to rake in 10 vouchers is to look for swarms of small, explosive bugs that crawl around the levels after the Space Pirates attack. Just sit there and zap 'em and you can get to 1,000 kills fairly quickly.

Hint: GFS Olympus Voucher

At the beginning of the game when you are on the GFS Olympus, head to where your gunship is sitting. Adjacent to the ship will be two beacons that, when shot, will head upwards in the air. With careful firing, you can juggle the two beacons in the air, shooting them higher and higher. If you manage to hit one twenty times in a row without missing or the beacon hitting the ground, you will be rewarded with a friend voucher.

Hint: Harvest Voucher

In the Mining Zone of the Pirate Homeworld, use your gunship to destroy a Pirate Harvester. You'll receive a Friend Voucher in return.

Hint: Kenji Yamamoto's Message

Whenever Samus is in her ship, open her computer terminal (where there are eight button options, each a mysterious symbol). If you’re looking at the buttons from left to right, numbering them one through eight (for ease), insert this code: 3-6-4-8. If entered correctly, a secret message from Nintendo’s very own Kenji Yamamoto plays in Japanese.

Hint: Killing Helios

To kill Helios easily, fire at the open spots on his body until he reveals his Phazon center. When he does this, quickly go into Hyper Mode, and then into Morph Ball mode, and attack him quickly for an easy kill.

Hint: Lever Friend Voucher

When you're on Bryyo fighting the two anti-aircraft turrets, you can get a secret Friend Voucher. You will get it when destroying the second of the three turrets. You'll need to pull three levers to open the fuel cells to destroy the device. If you manage to pull all three levers without a Space Pirate resetting any levers, you'll receive a voucher for "Perfect Execution".

Hint: Nova Beam Voucher

In the room where you battle enemies in order to acquire the Nova Beam, keep fighting until you've killed at least twenty enemies before you physically acquire the Nova Beam. You'll get a friend voucher for your efforts.

Hint: Quick Morph Ball Kills

To quickly kill 1,000 enemies (and achieve the Friend Voucher easily), try using the Morph Ball. The bugs that grab onto you as you scale walls can be destroyed with the bombs from the Morph Ball. Doing this continuously for a little while will net you 1,000 kills rather easily.

Hint: Satoru Iwata's Message

Whenever Samus is in her ship, open her computer terminal (where there are eight button options, each a mysterious symbol). If you’re looking at the buttons from left to right, numbering them one through eight (for ease), insert the identical code Samus is given in the beginning of the game – 2-7-5-1. If entered correctly, a secret message from Nintendo’s very own Satoru Iwata plays in Japanese.

Hint: Shigeru Miyamoto's Message

Whenever Samus is in her ship, open her computer terminal (where there are eight button options, each a mysterious symbol). If you’re looking at the buttons from left to right, numbering them one through eight (for ease), insert this code: 8-3-5-4. If entered correctly, a secret message from Nintendo’s very own Shigeru Miyamoto plays in Japanese.

Hint: Unlimited Friend Vouchers

To execute this cheat, you'll need 2 SD memory cards. Copy and save your game from your Wii to one card, and then go back to your game on one card and send out your Vouchers. After you receive your Vouchers in return, save your game to the other SD card (so that you have an old save and a current save). Whenever you want to send more Vouchers, just save your game to the current SD card, reload the old save game, and send out more. Then reload the current save to receive the Vouchers. In this way, you can easily get as many Friend Vouchers as you want.

Hint: Yoshio Sakamoto's Message

Whenever Samus is in her ship, open her computer terminal (where there are eight button options, each a mysterious symbol). If you’re looking at the buttons from left to right, numbering them one through eight (for ease), insert this code: 4-6-1-7. If entered correctly, a secret message from Nintendo’s very own Yoshio Sakamoto plays in Japanese.
