Once you get the Spider Ball, go back to the Chozo astronomy lab in Skytown, Elysia where you must get the first part of the bomb you have to make using your ship. Near the bottom is some Phazite; shoot the switch inside to activate the satellite system. Go to the top, and go around the walls using the Spider Ball tracks, and bomb all the bomb slots to get markers on your map revealing the location of every expansion (Missile, Ship Missile, and E-Tank) in every part of the game, except the items in the Valhalla.Easy Friend Vouchers
Go to any Morph Ball area that has the little roach-like critters on the walls. Simply roll back and forth dropping bombs to easily get hundreds of kills and lots of Friend Vouchers.
Once you get the Ice Missiles and encounter a Reptilicus (the four-armed lizard creatures on Bryyo), wait until he throws his boomerang at you. Immediately fire an Ice Missile at him. While frozen, the boomerang will come back and shatter the Reptilicus, earning you a Friend Voucher.
In SkyTown, encounter a group of Steambot enemies. As a Morphball, use the Charge ability to glow and shoot through at least two or more Steambots, cutting out their legs. Keep doing this to get Friend Vouchers.Easy Green tokens
Note: This trick requires two Wii systems. Earn Friend Vouchers, then copy your saved game file onto a SD card. Put the SD card in the second Wii system. Copy the saved game file onto that Wii's internal memory. Load the game, then send the Friend Vouchers to the first Wii. Then, load your game on the first Wii to get the Friend Vouchers and convert them into Green tokens. Recopy your new saved game file onto the SD card, and repeat the process as many times as desired.Double bomb jump
Lay one bomb, then exactly at the moment it explodes, lay a second. At the peak of the jump, lay the last bomb. The second one will explode, and just when you get to the top one, it will explode.Hidden messages
While in your ship at the beginning of the game, you will eventually be asked to input your security clearance on a radio console. Afterwards, activate the radio console again, and input the same sequence of symbols in order (numbered from left to right): 2, 7, 5, 1. You will hear a message in Japanese from Satoru Iwata, the president of Nintendo. The translation is "Hello, this is Iwata from Nintendo. A president has to take things really seriously, even if it doesn't seem like it. It's understandable if you lose weight from stress... but I get fatter instead. Nobody thinks I'm taking it seriously."
Go to the radio in Samus' ship, and input the following symbols in order (numbered from left to right): 8, 3, 5, 4. You will hear a message in Japanese from Shigeru Miyamoto, the creator of the Mario, Donkey Kong, The Legend Of Zelda, Star Fox, Nintendogs, Wave Race, and Pikmin game series. The translation is "Ah, can you hear me? This is Miyamoto. All of you playing Metroid, can you hear me? It's fun, isn't it? I've also worked on many [Metroid] games, but this one is the best yet, don't you think? Definitely play it all the way to the end. See you!"
Go to the radio in Samus' ship, and input the following symbols in order (numbered from left to right): 3, 6, 4, 8. You will hear a message in Japanese from Kenji Yamoto.
Go to the radio in Samus' ship, and input the following symbols in order (numbered from left to right): 4, 6, 1, 7. You will hear a message in Japanese from Yoshio Sakamoto, co-creator of the Metroid series.
Go to the radio in Samus' ship, and input the following symbols in order (numbered from left to right): 1, 3, 8, 5. You will hear a message in Japanese from Kensuke Tanabe.See Samus "Corrupted"
After you destroy the first Seed, look at the reflection of Samus' eyes in her visor when the scanning visor is equipped. You can see black streaks of Phazon on her face that get progressively larger after each Seed is destroyed.
Dodge all of its attacks while trying to destroy the tentacles. Shoot into the hole the tentacles go into when they are yellow. After it falls to the ground, grapple its head, and pull off the cover. Charge up your Hyperbeam, and blow it up. Repeat this until it is dead. When Dark Samus' come out, destroy them quickly. They are easier to defeat then the other Dark Samus clones.Defeating Dark Samus
Charge up your Hyper Beam, and hit her with it while dodging her attacks. If she floats into the air, destroy her. She will try to heal. When the clones start appearing, destroy them with your charged Hyper Beam, and get back to the real Samus. She should be dead soon.Defeating Elysia (Seed Boss)
When he is exposed, keep shooting him with single shots from your plasma gun. At certain times during the fight, you will not be able to hurt him. Scan him with your visor, and it will tell you how to get him exposed to your shots. He will have many different forms in which you have to make him exposed. After many shots to his body, he will open up. Go into Hyper mode, and shoot him, making sure he does not run into you. Keep doing this until he has been defeated.Defeating the Leviathan Infant
In the room before Dark Samus on planet Phaaze, there is a small Leviathan seed in the middle. Pull off the two sides of it using your Grapple Beam first. Then while dodging and blowing up Metroids, shoot the Leviathan Infant inside with single shots from your Hyper Beam. It will continually switch sides; follow it. After doing this for a few mintues, it should die.Defeating Metroid Hatchers
Start by shooting its tentacles until they are all retracted. Then, shoot him in the mouth repeatedly until grapple symbols appear. Use them to rip off its tentacles. After all four are gone, it will be dead.
Use the following trick to kill Metroid Hatchers and Metroids with one hit. It requires the Nova Beam and X-ray Visor. Turn on your X-ray, and lock on to either a Metroid Hatcher or Metroid. When you lock on, you will see a red spot and an "up close" of the enemy will appear. If you can shoot this spot, the creature will die instantly. Note: These are not the only creatures this affects. Pirate Commandos are also affected, and this technique must be used on Omega Ridley.Defeating Mogner War Golem (Boss of Bryyo)
To defeat Mogner War Golem (Boss of Bryyo), first dodge and jump over all of his attacks. While doing this, use missiles and your Power Beam to blow up the red orbs on his chest. Try this order: first the stomach, then the shoulders, and finally the back. Shoot them until they are giving off white light. Then, use your Hyperbeam to blow up the now white orb. Do this for all four of them. After you destroy one, the Golem will try to run into you and use his "little jump and create waves of pain" attack. Every time he is about to jump, use Morph Ball Bombs on his feet. They should explode, and you can continue fighting him. Also, when he starts to make red orbs come to his hands, blow them up or you will have to destroy his orbs again.Defeating Omega Ridley
Once the battle begins, try not to get hit. Besides that, just shoot him in the mouth whenever you get the chance. When he is stunned, rip open his chest with your Grapple Beam, go into Hyper mode, and shoot away. Repeat this until he gets armor over his chest. When he is stunned, go into your X-ray Visor, and shoot his shoulders. You will then be able to shoot his chest. Use Hyper mode, and kill him.Defeating Pirate Berserkers
Use the following trick when you encounter a Pirate Berserker (which happens often). This large creature has two red lights on its shoulders. While dodging its shots and "waves of pain", destroy these lights using your beam and missiles. When they are both destroyed, wait for it to shoot purple orbs. Dodge the red ones, as they will hurt you. Shoot the purple orbs, and they will fly back at him. After doing this approximately three times, a red light should pop up on his head. Go into Hyper mode, and start shooting at it.Defeating Pirate Commandos
Select your X-ray Visor, then lock onto a Pirate Commando. A small screen will appear showing an "up close" of the Commando. You should now be able to see a small red spot where its face should be. If you can manage to shoot this spot, he will die instantly. Two to five rapid fire shots usually kill them.Defeating the Boss guarding the Nova Beam
Kill all the Space Pirates except for one. When the sucking beam enters the room, kill the Space Pirate and it will get sucked into the beam. Then, look up to see four panels. Shoot one until it explodes. Repeat this until you have shot all four.Rhundas gets stuck
When fighting Rhundas, you can sometimes get him stuck in wall by firing a missile when he is directly in front of it. Once you do this, he will stay in his neutral position and can be easily killed.Metroid Prime reference
Look closely on planet Phaaze just before you fight Dark Samus to find a body of Metroid Prime. You can even scan it.Tallon IV reference
At the Chozo observatory in Skytown, Elysia, when you put a Morph Ball bomb in certain bomb slots, it will say you now have more information about Tallon IV, from Metroid Prime.Zebes reference
There is a reference to Planet Zebes (the planet that Samus visited during the original Metroid and Super Metroid) that can be found on the Pirate Homeworld. Land your ship at the Research Facility, and find the place on the map called Metroid Processing. When in this room, you will find an empty tank next to the Spider Ball rail. Scan the tank to get the following message: "Data decoded. Zebes specimen. Highly aggressive subject has been transferred to an off-site laboratory."Incorrect dialogue
When you scan the Aurora Unit 313, it will say "Blow up the inner core to damage the tentacles". Actually, you must attack the tentacles to be able to attack the core area.
