Hyper Mode Difficulty
Beat the game and you will get Hyper Mode Difficulty
Extended Ending
Collect at least 75% or more of suit upgrades to view an extended ending once you complete the game.
100% Ending
Collect all 100 pickups to view a secret ending clip after the game credits.
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. There will be four panels. Shoot one until it explodes. Repeat this until you have shot all four.
Defeating Pirate Commandos
Select your X-ray visor, then lock onto a Space 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 hits it.
Defeating Pirate Berserkers
Use the following trick when you encounter a Pirate Berserker (which happens often). This huge 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 about three times, a red light should pop up on his head. Go into hyper mode and blast
way at it. This should not take too long. Then, collect the health and continue on your journey.
Defeating Omega Ridley
Whatever you do, do not 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 blast 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 your Hyper mode and kill him.
Japanese messages
When in your ship at the beginning of the game you will eventually be asked to input your security clearance on a console.
Afterwards, activate the console again and input the same sequence: the character second from the right, the "X" like one
that is second from the left, then the three dots above a line fourth from the right, then the pyramid made of three line
on the far left. 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."
Secret Message from Miyamoto
When in Samus' ship, go to the radio and press the following symbols:
Going from left to right, press the eighth symbol, the third symbol, the fifth symbol and then the fourth symbol.
You will then hear a message from Mr. Miyamoto!
Secret Message from Yoshio Sakamoto
When in Samus' ship, go to the radio and press the following symbols:
Going from left to right, press the fourth symbol, the sixth symbol, the first symbol and then the seventh symbol.
Reveal all item locations
Go to the place in Skytown when you get the first part of the bomb you have to make using your ship. Near the bottom there is
some Phazite, shoot the switch inside to activate the satelite system. Go to the top and go around the walls using the spiderball
tracks and bomb all the slots to get markers on your map for where every expansion(missle,ship missle,and E tanks) is in every
part of the game, except the items that are in the Valhalla
Get Friend Vouchers Quickly
You get friend vouchers for performing certain tasks. You can then trade with other players who have the game. These can be used
for buying special extras. You get a voucher for every 100 kills. An easy way to rake in 10 vouchers is to look for swarms of
explosive bugs that crawl around the levels after the Space Pirates attack.
Hyper Missiles
The Hyper Missiles are earned in Hyper Mode after getting to Seed in Skytown. Hyper Missiles are the most powerful weapon in the game.
Crash Landing Friend Voucher
Find a Pirate Aerotrooper and use regular beam attacks to stun him. Then use your grapple lasso to remove his armor and weaponry.
Doing so will get you this Friend Voucher.
Reptilian Voucher
Head to Bryyo and find the reptilian enemies. Wait for them to throw a boomerang than freeze them. The boomerang will come back
at the reptilian foe and kill it. An on-screen message will confirm that you have gotten the voucher.
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 grab the Nova Beam.
GFS Olympus Voucher
At the beginning of the game when you are on the GFS Olympus, head to where your gunship is sitting. Next to the ship will be two
beacons that when shot will head upwards in the air. With timing 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 a miss or the beacon hitting the ground, you will get a friend voucher.
Lever Friend Voucher
When 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 pull all three levers
without a Space Pirate resetting any, you'll receive a "Perfect Execution" voucher.
A rough translation:
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.
Secret Message from Kenji Yamoto
When in Samus' ship, go to the radio and press the following symbols:
Going from left to right, press the third symbol, the sixth symbol, the fourth symbol and then the eighth symbol.
You will then hear a message from Mr. Yamoto!

Zebes reference

that can be found on the Pirate Homeworld. Land your ship at the Research Facility and find the place on the map called

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.

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

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.
