Easter Eggs
Bird Hunting on Tallon IV!: When you are in Chozo Ruins, look up. You will find many birds flying around, ready for the killing. Shoot at them, and you will see their feathers gently fall if you shoot them correctly.
Glitches
Early Space Jump Boots: As soon as you land on Tallon IV, get on top of the ship in the back-left area. Lock on dead ahead and dash (right while holding B) until you've gained enough speed and are right at the edge of the ship. Let go of the lock and dash, then press B while tilting the Control Stick all the way right. This propels Samus farther than usual and allows her to grab onto the edge of a cliff to the far right. Follow the path from there to get the Space Jump Boots! (NOTE: You can do this right when you begin on Tallon IV!)
Space Jump Boots Early: (PAL and NAPC) Unlike the NTSC version of this glitch, you cannot execute a dash jump via Scan Visor. Instead, head to the Temple Access (the room visible when you are finished saving on your ship). Lock on to the first Seedling and back up. Without letting your lock on reticule pass the door connecting the Landing Site with Temple Access, head back to your ship and carefully position yourself on the rear right thruster on the ship. Now, execute a dash jump (dash right, off of the ship, and let go of L when the dash is executed) and continue to the Alcove. Your Space Jump Boots await you!
Suicidal Wall Metroids: First, get a metroid latched onto you. Next, lay a bomb and position yourself next to a wall, so that when the metroid is dislodged, it gets stuck in the wall. Wait a couple seconds, and the metroid should simply explode. This is particularly useful against the Fission Metroids, especially when low on Power bombs.
Secrets
Easy Meta Ridley kill: During Ridley's second phase, use the Wavebuster. With enough Missiles, he dies in one hit.
Easy Metroid Prime (Core) battle: Near the point at which you start is something resembling a twig embedded into the ground. While standing on top of this twig, you are completely immune to Metroid Prime's shockwave, it's only (common) attack. The only things that can hurt you are the short range lunge attack and spawned Metroids, which fall easily anyway.
Curiously, while standing here, Metroid Prime will not change emission spectra without laying a pool of Phazon, which helps the fight along considerably.
Meta Ridley Quick Air Form: This trick makes Ridley much shorter. While in his air form, wait until he flies above you and crashes down on you. Before he flies back up, hit him with the boost ball. If done correctly, he will lose his wings and the ground form will begin.
Unlock Original NES Metroid/Metroid Fusion Suit: To unlock the original NES Metroid, simply beat Metroid Fusion on GBA, then link the GBA (with Fusion in it) to the GCN (with prime in it) then at the main menu of prime goto the bottom where it says GBA link bonuses or something like that. Make sure you have beaten Metroid Fusion though.
To unlock the Metroid Fusion Suit, do the exact same thing only dont beat fusion, but beat prime.
