Metroid Prime 3: Corruption Walkthrough

Make your way to the Chozo Observatory, then go to the bottom of the  room.  Somewhere around the base of the pedestal there is a small patch  of Phazite.  Turn on your x-ray visor, then shoot the glowing thing  behind it.  The pedestal will open up, revealing a switch.  Press it.   You now have the expansions for the Pirate Homeworld marked on your  map. Fly back to the Pirate Homeworld, Command Centre.

Pirate Homeworld, and Omega Ridley
Make your way to the room called “Flux control” on your map.  It can be  reached through “Command Courtyard”, by using the morph ball tunnel on  the right side of the room.  Once you take the tunnel, work your way to  the bottom of the room, until you come to a panel in the floor that can  be manipulated by the grapple beam.

Yank it, then go through the hole  you uncovered.  Then follow the spider ball tracks to get a Missile Expansion.  Then continue upwards on them, and when you drop down,  power up the switch in front of you with your grapple voltage.  Don’t  take the elevator down, but head to the room called “Defence Access”.

Once you get there, turn on your x-ray visor and shoot at the red dots  in the Phazite panel ahead of you.  Then go through the green door you  uncovered, and after dealing with the enemies, circle the room until  you come to a grapple voltage switch.

Drain it, then work your way to  the top of the room by jumping on platforms.  Turn on your x-ray visor  and activate the switch.  Keep the visor on to take out the pirates  easily, as well as shoot the glowing balls in the central column.  As  you do, a bomb slot at the top of the room will be more and more  uncovered.  When it is all the way open, go up, and bomb it.  Your pals  from the federation will come in and shoot the place up a bit, then  they will tell you to go to the room past command courtyard, so do so.   You might want to go back to your ship and save first.  Whatever you  decide, when you get there, a huge GF ship will drop a pod full of GF  marines and Admiral Dane himself.

The demolition troopers will tell  you to protect them, so basically kill all enemies around here as  quickly as possible.  You will go through a series of rooms, but none  of them have very complicated puzzles, so just clear each one and move  on.  If all 12 demolition troopers die, you lose, so don’t let that  happen.  The first door ahead requires use of the Grapple Voltage, so  do that, then shoot all of the pirates in this room, then go to the  next one.  Here, it is the same procedure as the last room, so clear it  and move on.

Keep on clearing roomfuls of pirates until you get to a  Berserker Lord.  Now that you have the x-ray visor and nova beam, these  guys die easily.  Just turn on the x-ray visor, lock on, and shoot the  glowing red part a couple of times.  He’s dead.  Take out the pirates  at the other end of this room, then one all in red will show up with  some elites (the ones you can kill with the x-ray visor and nova beam).

Take out the elites, then go to the switch to the right of the big door  that the demolition troopers just blasted.  Drop down, go the right,  and forward.  There will be a switch, so press it, then go through the  big door you just opened.  In the next room, go up to the green ledge  by way of the platforms, and you will be ambushed.  It will be against  the pirate all in red.

Pirate Commander Boss
This boss fight is like fighting a normal enemy, except he takes  forever to die.  He will call in elite pirates, so deal with those the  way you always do, and just shoot at him in hypermode and dodge his  attacks until he dies.

Make your way to the green ledge, then climb up and activate the  switch.  Then go left or right, drop down, and call in an air raid.   Your ship will wreck the doors, then automatically land.  Save, then  fly to the Seed.  When you land at the seed, go through the usual door,  then the usual barriers, this time enhanced by a need to use the x-ray  visor and nova beam in concert.  Do that, then go through the door and  drop down to face Omega Ridley.

Omega Ridley Boss Fight
First thing to do to deal with him is shoot his mouth when it glows  orange, then yank the plate off of his chest, then go into hypermode  and shoot the Phazon core.  Once you get him down to about 2/3 health,  he will get a stronger chest plate.  To deal with this, activate the x- ray visor and shoot at the glowing red parts, which are structural  weaknesses in his armour.

He’ll have to be stunned to do this, which  involves either shooting him in the mouth again, or shooting both blue  orbs when he tries to make them to throw at you.  He has an annoying  attack where he breathes a jet of flame and charges up his tail and  spins around, simply jump over those.  He also charges a lot, but he  stands still and folds his wings up, so it is easy to tell when.

Once  his armour is off, he will start flying around, and dropping bombs on  you.  Use your radar to find where he is going to emerge, and when he  lands, shoot at him in hypermode after stunning him by shooting him in  the mouth.  Do this enough and he will die.

go to the upgrade canister to get the Hyper Grapple!  This is like the  grapple voltage, but it overloads things with Phazon instead of  electricity.  Use it on the two tendrils that drop from the ceiling,  then blast the seed core.  Land your ship on the Pirate Homeworld, at  the Command Centre, and save.

Then head to the room called “Command  Station” on your map.  When you get there, there will be a huge thing  at the back of the room, on the floor.  It is covered with blue  crystals.  Lock onto the eye-like part and use your hyper grapple.   Then go through the door, activate the train the way you normally do,  then ride it.  When you get to the other end, go through the door and  follow the spiralling ramp on your left up to the top.

There is a  small grate on the floor to your right, so bomb it and go in in morph  ball form.  Then drain the force field using the switch in front of  you.  Step into the hologram you just uncovered, then go to the  circular panel in front of you and press A to find out that you need  access codes to get the Leviathan to open the wormhole you and the  federation want.  Go back the way you came, and then head to your ship  and fly to Norion.
