Metroid Prime 3: Corruption Walkthrough: Missile Expansions

Here you’ll find the location for every Missile Expansion in Metroid Prime 3: Corruption, as well as detailed explanations on how to get them and what powerups you’ll need. Expansions have been listed in order of when you can pick them up during the game. For a list of expansion by area, click here.

It’s worth noting that in Metroid Prime 3, there’s a room in Eastern SkyTown called the Chozo Observatory that, when you activate the numerous bomb slots in the room, will send satellites into the sky, giving you the item locations for every expansion in the same! The Expansions will appear as white dots on the map, giving you nothing more than that to go off of. As a caution: any items on the G.F.S. Valhalla will NOT show up on your map!

 


Missile Expansion #1

Location: Munitions Storage, G.F.S. Olympus

Requirements: None

You’ll pick up this first Expansion as part of the progression of the game. Simply walk into the room and grab it.

 


Missile Expansion #2

Missile Expansion #3

Location: Grand Court Path, Bryyo Cliffside

Once you near the end of the path, turn around and you’ll see a statue that contains Gel Fuel sitting on a ledge about halfway up the wall behind you. Shoot it, and after it explores, jump up to the ledge and follow the path to grab this Expansion.

 


Missile Expansion #4

Location: Hillside Vista, Bryyo Cliffside

Requirements: None

After restoring power to the ship in the Crash Site, head back outside and roll into the Morph Ball tunnel. Navigate your way upwards, avoiding the lasers and pulling a double bomb jump (this is easier than ever thanks to the Spring Ball ability, where you can flick your controller upwards and Samus will Jump in Morph Ball form) to get to the top of the ship. Once there, the Expansion will be waiting for you in plain sight.
