Finding all of Metroid Prime 4: Beyond‘s missile expansions is a task that spans the entire game. You can get some early on, but most require upgrades like the Spider Ball or Grapple Hook that remain out of reach until late in the game. Expect to backtrack quite a lot if you want to finish up with all 48 missile expansions, which is a good idea. Missiles deal heavier damage than even the upgraded power beam, and once you unlock super missiles, each of those consumes five regular missiles.
Below, we show you where to find all the missile expansions in Metroid Prime 4 and how to get them. We’ve listed them roughly in the order in which you can expect to acquire them and detailed which upgrades you’ll need to get them.
Fury Green missile expansions
Half of Fury Green’s missile expansions are locked behind upgrades, but you can still grab a few before leaving this region for the first time.
Grove of the Sacred Tree
After getting the missile launcher and rescuing Miles, you’ll come across two amber obstacles in the Grove of the Sacred Tree. Behind one is a door and behind the other is this expansion.
Broken Hall
You’ll enter the Broken Hall area after defeating Carvex. Drop a ball bomb next to this cluster of roots to access the missile expansion.
Resin Creek
A large, orange fruit blocks this missile expansion. Jump while in morph ball form (by pressing the Y button) and lay a bomb or place a psychic bomb to reach it without jumping, then grab the expansion.
Cliffside Gate
Return here after acquiring the Psychic Boots, materialize the psychic platforms, and hop across them to reach this missile expansion.
Cargo Launcher
Use the Psychic Boots to climb up the platforms, and grab the expansion.
Reflection Chamber
The sturdy container behind the mech unit houses another missile expansion, but you can only destroy it with a super missile. Those remain out of reach until you clear the Great Mines, so make sure to revisit this room after that.
Volt Forge missile expansions
Volt Forge holds eight missile expansions inside, most of which are out of bounds until you get the Boost Ball and Thunder Shot.
Facility Approach
Once you arrive in Volt Forge and regain control over Samus, face the region entrance and turn around. The container on your left has an open back, and an expansion is inside.
Speed Tunnel C
Walk into the Tower 1 side of the tunnel that connects Tower 1 and Tower 3, and turn around when the tunnel opens onto the sky. Fire a controlled beam, guide it into the opening of the tube above you, avoid the robots inside, and hit the pressure plate at the back. It’ll open a hatch that gives you access to the missile expansion.
Tower 2 Receiving Lobby Archives
After booting Tower 2’s generator back up, return to the tower lobby. Enter morph ball form, and move over the ball hologram to activate a small elevator that takes you under the floor. Navigate the swirl, avoiding electrical currents, and grab the expansion at the center.
Tower 3 Certification — End
On the Certification level, just before the boss chamber door, look right. Fire a missile at the debris to clear it and reveal a container with a psychic lock. Activate the scan visor, trace the pattern to unlock the container, and swipe your missile expansion.
Loading Airlock
With Boost Ball in hand, use the spinner to swing the cargo containers around. Keep smacking the containers into each other until the one at the end drops to the ground. It’ll open, revealing an expansion and some angry robots.
Tower 1 Processing
Return here once you have the Boost Ball, defeat the enemies in the room, and activate the spinner device with the Boost Ball. Once the floor is fully raised, you can get the missile expansion.
Tower 1 Irradiation Room
This expansion taunts you from the moment you enter the room, but you need the Boost Ball to get it. At the bottom of the chamber, pull off the hatch, enter ball form, and use speed boosts to half-pipe your way up. The expansion is waiting for you at the top.
Tower 3 Certification — Lobby
Getting this one requires the Thunder Shot, the chip for which you get in Volt Forge after acquiring the grapple beam. A small generator sits in the lobby corner. Unlock it with the Thunder Shot, then keep firing electricity at it until it opens the container holding the expansion.
Flare Pool missile expansions
You’ll need upgrades for all but one Flare Pool missile expansion. Plan on revisiting this location late in the game to scoop everything up.
Volcano Entrance
Use the scan visor to manifest a trio of psychic platforms, then jump up them to find the missile expansion.
Shoreline Access
Once you have the ice shot, fire a chunk of the cold stuff to freeze the lava pillar, then enter morph ball form and jump behind it to grab the missiles.
Overseer Room
Use the scan visor to mark the panel shown above so you can use the lasso to yank it off. Activate the switch, then time a controlled shot so you can guide it to all three psychic switches before they disappear and make the missile expansion appear. If the psychic switches do vanish, wait a second and they’ll pop up again.
Ventilation Works
You need the Boost Ball and Spider Ball for this one. Use speed boosts to roll up the left side of the pipe, then grab onto the magnetic rail with ZL. Roll along to the end where the missile expansion awaits.
When you enter the room via the doorway, you’ll see a magnetic track lurking in the shadows. Use the Spider Ball to climb it, and make your way up to the missile expansion using bombs to leap from track to track while avoiding electrical bursts.
Cooling Room
Use the Thunder Shot to remove this room’s lock and to destroy the turret that springs to life when you enter, and then grab the missile expansion behind the turret.
Pressure Room
Use the Thunder Shot to unlock the door, the lasso to rip the cover plate off, and the Thunder Shot again to activate the mini-generator and power it until the missile expansion appears. You’ll also get access to a shot expansion.
Subobservation Room
Reach this room via (you guessed it) using the Thunder Shot to unlock the doors, dealing with robots and turrets as you go along. Once you reach the Subobservation Room, you’ll have to deal with several waves of increasingly strong robots. Defeat them — don’t forget you need to use a controlled shot while the vanishing robot is visible to incapacitate them — and ignore the bomb slot that activates.
On the other side of the room, use a missile to destroy a brittle covering and the lasso to pull a plate off, then enter ball form and jump up to the top. Grab the missile expansion by performing a bomb jump — lay one bomb, wait until just before it explodes and lay another. Then lay one at the top of your bounce.
Volcano Heart
The Volcano Heart area becomes accessible after you defeat Flare Pool’s boss, Phenoros, and you can get there on the Vi-O-La IC bike. Instead of entering the Ventilation Works, stay on the bike, ride over the lava, and enter the next chamber. Once inside, turn right and hug the wall. You’ll soon come across a lone missile expansion, sitting there waiting for you.
Ice Belt missile expansions
The Ice Belt scatters its eight missile expansions throughout the underground facility, and you won’t be able to get them all until you have the Thunder Shot and Spider Ball, the latter of which you obtain on a return visit to Ice Belt following the initial expedition.
Loading Crane
Pop a morph ball bomb into the bomb slot next to the cage holding the missile expansion to open said cage’s door.
Medical Bays Staging Corridor
Once you restore power to the facility and are on the way back up to the elevator, a Griever will leap out of a room in this hallway. Enter that room and transform into morph ball form, then roll into the ball passage. The missile expansion is on the other side.
Bio-Labs Access
Turn right after clearing the first TK Code lock, and use the lasso to yank the debris away and reveal the missile expansion.
Surgery Corridor
Use the lasso at the back of this room in the Medical Bays to remove a morph ball hatch, then roll into the tunnel and get the expansion.
Ancient Temple
In the room where you get the Spider Ball, look behind a broken pillar to the side of the Lamorn statue, where you’ll find this next expansion.
Bio-Labs Lobby Circuit
Enter the morph ball tunnel off the cryo-pod circuit after you get the Spider Ball, and use the swing nodules to launch Samus over the red nodes. Drop a ball bomb on the node to activate it and quickly do the same for the other one to remove the covering over the missile expansion.
Storage Bay
In the Storage Bay, where you found a TK code on the dead, frozen Griever, drop down behind the cryo-pod and enter morph ball form. Take the elevator down, then use the Spider Ball to move along the metal tracks, avoiding the monsters there, until you reach the missile expansion. You’ll need to use a ball bomb to launch Samus up so she can reach it.
Elevator Landing
Use the Thunder Shot to release the door lock, deal with the Grievers, then grab the expansion inside.
Great Mines missile expansions
Don’t worry much about missing the Great Mines expansions on your first visit. When all’s said and done, you’ll have the facility’s main elevator active again and can revisit locations with much less hassle.
Level 1 Mine Shaft Elevator
Navigate around to the back of the elevator, and use the Spider Ball to work your way around and up until you reach this expansion.
Level 2 Narrow Crevice
After you hop across the crevice, turn around to see a handful of grapple nodes. Grapple across the chasm to reach the expansion at the end.
Level 3 Transit Tunnel E
Across from the save point is a hatch you can lasso open. Enter ball form, roll through the tube, and get the expansion.
Level 2 Blast Mining
After you get the Super Missile in this room, use one to blow up the cracked wall off to the side and reveal another expansion.
Level 1 Transit Tunnel A
Use a Super Missile on the red nodes to blow open the door and get a missile expansion.
Level 2 Transit Tunnel B
Use a Super Missile on the red cluster of nodes at the top of this rubble pile to clear the debris and get access to the missile expansion behind it.
Level 2 Easing Tunnel
Return here after acquiring the Power Bomb upgrade. Use one in the bomb slot to raise the mine cart, then demolish the rubble in the cart with a Super Missile.
Sol Valley missile expansions
10 missile expansions are strewn across the Sol Valley desert, some underground, one in a shrine, and a few tucked away in Federation wreckage. We numbered them, but you can collect them in any order so long as you have the requisite upgrades.
Sol Valley expansion 1
This one is buried in the sand southwest of the Great Mines entrance. You can get it once you have the lasso.
Sol Valley expansion 2
Southeast of the entrance to Fury Green is a bit of Federation wreckage. Use a controlled shot to hit the pressure plate at the base of the spire to lower it, then use the Grapple Beam to swing across to the container upon which the expansion rests.
Sol Valley expansion 3
This one is northeast of the Volt Forge entrance, west of a Lamorn shrine. Yoink it out of the sand with the lasso.
Sol Valley expansion 4
This missile expansion is suspended in midair, and you need to use a speed boost on the Vi-O-La to reach it.
Sol Valley expansion 5
Blast the panel with a rocket to reveal a ball-shaped tunnel, then roll through it to get the expansion on the other side.
Sol Valley expansion 6
This one is underground in the Source of the Spring shrine north of Flare Pool, though you need the Thunder Shot to open it. In the main chamber, blast some crystals to reveal a morph ball passage, then roll through to get the expansion.
Sol Valley expansion 7
This one’s buried outside the entrance to Ice Belt. Use the lasso to bring it up.
Sol Valley expansion 8
Enter Ice Belt, then use the Grapple Beam to exit via the other side. You’ll pop out on a platform with a Boost Ball rail. Scan it with the visor to activate it, then boost into the portal to reach the other side and the expansion there.
Sol Valley expansion 9
Blast the wreckage inside this ruined building with a missile to reveal the expansion.
Sol Valley expansion 10
After you clear the Great Mines, Tokabi sets up camp near Flare Pool. Speak to him there, return to base camp in Fury Green to progress the story, and then travel to the location shown above to find Tokabi camping out again. Listen to his story to get this missile expansion.
