Missile Launcher

Samus' trusty Missile Launcher grants her explosive projectiles more potent than her regular Power Beam fire. The Missile Launcher itself comes equipped with five Missiles, while every other Missile Expansion found increases your payload by a further five. Refer to the Missile Locations section for more details.

Press Y to fire missiles. If you lock onto an enemy before firing, your projectile will home in on the target. Also use Missiles to destroy objects containing Brinstone and to dismantle red blast-shielded doors.

Found in: GFS Olympus (Munitions Storage)

The Missile Launcher awaits aboard the Olympus in the Munitions Storage chamber. Scale the vast Repair Bay A chamber and the enter the small chamber to find it waiting inside.

Grapple Lasso

Your first Grapple Beam addition, the Grapple Lasso allows Samus to attach the beam to smaller objects such as blast shields and portable infantry shields to promptly tear them from their mounting or owner. Look for gold shimmering objects and lock onto the C icon before deploying the beam by casting the Nunchuk forward. Pull the Nunchuk back to tear the object away.

Found in: Norion (Docking Hub Alpha)

You can't miss the Grapple Lasso - find it inside a small chamber right after landing on Norion. Open the door by shooting the red lock switch.

Phazon Enhancement Device (PED) Suit

With her body self-generating Phazon, the Phazon Enhancement Device (PED) Suit allows Samus to tap into these reserves and turn the potent substance into a deadly weapon. Mastering use of the PED's Hypermode is key to your victory, so check out the Hypermode Guide for more details.

Found in: GFS Olympus (MedLab Delta)

You'll receive the PED Suit automatically after Samus awakens from her month-long sleep following the Pirate attack on Norion. This gift from the Federation will remain with her throughout the rest of the game, so be sure to accustom yourself with the ins and outs of Hypermode.

Grapple Swing

As the name suggests, the Grapple Swing allows Samus to swing from Grapple Points scattered throughout environments. Just like in previous Prime titles, lock onto the C icon above a Grapple Point and cast the Nunchuk forward to latch on and swing around. Keep in mind that while swinging Samus can continue to fire her weaponry.

Found in: Bryyo (Reliquary I)

From the giant Gateway chamber, open the sealed door by releasing both locks and make your way through to the Grand Court. Conquer the pair of Reptilicus Hunters ambushing you there and move through to the Hillside Vista.

Make your way to the opposite cliffside via the tunnels along the wall (use the Snatchers to traverse the tunnels, but watch out for the Korba).

Use the Grapple Lasso and a Missile to dismantle the statue covering the door you find, then simply step inside the chamber to discover your prize waiting inside.

Ice Missile

Rather than your standard Ice Beam, Ice Missiles take center stage as Samus' ice-powered projectiles. Use Ice Missiles to freeze targets in their tracks (some foes need a few shots to slow them down), and dismantle white blast shields with a single Ice Missile.

Found in: Bryyo (Bryyo Fire - Temple of Bryyo)

You'll need to conquer Rundas in the Temple of Bryyo to secure this upgrade. Refer to the bosses guide for tips to win this upgrade.

Ship Missile

Samus' gunship can only go so far without ballistic capabilities. With the Ship Missile upgrade, Samus can command her ship (via the Command Visor) to perform bombing runs on fortified objects from shield generators to massive blockades. She can also summon her ship to lay down ordnance on hostile targets in open areas.

Initially upon receiving this upgrade you'll begin with three Ship Missiles in your arsenal, but can expand that number up to 11 by locating Ship Missile Expansions. Check the Ship Missile Locations for details on where to find them all.

Found in: Bryyo (Hangar Bay)

Upon securing the Ice Missile upgrade, head to the downed GF frigate and make your way through the Falls of Fire by freezing the Fuel Gel spouts along the chasm. Explore the regions beyond, move through the Hidden Court area and up the Ruined Shrine to ultimately find yourself at the Hangar Bay.

At first glance the area seems completely deserted, but step towards the lift in the corner of the chamber or the Missile upgrade terminal to see otherwise. Repel the Reptilicus Hunter invasion to secure the area and bring the systems back online.

First things first, you'll need to open up the hangar bay door to allow your ship to enter. Even though your ship isn't present, raise the upgrade station by way of the terminal beside the landing pad. Ride up the lift in the corner to the top of the damaged platform, then leap across atop the raised upgrade station.

Make your way over to the command station by way of the Grab Ledge (and extend a platform with the Grapple Lasso). Once inside, activate the terminal to open up the hangar doors. Then simply scale back down to ground level, lower the upgrade station, summon your ship then hit the switch again to receive the Ship Missile upgrade.

Hyper Ball

The Hyper Ball adds a potent Morph Ball Hypermode attack form. While in Hypermode, simply hold A when in Morph Ball mode to unleash a continuous electrical Phazon attack to automatically injure anything close by. Certain Phazon growths in the environment can only be eliminated with this attack.

Found in: Bryyo Seed (Bryyo Leviathan Core)

Defeat the monstrous Mogenar in the heart of the Bryyo Seed to receive this upgrade. Refer to the bosses guide for tips to survive the heated battle in one piece.

Boost Ball

The trusty Boost Ball upgrade performs exactly as it has throughout the Prime series. Capable of boosting Samus around at higher speeds while in Morph Ball mode, hold B to charge the device and release to send Samus on her way. Use the Boost Ball to activate Spinner devices, charge up inactive Kinetic Orb Cannons and ascend half-pipes in the environment with ease (boost as you land in the pipe and accelerate towards the opposite side to build vertical momentum).

Found in: SkyTown (Ballista Storage)

You'll need to face and defeat the frenetic Defense Drone in the Ballista Storage chamber to score this upgrade. Upon discovering Ghor's powered-down armour suit on the Spire Pod, head right and continue in that direction to eventually locate the Ballista Storage area (and the Boost Ball before it's promptly snatched away from you). Refer to the bosses guide for tips to shut the drone down to score your prize.

Plasma Beam

With the stacking nature of beam weapons in Metroid Prime 3, the Plasma Beam's primary fire combines with the Power Beam to deliver long lances of super-heated energy capable of melting most targets. Along with its potent attack power, use the Plasma Beam to open orange doors, repair damaged circuit panels and melt damaged debris.

Found in: SkyTown (Main Docking Bay)

You must stop Ghor's rampant behaviour to score the Plasma Beam. Upon watching the short skirmish between Ghor and Samus below Aurora Unit 217's chamber, quickly return to your gunship at the Main Docking Bay to find the weirdo doing a number on your ride. Step outside to face him in a final showdown. Refer to the bosses guide to learn a few tips to bring the hunter to an unfortunate end.

Screw Attack

The Screw Attack upgrade allows Samus to cross otherwise inaccessible horizontal regions with ease. She can also utilise Wall Jump surfaces to scale tall shafts. As it has throughout the Metroid series, while active the Screw Attack generates deadly energy around Samus to protect her from any hostiles wandering into her flight path.

Activate the Screw Attack by holding forward and pressing B again after performing a Space Jump. Press B repeatedly up to five times to keep Samus in the air as she travels horizontally (experiment with timed jumps to extend her flight distance). Screw Attack into a Wall Jump surface and continuously press B to scale vertical shafts with ease.

Found in: Bryyo (Bryyo Ice - Hall of Remembrance)

Thankfully this time you'll discover the Screw Attack early in the game. Upon defeating Ghor and scoring the Plasma Beam, you'll eventually discover a tall shaft lined with Wall Jump surfaces leading to the SkyTown East tram. With no way of scaling the shaft, Aurora Unit 217 will suggest backtracking to Bryyo in search of new items. So let's do just that. Return to Bryyo and land at the Fiery Airdock.

Head for the Main Lift chamber and use the Snatchers deep inside the narrow tunnels to reach the second floor. Once there, you may remember spotting a tunnel fashioned in the shape of a lizard's open mouth filled with frozen ice. Use your Plasma Beam to clear the obstructions and roll through to find a hidden room beyond. Step inside to discover a large round chamber inhabited by a huge frozen battering ram in the ceiling and a lone inactive stone Golem.

First melt the ice around the battering ram before using a Morph Ball Bomb to activate the Golem. The Golem will promptly slam the object into a huge gong, summoning a Spinner device. Use the Spinner to rotate the chamber's walls to reveal a cracked wall. Activate the Golem again and watch as it uses the battering ram to crash through the weakened wall.

Step into the newly revealed chamber and enter the teleporter to find yourself in a truly alien environment to the rest of Bryyo. Explore around to eventually find the Screw Attack waiting in the grand Hall of Remembrance.

Ship Grapple

The second and final upgrade for Samus' gunship, the Ship Grapple grants the gunship its very own Grapple Beam capable of lifting ridiculously large objects several times the gunship's own weight and size. Simply use the Command Visor to summon your ship to lift objects possessing Ship Grapple Points. Note that if you summon the ship to a landing pad while it's carrying an object, the object will be returned to its original location.

Found in: SkyTown (Eastern SkyTown - SkyTown Federation Landing Site)

Upon arriving at SkyTown East, explore the area and pass through the Chozo Observatory and over Skybridge Athene to eventually locate the SkyTown Federation Landing Site. Aurora Unit 217 will summon a Bomb Slot, activate it to lower the shutters blocking the landing pad. See the small terminal overlooking the landing pad? Summon your ship and simply activate the terminal to receive the Ship Grapple upgrade.

Seeker Missile

The Seeker Missile upgrades Samus' Missile Launcher with a ballistic delivery system capable of launching up to five missiles at once. Hold Down on the D-Pad to engage the system, then simply wave the targeting reticule over single or multiple targets to line each one up, then release to send your payload on its way. Use this effective weapon to strike multiple targets all at once, and use it to dismantle objects and doors sealed with several locking pods.

Now normally as you engage the Seeker Missile you'll waste a single missile in the process. Oddly enough, if you activate the Scan Visor, hold Down on the D-Pad, then press Minus to return to the Combat Visor, Samus will engage the Seeker Missile's targeting reticule without firing a missile first.

Found in: SkyTown (Eastern SkyTown - Xenoresearch B)

Soon after upgrading your ship and receiving the Ship Grapple you'll find yourself inside a chamber filled with the husks of Space Pirate foes. You know what that means. Continue to explore the area to discover corridors lined with dozens of Phazon Metroid specimens, all itching to get their pincers on you.

Eventually you'll discover the power source of this area, an Energy Cell locked inside a station beside a containment pod containing the Seeker Missile. Use the Grapple Lasso to tear off the cover on the Energy Cell, then extract it to power down the containment pod's force field.

Simply fire a Missile at the pod to breach the glass and gain access to your prize.

Hyper Missile

The Hyper Missile adds ballistic capabilities for Samus in Hypermode. Simply fire a Missile while in Hypermode to deliver an incredibly powerful blast of Phazon. Don't blindly fire it around too much though as each blast significantly drains your Phazon meter. Large spiky growths of Phazon can be destroyed by a single Hyper Missile or two.

Found in: Elysia Seed (Elysian Leviathan Core)

Defeat Helios in the core of the Elysian Leviathan Seed to receive the Hyper Missile (and a dose of corruptive Phazon). Refer to the bosses guide for tips to shut the rogue droid and its Swarmbot cronies down.

X-Ray Visor

Combining the Thermal Visor and X-Ray Visor from Metroid Prime, Metroid Prime 3's X-Ray Visor grants Samus an effective night-vision apparatus along with the ability to detect high concentrations of Phazon (notice the bright glow from Samus' bones). Hold Minus and point at the lower-left corner of the screen to activate the visor.

You'll find plenty of use for the X-Ray Visor. Use it in tandem with the Nova Beam to penetrate Phazite shields and strike the glowing Phazon cores of foes such as Phazon Metroids, Commando Pirates and Berserker Knights. The X-Ray Visor can also reveal the location of any enemy capable of cloaking itself. Finally, use the X-Ray Visor to access certain interface terminals otherwise inaccessible. Take note however that Hypermode-enabled enemies in close proximity will wreck static havok on the X-Ray Visor.

Found in: Pirate Homeworld (Pirate Command - Command Vault)

Travel to the Command Courtyard and disable the ventilation fans by extracting the Energy Cell directly above the fans. Roll through the ventilation tunnels to discover the Command Station - carry on through here to discover the Command Vault area where the X-Ray Visor awaits. Look up - see the five orange pods above? Simply use the Seeker Missile to strike all pods at once, revealing the X-Ray Visor as your prize.

Grapple Voltage

The final Grapple Beam addition adds a curious feature: the ability to drain or charge terminals. Throughout the Pirate Homeworld you'll discover energy force fields powered by a nearby terminal. With this upgrade equipped simply attach the Grapple Lasso to the terminal and push forward to overload the terminal with energy, or hold back to drain the system of juice.

Certain objects and foes can also be powered/overloaded or drained, just look for the C icon to see if the Grapple Lasso works. Amazingly, you can also drain energy from grappled enemies to restore your own health (in small amounts).

Found in: Pirate Homeworld (Pirate Research - Proving Grounds)

Defeat Gandrayda in battle to receive this Grapple Beam addition. First pick up the map of the Pirate Homeworld at the Lift Hub to reveal the Pirate Research area. Fly your ship there and explore the region to ultimately discover Gandrayda disguised as a Federation Marine. Refer to the bosses guide for tips to survive the showdown with Dark Samus' final puppet.

Spider Ball

The Spider Ball completes Samus' Morph Ball mode functionality. With this upgrade equipped Samus can attach to magnetic rails while in Morph Ball mode to access otherwise inaccessible regions.

Simply hold Z to attach to a magnetic rail and move around freely. While holding Z, lay a bomb to propel Samus off the track. Also use the Boost Ball to launch Samus away from the track on a perpendicular vector to reach adjacent tracks or distant platforms.

Found in: SkyTown (Powerworks)

Upon securing the Grapple Voltage you'll be clear to locate the Spider Ball. Return to Elysia and set down at Landing Bay A. Travel to the Junction area and head south. Beyond you'll discover an elaborate gate system blocking access to a Zipline Cable. Simply attach the Grapple Lasso to the gate and deliver enough energy into the device to release the lock and move the gate out of your path.

With your path clear, ride the Zipline Cable along till it malfunctions and drops you off on a platform halfway along. Look towards the structure beyond the drop and Screw Attack across to make the distance. Head inside and roll down into the main chamber of the Powerworks. Here you'll discover a tall pillar in the centre below a set of rotating gears in the ceiling.

Look closely, see the fallen cog on the ground? Stand atop the raised platform nearby and look down at the cog. Deploy the Grapple Lasso and pull back to launch the cog into the air. Quickly lock on as it spins and fire a Missile to snugly send it back into place among the other gears. With the system operational again the pillar will open wide, revealing the Spider Ball within the grasp of an elaborate Chozo statue.

Hazard Shield

With the Hazard Shield equipped Samus can safely traverse hostile and caustic environments without harm. She'll be able to pass through regions on the Pirate Homeworld under constant acid rain bombardment without a scratch, and can wade through formerly-dangerous Fuel Gel pools on Bryyo.

Found in: Pirate Homeworld (Pirate Research - Craneyard)

You'll need the Spider Ball to successfully find your way to the Hazard Shield. Head to the Pirate Research region of the Pirate Homeworld and back to the Craneyard area. Look for a tall Spider Ball track running up a wall and follow it along. You'll eventually find yourself inside a snug compartment below the giant central structure outside in the deluge of acid rain. Use the two Spinners present to rotate the pair of rotating sections of the structure to line up a clean passage up to the top (be sure to grab the Missile Expansion hiding up over on the right of the structure).

See the tunnel up on the left side leading away from the structure? Line up the rotating tunnels to create a clear path up there, then climb up and move through to find yourself inside a small command alcove overlooking the Craneyard. Simply activate the lone terminal there to summon the Hazard Shield to your position.

Nova Beam

The Nova Beam adds to Samus' arm cannon a glowing green energy blast capable of penetrating objects composed of Phazite. Used in tandem with the X-Ray Visor, objects hidden behind Phazite shields or armour can be struck flawlessly with each shot. Also use the Nova Beam to open green doors.

Found in: Pirate Homeworld (Pirate Mines - Main Cavern)

You've got a long journey ahead to the Nova Beam. Head to the Mining Site of the Pirate Homeworld and explore the region to ultimately find yourself at the Main Cavern. See the Nova Beam inside the Phazon mining chamber? You'll first need to find your way inside. Walk around the enclosure and activate the terminal on the far side to power up a nearby elevator.

Ride the elevator down and enter the chamber to face a Pirate welcoming committee. See those access hatches surrounding the chamber? A trio of Pirates will attack in waves, usually comprised of Assault Pirate Troopers and Commando Pirates. They won't stop coming, so you'll need to focus on the task at hand.

Normally the massive Phazon mining equipment will spend its time drilling the ore below the chamber, but watch out when a massive beam erupts in the center to draw up loose Phazon minerals. As it does so all your foes will scramble to grab hold of something before being sucked up into the beam. Quickly target one and fill them with enough firepower to break them loose and straight up into the beam. With the beam disrupted four odd glowing objects appear below the Nova Beam's pod. Quickly target one and shoot it before they retract.

Hold out till the beam begins sucking everything towards itself again and send another hapless Pirate straight into it (use Hypermode to avoid taking too much damage in the crossfire). Shoot down another of the red objects and repeat the sequence till all four objects blow. With all targets down the Nova Beam will plummet to ground level; leaving you clear to claim your prize.

Hyper Grapple

This final Phazon-powered ability enables Samus' Grapple Voltage while in Hypermode. Simply attach the Grapple Lasso to a target while in Hypermode and hold forward to deliver energy towards the target to overload it with excessive Phazon energy. Certain Phazon growths can only be destroyed by overloading them with energy from the Hyper Grapple.

Found in: Pirate Seed (Pirate Homeworld Leviathan Core)

Send Omega Ridley to oblivion deep inside the Pirate Homeworld Seed to receive your final suit upgrade. Refer to the bosses guide for tips to score victory against yet another form of Ridley.
