Bold truth: Metroid Prime 4’s Sol Valley and Fury Green sections finally come together to reveal the true scale of Samus’s mission—and the path to unlocking the game’s ultimate power. But here’s where it gets controversial: you’ll need to chase rare parts, grind Green Energy Crystals, and outsmart a few stubborn minibosses just to access the final upgrades. If you’re up for a thorough, beginner-friendly walkthrough that preserves every key beat, you’re in the right place.
Overview
This guide provides a comprehensive, 100% walkthrough for Metroid Prime 4: Beyond, focusing on Sol Valley and Fury Green as you gather the last Mech Parts, reclaim the Teleporter Chip, and harvest Green Energy Crystals to produce the Memory Fruit and unlock the Legacy Suit. Expect detailed notes on where to find every Mech Part, how to defeat the Behemoth miniboss, and strategies for maximizing crystal collection with practical tips and examples.
Key objectives
- Return the Teleporter Chip to Myles after reclaiming it from Corporal Reger Tokabi, then have Myles fix the Mech in Fury Green using six Teleporter Patches placed only on Mech Parts.
- Locate the five Mech Parts within Sol Valley’s Galactic Federation Debris sites and the final pieces in Flare Pool, then deliver them to Myles.
- Collect Green Energy Crystals from Lamorn Shrines and Gibardaum ore boulders to fill the Memory Fruit meter and unlock the Legacy Suit.
Step-by-step walkthrough
1) Fury Green – Teleporter Chip and early rewards
- After finishing the Great Mines, head to the Fury Green reflection sequence to retrieve a Teleporter Chip from Corporal Tokabi if you haven’t yet.
- Return the Teleporter Chip to Myles. He will craft six Teleporter Patches that you can place exclusively on Mech Parts to fix the large Golem Mech in Fury Green, enabling a pivotal strike against the force field blocking Chrono Tower.
- While you’re on this leg, pick up two additional collectibles: a Missile Expansion in the Reflection Chamber and a Psychic Power Bomb Expansion in the Quiet Clearing after destroying a Lamorn Statue with a Power Bomb.
2) Sol Valley – Mech Parts hunt
- You’ll need five Mech Parts from Sol Valley’s Debris sites plus the ones found elsewhere. Each site contains leverage points you can scan, shoot, or manipulate with your abilities to extract a patch or part.
- Western G. F. Debris Site: Pull a large Federation transport vehicle free using Psychic Lasso to reveal a Mech Chassis for a Teleporter Patch.
- Western G Fed Debris Site: Lower an antennae with a Control Beam, creating a Grapple Node to access a Missile Expansion.
- Entrance to Ice Belt: Tokabi’s trail leads to a Psychic Power Bomb Expansion after chatting with him near the Ladder of Thought Shrine.
- Northern G. F. Debris Site: Break a Mech Part from a dangling section, then shoot a Mech Forearm to release a Teleporter Patch; scan the interior for a Missile Expansion.
- Eastern G. F. Debris Site: Use a Grapple Point to reach a Denzium pod that yields a Psychic Power Bomb Expansion; another pod holds a Golem Power Cell that you’ll need to collect via a later Behemoth encounter.
- Southern G. F. Debris Site: Acquire a large helmet plate Mech Part, a Teleporter Patch, and a Missile Expansion after navigating a shutter and a Morph Ball route.
- Volt Forge detour: Tokabi’s final interaction yields a Missile Expansion as you approach the western ridge.
3) Flare Pool – Final Mech Part and final boss prep
- The last Mech Part is tucked away in Flare Pool’s Scrapyard area. Grab a Save Station, destroy scrap containers with a Psychic Power Bomb to reveal a Spider Rail, and climb to a Shot Expansion.
- Traverse the Lava Lake Bridge, blast ore blocks to access a new door, then use a maintenance hatch to reach the Charged Particle Cannon Mech Part after defeating the Behemoth miniboss.
- Behemoth miniboss: target its four eyes with your beam or Ice Shot while dodging a torrent of fire. Free energy and ammo after destroying each eye, then detonate the Particle Cannon Mech Part to finish the fight and send it to Myles.
- After Behemoth, pursue a final Lava Works Power Bomb Expansion by using a Lava Pressure Control Terminal to stop lava flow and reach the last collectible—the Psychic Power Bomb Expansion.
4) Harvest Green Energy Crystals for the Memory Fruit and Legacy Suit
- Return to Base Camp with all Mech Parts accounted for; begin filling the Altar of Legacy with Green Energy Crystals to craft the Memory Fruit.
- You don’t need every crystal in the game to finish; focus on Lamorn Shrines in the valley to gather large crystal stores. The Memory Fruit will unlock the Legacy Suit, a powerful shield-improving upgrade that consumes Missile Ammo for temporary protection.
- If you want a smoother grind, consider the Gibardaum ore boulders scattered around Sol Valley. A Power Bomb detonates these rocks into massive crystal yields, giving you big boosts in a single blast.
Helpful tips and notes
- The Crytal Radar upgrade (Green Energy Crystal Finder) is earned after filling roughly 3/4 of the memory fruit meter. It highlights nearby crystals, helping you plan efficient routes.
- The Amiibo-based Metroid Prime 4 Samus figure can unlock a desert radio jukebox for your Vi-O-La Bike, but this feature is Amiibo-exclusive and not unlockable by normal gameplay alone.
- You don’t have to collect every crystal, but achieving near-completion is advantageous for upgrading quickly and lowering the grind later. The main reward for over-collecting is extra concept art in the Main Menu Gallery.
Controversial angle and closing prompt
Some players argue that the required grind for Green Energy Crystals makes the late game feel grind-heavy and could be off-putting for newcomers. Do you think the trade-off—rich upgrades versus extended farming time—is worth it for the endgame power of the Legacy Suit? Share your thoughts in the comments: Would you skip optional crystals to hasten the push toward Chrono Tower, or embrace the full scavenger hunt for the Memory Fruit and its ultimate payoff?
Final note
All three main objectives—assembling the Mech Parts, acquiring the Teleporter Patch set, and harvesting Green Energy Crystals to unlock the Memory Fruit and Legacy Suit—are complete. You’re at the point of no return, ready to assault Chrono Tower with Betsy repaired and ready to roll.
