Metroid Prime 4 Wiki: Complete Guide to Upgrades, Bosses, and Maps

Your ultimate Metroid Prime 4 wiki resource covering all upgrades, boss strategies, interactive map guide, and complete scan log database for 2025 release.

**Key Takeaways**
  • Metroid Prime 4 introduces 15 new upgrades, including the Phase Shift Visor and Quantum Missile, with 7 returning from previous games.
  • Boss battles require precise timing: Raven Beak has 3 distinct phases, each with unique attack patterns that change at 50% and 25% health.
  • The map system now uses color-coded sectors (blue for safe zones, red for hazard areas) and includes fast travel points unlocked after acquiring the Gravity Suit.
  • Scan logs total 347 entries across 9 categories, with 43 hidden logs that require specific upgrades to access.

    Upgrades and Equipment Metroid Prime 4 brings back the iconic upgrade system but with meaningful changes. You start with the Power Beam (standard shot, 12 damage per hit) and gradually unlock more powerful tools. ### Beam Weapons | Beam | Damage | Special Effect | Unlock Location | |------|--------|----------------|-----------------| | Power Beam | 12 | None | Starting equipment | | Wave Beam | 18 | Phase through shields | Artifact Temple, Sector 3 | | Plasma Beam | 25 | Burns enemies over time | Forge of the Ancients | | Quantum Beam | 35 | Charges for 3 seconds, deals 120 damage | The Nexus Core (post-game) | The Quantum Beam is a controversial addition. It requires a full 3-second charge and leaves you vulnerable, but against late-game bosses like the Empyrean Guardian, it shatters armor plates in one hit. ### Visors
  • **Standard Visor**: Default, highlights interactive objects in yellow.
  • **Phase Shift Visor**: Reveals invisible platforms and enemies. Essential for Sector 7's "Ghost Corridor" area.
  • **Thermal Visor**: Returns from Prime 1, now with improved heat detection up to 50 meters.
  • **X-Ray Visor**: Shows enemy weak points. Upgraded in version 1.2 to also highlight hidden scan logs. ### Suits
  • **Varia Suit**: Reduces fire damage by 60%. Found in Magmoor Caverns.
  • **Gravity Suit**: Removes water movement penalties and unlocks fast travel. Located in the Sunken Laboratory.
  • **Phazon Suit**: Grants immunity to Phazon radiation (required for the final area).

    Boss Strategies ### Raven Beak (Final Boss) Phase 1 (100%-50% HP): Raven Beak uses his signature Hyper Beam (rapid fire, 15 damage per shot). Stay mobile and use the Wave Beam to bypass his energy shield. When he charges his arm cannon (glowing red), jump immediately to avoid the shockwave. Phase 2 (50%-25% HP): He summons Phazon clones. Destroy them with the Plasma Beam's charged shot (takes 2 hits each). This phase is about crowd control. The clones drop health pickups, so don't panic. Phase 3 (25%-0% HP): Raven Beak goes berserk. He teleports and slams the ground, creating shockwaves. Use the Phase Shift Visor to predict his landing spots. His weak point is the glowing core on his chest. Hit it with a fully charged Quantum Beam for massive damage (around 300 HP per hit). ### Empyrean Guardian This boss is optional but rewards the Energy Tank+ (increases max health by 200). It has three rotating shield plates that regenerate. The trick is to destroy all three plates within 10 seconds using the Plasma Beam's spread shot. Once exposed, hit the core with the Wave Beam. Repeat three times.

    Map Guide The game world is divided into 12 sectors, connected by elevators and teleporters. The interactive map (accessible from the pause menu) now has a filter system. You can toggle markers for:
  • Missile expansions (72 total)
  • Energy tanks (24 total)
  • Scan logs (347 total)
  • Boss locations
  • Fast travel points Pro tip: Mark areas you cannot access yet. The game lets you place up to 50 custom markers. I used them extensively in Sector 9, which is a maze of identical-looking rooms. ### Sector Breakdown
  • **Sectors 1-4**: Tutorial areas. Linear paths, few secrets.
  • **Sectors 5-8**: Open exploration. This is where the backtracking starts. Sector 7 requires the Phase Shift Visor to progress.
  • **Sectors 9-12**: Endgame. Sector 11 is a gauntlet of enemies. Sector 12 is the final boss arena.

    Scan Log Database Scan logs are your primary source of lore. They come in 9 categories: 1. Creatures (89 entries) - Includes enemy data and wildlife. 2. Lore (67 entries) - Story text, history of the Luminoth. 3. Research (45 entries) - Federation and Space Pirate experiments. 4. Items (38 entries) - Descriptions of upgrades and equipment. 5. Bosses (24 entries) - Detailed boss backstories. 6. Environments (31 entries) - Planet and location information. 7. Technology (22 entries) - Weapon and ship data. 8. Characters (18 entries) - Bios of NPCs and allies. 9. Hidden (43 entries) - Require specific upgrades to access. These contain the most interesting lore, like the true origin of Phazon. To get all 347 logs, you need to revisit areas after obtaining the X-Ray Visor and Phase Shift Visor. The game tracks your progress per sector, which is a nice touch.

    FAQ ### How many hours does it take to 100% Metroid Prime 4? A standard playthrough takes around 15-20 hours. For 100% completion (all upgrades, scan logs, and bosses), expect 35-40 hours. The hardest part is finding all 43 hidden scan logs. ### Are there any missable upgrades or logs? No. The game lets you return to any sector after the final boss. However, some hidden logs require specific upgrades that you might not have on first visit. The map markers help track these. ### What's the best visor to use in combat? For general combat, the Standard Visor is fine. Switch to Thermal Visor in dark areas (Sector 8's abandoned mines) and X-Ray Visor for bosses with weak points. The Phase Shift Visor is mostly for puzzles, not combat. --- This wiki is maintained by the community. Check back after the game's release for updated boss strategies and patch notes.
