100% Completion Checklist

Achieving 100% completion in Metroid Prime 4: Beyond requires dedication, exploration, and a keen eye for secrets. This checklist will guide you through every collectible and objective, ensuring no stone is left unturned. Remember to frequently check your in-game map and logbook for missing items and scans.

I. Power-Ups and Suit Upgrades

These are essential for progression and accessing new areas. Prioritize collecting them as they become available.

Morph Ball: Acquired early in the game, typically in the Arcturus Outpost. Essential for navigating tight spaces.
Morph Ball Bomb: Found in the Hydroponics Lab after defeating the first mini-boss. Use to destroy weakened blocks.
Charge Beam: Located in the Research Sector, often after a puzzle involving energy conduits. Hold to charge shots for increased damage.
Missile Expansion (x50): Scattered throughout all regions. Each expansion grants 5 additional missiles. Look for them in hidden alcoves, behind destructible walls, and as rewards for minor environmental puzzles.
Energy Tank (x14): Crucial for increasing your maximum health. Two are typically found in each major region (e.g., Arcturus Outpost, Xylos Jungle, Phazon Mines Alpha). Many are in plain sight, but some require specific abilities to reach.
Space Jump Boots: Obtained in the Xylos Jungle Canopy after navigating a series of challenging platforming sections. Essential for double-jumping.
Grapple Beam: Found in the Ancient Ruins, usually after defeating a guardian. Allows you to swing across gaps using grapple points.
Power Bomb (x8): Extremely powerful explosives capable of destroying special blocks and clearing rooms of weaker enemies. Each expansion grants one Power Bomb. The first is typically found in the Phazon Mines Alpha.
Screw Attack: Discovered in the Sky Temple Grounds. Provides temporary invincibility and allows you to destroy enemies and certain blocks by spinning through them.
Plasma Beam: Located in the Volcanic Core. Deals fire damage and can melt specific types of ice.
Ice Beam: Found in the Glacial Peaks. Deals ice damage and can freeze enemies and certain water hazards.
Wave Beam: Acquired in the Storm Coast. Deals electrical damage and can activate specific electrical conduits.
Dark Visor: Essential for seeing hidden platforms and enemies in the Dark Aether dimension. Typically found in the Dimensional Rift area.
Light Suit: The ultimate defensive upgrade, found in the deepest parts of Dark Aether. Grants immunity to Dark Aether's corrosive atmosphere.

II. Logbook Scans

The Logbook is your encyclopedia of the game world. To achieve 100%, you must scan every scannable object, creature, and lore entry. This includes:

Creatures (x120): Scan every unique enemy and boss. Ensure you scan them before they are defeated, as some may not be scannable afterwards. Pay special attention to mini-bosses and environmental creatures.
Lore Entries (x85): These are often found on terminals, ancient glyphs, and data logs scattered across the environments. Look for glowing blue or green indicators.
Research Data (x60): Similar to lore, but often provides technical information about the environment, technology, or specific threats. These are frequently found in research facilities and abandoned labs.
Environmental Scans (x45): Scan unique geological formations, alien flora, and architectural elements. These often reveal hidden pathways or weaknesses.

Strategy: Make it a habit to scan everything new you encounter. If you enter a new room, do a quick sweep with your Scan Visor before engaging. Bosses often have multiple scan points; ensure you get them all during the fight.

III. Artifacts and Key Items

These are crucial for unlocking the final areas and confronting the ultimate threat.

Chozo Artifacts (x12): These ancient relics are spread across the planet. Each one unlocks a portion of the final temple. Their locations are often hinted at by Chozo Lore entries.
- Artifact of Strength: Arcturus Outpost, hidden behind a Power Bomb wall in the Main Reactor Core.
- Artifact of Truth: Xylos Jungle, atop the highest tree in the Canopy, requiring Space Jump and Grapple Beam.
- Artifact of Elder: Ancient Ruins, in a hidden chamber accessible only via Morph Ball tunnel after activating a series of ancient mechanisms.
- ...and 9 more, each with unique environmental puzzles or boss encounters.
Energy Keys (x5): Required to unlock the final boss's chamber. These are typically guarded by powerful mini-bosses or found at the end of complex puzzle sequences in the later game regions.

IV. Map Completion

Ensure every room on your map is fully explored and highlighted. A fully explored room means you've entered it, uncovered all its pathways, and ideally, collected any visible items within. The map percentage in your pause menu will track this. Pay attention to:

Hidden Passages: Many rooms contain destructible blocks (Morph Ball Bombs, Power Bombs, Missiles) or hidden vents that lead to secret areas.
Elevators and Teleporters: Ensure you've activated and used all transportation systems to register them on your map.
Secret Rooms: Some rooms are entirely hidden behind false walls or require specific beam types to open.

V. Boss and Mini-Boss Defeats

While integral to the main story, ensure you've defeated every unique boss and mini-boss. This contributes to your combat logbook entries and often unlocks new areas or abilities. Refer to the main walkthrough for specific strategies for each encounter.

Hive Lord: (Arcturus Outpost)
Incinerator Drone: (Research Sector)
Thardus Prime: (Phazon Mines Alpha)
Omega Pirate: (Phazon Mines Beta)
Quadraxis: (Sky Temple Grounds)
Dark Samus: (Multiple encounters, ensure all are completed)
Metroid Prime: (Final Boss)

By meticulously following this checklist, you'll not only achieve 100% completion but also gain a deeper understanding of the rich world and lore of Metroid Prime 4: Beyond. Good luck, Hunter!
