- Metroid Fusion all items routes work best when organized by sector and ability gate.
- Major upgrades unlock new rooms, doors, movement options, and optional expansion paths.
- Best cleanup point is late in the story, after Gravity Suit, Space Jump, Screw Attack, and Power Bombs.
- Most missed items are hidden behind Speed Booster blocks, Shinespark routes, and Morph Ball passages.
- Final check should happen before entering the last evacuation sequence.
Metroid Fusion All Items: How the Collection Route Works
A 100% collection run combines mandatory upgrades with optional expansions. The safest approach is to collect obvious items during the story, mark blocked rooms mentally, and return after Samus gains the movement or weapon needed to open them.
Metroid Fusion uses the B.S.L. station as a connected network rather than a simple one-way path. Navigation Rooms assign objectives, while elevators and security systems determine which sectors are available. A room that looks empty early in the game may contain an item that requires Bombs, Speed Booster, Power Bombs, or a late-game jump ability.
Do not force every suspicious room immediately. Record the obstacle, continue the story, and revisit it when a new ability clearly matches the barrier.

The official Nintendo Metroid Fusion page provides the game’s core release and platform information. For practical collection planning, use the map, item type, and ability requirement together rather than relying on a single linear walkthrough.
Step-by-Step Collection Route
Follow this order to reduce unnecessary backtracking. The route prioritizes story progression first, then groups optional item collection around the abilities that unlock the largest number of rooms.
Save after every major upgrade and before difficult Shinespark or Speed Booster puzzles. A failed attempt can reset your position even when the item itself is not permanently missable.
Collect Early Story Upgrades
Explore the opening Main Deck and Sector 1 route until Samus gains the Morph Ball and Missile Launcher. These tools provide access to narrow tunnels, missile doors, and the first expansion rooms. Collect nearby items when the route is safe, but avoid long detours before Bombs become available.
Open Bomb and Beam Routes
After acquiring Bombs and the early beam upgrades, revisit nearby rooms with suspicious floors, corners, and Morph Ball gaps. Bomb blocks often reveal alternate paths, while charged shots and missiles open routes that basic beam fire cannot affect.
Use Speed Booster for Long-Distance Items
Once Speed Booster is available, inspect long corridors in every accessible sector. Run through the full corridor, crouch to store the charge, and use a directional Shinespark to reach elevated platforms or distant item chambers.
Return with Stronger Weapons
Revisit sectors after Super Missiles, Ice Missiles, Wide Beam, Diffusion Missiles, and later beam upgrades become available. Check colored doors, armored blocks, frozen enemies, and rooms that previously ended at a weapon barrier.
Perform the Late-Game Sweep
Complete the main route until Gravity Suit, Space Jump, Screw Attack, and Power Bombs are available. Then sweep each sector from the map entrance outward, checking every vertical shaft, hidden tunnel, Speed Booster corridor, and Power Bomb block.
Recommended Cleanup Timing
| Cleanup phase | Abilities to prioritize | What to search |
|---|---|---|
| Early cleanup | Morph Ball, Missiles, Bombs | Visible tunnels, missile doors, bomb blocks |
| Midgame cleanup | Speed Booster, Super Missiles | Long corridors, green barriers, Shinespark paths |
| Late cleanup | Gravity Suit, Space Jump | Water rooms, high ledges, vertical shafts |
| Final sweep | Screw Attack, Power Bombs | Special blocks, enemy barriers, hidden chambers |
Sector-by-Sector Item Checklist
A sector-by-sector sweep prevents missed rooms and makes the final percentage easier to verify. Start at the Main Deck, then move through the six numbered sectors. If an item appears unreachable, identify the exact barrier before leaving the room.
An unexplored room is not always an item room. Prioritize isolated chambers, dead ends behind colored doors, unusual wall shapes, and corridors long enough to support a Speed Booster charge.
Main Deck
- Check elevator corridors and maintenance rooms.
- Revisit areas opened by late story events.
- Inspect vertical passages and restricted routes.
Early Sectors
- Search Morph Ball tunnels and bombable floors.
- Recheck missile and beam doors.
- Mark rooms blocked by later abilities.
Late Sectors
- Inspect water, ice, and dark rooms carefully.
- Use Gravity Suit and Space Jump for vertical cleanup.
- Finish Power Bomb and Shinespark puzzles last.
| Area | First-pass focus | Late-pass focus |
|---|---|---|
| Main Deck | Elevators, visible side rooms, mission routes | Restricted corridors, high platforms, story-opened rooms |
| Sector 1: SRX | Morph Ball tunnels, missile doors | Screw Attack paths, Speed Booster rooms |
| Sector 2: TRO | Bomb blocks, plant chambers, beam barriers | Wide Beam routes, hidden vertical rooms |
| Sector 3: PYR | Heated rooms, missile branches | Power Bomb blocks, long Speed Booster corridors |
| Sector 4: AQA | Accessible water rooms | Gravity Suit routes, submerged side chambers |
| Sector 5: ARC | Frozen passages and visible expansions | Power Bomb rooms, post-boss cleanup |
| Sector 6: NOC | Dark-room boundaries and safe routes | High ledges, frozen-enemy puzzles, late movement paths |
Room-by-Room Search Pattern
Use the same inspection pattern whenever you enter an item candidate:
- Fire at unusual walls and ceilings.
- Bomb floors, corners, and Morph Ball-height gaps.
- Check whether enemies can be frozen or destroyed to reveal a route.
- Look for a corridor long enough to activate Speed Booster.
- Use Power Bombs only after confirming that the room contains suspicious block patterns.
- Recheck isolated platforms after obtaining Space Jump.
100% Collection Check:
- Collect every mandatory beam, suit, weapon, and movement upgrade
- Search all visible Missile Tank and Energy Tank rooms
- Revisit blocked rooms after Speed Booster and Super Missiles
- Complete Gravity Suit and Space Jump underwater and vertical routes
- Use Screw Attack and Power Bombs for the final hidden-room sweep
Hard Item Rooms and Movement Techniques
The most difficult expansions usually test movement instead of combat. Practice each technique in a safe room before attempting a high-value item route. Shinespark setups are especially sensitive to timing because the stored charge disappears if Samus takes an invalid action.
For difficult rooms, first map the route without attempting the item. Learn where to run, where to crouch, and where the stored Speed Booster charge must be released.
| Technique | Setup | Typical item use |
|---|---|---|
| Bomb jump | Enter Morph Ball form and place bombs in sequence | Reaches low vertical ledges |
| Wall jump | Jump against a usable wall and redirect | Gains height in narrow shafts |
| Shinespark | Run, crouch to store charge, then release directionally | Crosses long gaps and breaks speed blocks |
| Space Jump | Chain aerial jumps with controlled direction | Reaches high platforms and isolated rooms |
| Power Bomb reveal | Activate a Power Bomb in a suspicious room | Exposes hidden blocks and passages |
Common Failure Points
Starting the Speed Booster run too late:
A corridor may look long enough but still fail if Samus begins from the wrong position. Start from the far end of the room and preserve a straight line whenever possible.
Crouching at the wrong moment:
Crouching too early can cancel the run, while crouching too late may leave insufficient time to aim the Shinespark. Use the end of the corridor as your visual timing cue.
Entering water rooms too early:
Some expansions are technically visible before Gravity Suit but are much harder to reach. Return later rather than spending resources on repeated low-probability attempts.
Ignoring the room layout:
A Power Bomb may reveal several blocks, but not every revealed opening leads to the item. Check the map and follow the newly opened branch before using another charge.
Expansion Priority
| Priority | Item type | Why it matters |
|---|---|---|
| High | Energy Tanks | Improves survival during bosses and dangerous cleanup |
| High | Missile Tanks | Supports missile doors and stronger combat options |
| Medium | Super Missile Tanks | Helps sustain late-game weapon usage |
| Medium | Power Bomb Tanks | Makes hidden-block cleanup more flexible |
| Variable | Difficult Shinespark items | Best attempted after the full movement set is available |
Final Verification and FAQ
Complete the final sweep before entering the ending route. The evacuation sequence changes normal exploration, so finish optional rooms, save your progress, and confirm the item percentage before committing to the last story objectives.
When the percentage is lower than expected, revisit the sectors with the most complicated movement rooms first: AQA water routes, PYR Speed Booster corridors, and late-game Main Deck passages.
Final Verification Table
| Check | Action | Result |
|---|---|---|
| Major upgrades | Confirm every required beam, suit, weapon, and movement ability | All progression gates are covered |
| Sector maps | Revisit isolated rooms and unexplored branches | Hidden expansion rooms are easier to identify |
| Speed Booster routes | Test long corridors from both practical approaches | Shinespark items are less likely to remain hidden |
| Power Bomb rooms | Scan suspicious blocks and dead ends | Late-game hidden paths are revealed |
| Save status | Save before the final story transition | Cleanup progress is preserved |
Q: What is the best order for Metroid Fusion all items?
Follow the story until the late-game movement set is available, then clean sectors systematically. Collect easy items early, but leave Speed Booster, water, vertical, and Power Bomb puzzles for later.
Q: Which items are most commonly missed?
The most frequently overlooked expansions are behind Shinespark routes, concealed Morph Ball passages, isolated high platforms, and Power Bomb blocks.
Q: Should I collect every expansion immediately?
No. Immediate collection creates unnecessary backtracking. Mark blocked rooms, continue the mission, and return when the matching ability becomes available.
Q: Can I finish cleanup after entering the final escape sequence?
Normal exploration becomes restricted during the ending route, so complete the sector sweep and save before starting the final evacuation sequence.
