- Metroid Fusion all endings are tied to clear performance rather than separate story branches.
- Item percentage and clear time are the two main goals to track before the final escape.
- Standard clears require defeating the final boss and completing the evacuation sequence.
- Higher completion comes from collecting Energy Tanks, Missile Tanks, Super Missile Tanks, and Power Bomb Tanks.
- Link features with Metroid: Zero Mission are separate from Fusion’s normal ending conditions.
Metroid Fusion All Endings Explained
Metroid Fusion does not use branching dialogue choices or selectable story routes. Instead, the ending presentation reflects how you complete the adventure, especially your item completion percentage and clear time. The main story remains the same: Samus investigates the B.S.L. station, confronts the X Parasite outbreak, defeats the SA-X, and escapes before the station collides with SR388.
The practical goal is to finish the story first, then replay for a faster time or higher collection percentage. A normal clear is enough to see the conclusion, while stronger results provide additional ending presentation and completion targets.
| Completion Goal | Main Requirement | What It Measures | Best For |
|---|---|---|---|
| Standard Story Clear | Defeat the final boss and escape | Story completion | First playthrough |
| Fast Clear | Finish with an improved time | Route efficiency and movement | Speed-focused runs |
| High-Completion Clear | Collect more expansions before finishing | Exploration and cleanup | Collectors |
| 100% Item Clear | Collect every counted expansion | Maximum item percentage | Completionists |
| Fast High-Completion Clear | Combine strong time and item collection | Advanced routing | Experienced players |
Treat the endings as performance results, not separate campaigns. Finish the story once, then use your completed knowledge of the B.S.L. layout to improve time or item percentage on later runs.

Ending Goals and Performance Conditions
The most reliable way to pursue a stronger ending is to separate your goals. A fast run and a 100% run use different priorities, so trying to maximize both during a first playthrough can create unnecessary pressure.
For a standard clear, focus on the critical route and the abilities required to open each story gate. For a high-completion clear, collect visible expansions when convenient, mark blocked rooms, and return after acquiring Space Jump, Gravity Suit, Screw Attack, Power Bombs, and the later beam upgrades.
| Run Type | Priority | Recommended Approach | Common Risk |
|---|---|---|---|
| First Clear | Story progression | Follow Navigation Room objectives | Missing optional rooms |
| Fast Clear | Time | Avoid unnecessary item detours | Taking damage from rushed movement |
| Collection Run | Item percentage | Revisit each Sector methodically | Forgetting ability-gated rooms |
| 100% Run | Every counted expansion | Use a sector checklist | Starting final escape too early |
| Challenge Run | Time plus collection | Plan route before playing | Losing time to difficult Shinespark setups |
The game’s ending system rewards the final result recorded on the completed save. Because the final evacuation sequence limits normal exploration, finish optional cleanup before committing to the last story route.
Before entering the last sequence, check your map, ammunition capacity, Energy Tanks, and expansion count. Once the evacuation begins, normal item cleanup is no longer the priority.
Finish the Main Story
Complete the intended route through the Main Deck and Sectors, acquire the necessary beam and movement upgrades, defeat the final threats, and escape the B.S.L. station.
Review Your Result
Check your clear time and item percentage after the ending. Use these values to decide whether your next run should focus on speed, exploration, or both.
Mark Missed Rooms
Compare your map with unexplored rooms, suspicious dead ends, Speed Booster corridors, Morph Ball tunnels, and locations blocked by abilities you did not yet possess.
Perform Sector Cleanup
Return to earlier Sectors after obtaining late-game abilities. Collect expansions in a planned order instead of moving randomly between elevators.
Replay for a Stronger Clear
Start a new run using your improved route knowledge. Skip optional detours for a fast clear, or reserve a late-game cleanup phase for a high-completion attempt.
How to Prepare for a High-Completion Ending
A high-completion run depends on recognizing ability gates. Many rooms cannot be cleared during the first visit because Samus lacks the correct weapon, suit, or movement ability. This is normal progression rather than a sign that the map is incomplete.
The strongest cleanup point is late in the story, when Samus has access to most major movement tools. Space Jump improves vertical exploration, Gravity Suit removes underwater movement penalties, Screw Attack clears specific obstacles, and Power Bombs reveal hidden blocks and passages.
| Item Category | Typical Locations | Useful Requirements | Cleanup Advice |
|---|---|---|---|
| Missile Tanks | Side rooms, missile blocks, tunnels | Missiles, Bombs, Speed Booster | Check every Sector map |
| Super Missile Tanks | Hidden branches and weapon-gated rooms | Super Missiles, later movement tools | Revisit green-door routes |
| Power Bomb Tanks | Hidden blocks and advanced puzzles | Power Bombs, Space Jump | Sweep after Power Bomb access |
| Energy Tanks | Vertical rooms and difficult platforms | Hi-Jump, Space Jump, Gravity Suit | Prioritize survival upgrades |
| Story Upgrades | Data Rooms and boss routes | Mission progression | Do not confuse with optional items |
Before the Final Escape:
- Review every Sector map for unexplored rooms
- Collect visible Missile, Super Missile, Power Bomb, and Energy expansions
- Revisit blocked routes after gaining Space Jump or Gravity Suit
- Recharge health and ammunition before the final boss sequence
- Confirm that optional cleanup is finished before evacuating
Collect obvious expansions during the story, mark difficult rooms mentally, then complete a full map sweep before entering the Restricted Zone and final evacuation route.
Fast Clear Tips for Better Ending Results
A faster clear is built around movement consistency rather than risky damage trades. Learn the elevator network, remember which Data Rooms are mandatory, and avoid returning to a Sector unless a new ability opens a worthwhile route.
The Speed Booster is especially important because it shortens long corridors and enables Shinespark movement. Practice storing a Shinespark, releasing it in the correct direction, and using it to cross vertical or horizontal gaps. These techniques can improve both speed runs and collection routes.
| Technique | Use | Practice Focus | Benefit |
|---|---|---|---|
| Speed Booster | Cross long corridors quickly | Maintain a clear running line | Reduces travel time |
| Shinespark | Reach distant platforms or blocks | Store and release momentum | Opens shortcuts and expansions |
| Bomb Jump | Gain height in Morph Ball form | Place bombs in a steady rhythm | Reaches narrow vertical routes |
| Wall Jump | Adjust vertical movement | Change direction at wall contact | Helps with advanced traversal |
| Pattern Recognition | Improve boss fights | Learn attack openings | Saves health and ammunition |
Use safe boss strategies during early attempts. A missed attack is usually less costly than taking repeated contact damage and needing to reload or revisit a Recharge Room. Once patterns are familiar, optimize positioning and ammunition use.
Do not force a 100% route and a fast route to serve the same purpose. A speed-focused run should minimize detours, while a completion run should accept extra travel for hidden rooms and ability-gated expansions.
Route Memory
Remember elevator locations, Data Rooms, Navigation Rooms, and required returns to the Main Deck.
Boss Control
Learn safe openings before attempting faster damage strategies.
Resource Use
Save missiles for armored targets and use beams against ordinary enemies when practical.
Map Reading
Inspect floors, ceilings, isolated platforms, and colored doors when a route appears blocked.
Unlockables, Link Features, and FAQ
The original Game Boy Advance versions also included a historical link feature involving Metroid: Zero Mission. This feature should not be counted as a separate Metroid Fusion ending. It is distinct from the normal completion system based on story progress, item percentage, and clear time.
The official Nintendo materials also place Metroid Fusion among the Game Boy Advance titles available through supported Nintendo Switch Online services. That modern availability does not create new ending conditions; the game’s completion goals remain based on the original adventure.
| Feature | Part of Fusion’s Ending System? | Explanation |
|---|---|---|
| Story completion | Yes | Required to finish the game |
| Clear time | Yes | Used to evaluate speed-focused results |
| Item percentage | Yes | Used to evaluate exploration and completion |
| Link with Zero Mission | No | Separate historical hardware feature |
| Nintendo Switch Online availability | No | Modern access option, not an ending condition |
| External cheat devices | No | Not part of the normal game software |
Q: How many endings does Metroid Fusion have?
Metroid Fusion has one main story conclusion with different ending presentations tied to completion performance. The meaningful variables are clear time and item percentage, rather than branching story choices.
Q: What is needed for the best Metroid Fusion ending?
Aim for the highest available item completion while also improving your clear time. Collect every counted expansion, finish optional cleanup before the final evacuation, and complete the story successfully.
Q: Can I collect missed items after finishing the game?
You can use your experience from the completed run to begin another playthrough, but the final escape sequence is not designed for normal post-ending exploration. Perform your cleanup before starting the last route.
Q: Is the Zero Mission link feature another ending?
No. The original Game Boy Advance link functionality is a separate cross-game feature. It should not be confused with the completion-based ending presentations in Metroid Fusion.
For a first playthrough, prioritize the story and learn the station layout. On the next run, choose one clear objective—speed or completion—then combine both after your route becomes familiar.
