- Metroid Zero Mission missile locations are easiest to track by region, map marker, and required ability.
- Collect early expansions in Brinstar, then revisit blocked rooms after gaining Speed Booster, Super Missiles, and Power Bombs.
- Save ammunition before major bosses, since Missile Tanks increase capacity rather than restoring missiles immediately.
- Use a final cleanup route through Brinstar, Norfair, Kraid, Ridley, and Chozodia after the main story.
Metroid Zero Mission Missile Locations by Region
Metroid Zero Mission missile locations are distributed across the entire Zebes map, with many expansions placed behind movement, weapon, or Morph Ball checks. The most efficient approach is not to search every room immediately. Instead, collect the missiles available during normal progression, mark blocked rooms, and return after acquiring the ability that matches the obstacle.
The regional route below organizes missile hunting around practical landmarks rather than unsupported room numbering. Use the in-game map to match each clue to its room, then check the surrounding walls, floors, ceilings, and side passages for hidden blocks.
| Region | Best search areas | Common requirements | Recommended timing |
|---|---|---|---|
| Crateria | Opening ruins, elevated ledges, concealed Chozo passages | Basic movement, Morph Ball | Early route and first cleanup |
| Brinstar | Morph Ball tunnels, bombable floors, vertical shafts, side rooms | Morph Ball, Bombs, Missiles | Early route, then revisit |
| Kraid's Lair | Side rooms, narrow tunnels, missile-door branches | Bombs, Missiles, later movement | Before or after Kraid |
| Norfair | Heated side rooms, long corridors, vertical chambers | Varia Suit, Speed Booster, Hi-Jump Boots | Main route and mid-game cleanup |
| Ridley's Lair | High ledges, hidden shafts, bombable floors | Speed Booster, advanced movement, Power Bombs | Late game |
| Chozodia | Chozo ruins, crashed ship, Power Bomb areas | Power Bombs, late movement upgrades | Post-game cleanup |
When a Missile Tank is visible but unreachable, mark the room and continue the main route. Returning with the correct ability is usually faster than forcing an early detour.
Brinstar
Search Morph Ball tunnels, suspicious floors, and early Chozo side rooms. Bombs reveal several useful branches.
Norfair
Check heated rooms after obtaining the Varia Suit. Speed Booster corridors often connect missile expansions with larger routes.
Ridley's Lair
Inspect vertical shafts and concealed side rooms. Several pickups become practical only after advanced movement upgrades.
Chozodia
Treat the post-game area as a major cleanup zone. Power Bombs and late-game abilities reveal additional missile paths.
Step-by-Step Missile Collection Route
Collect the Early Brinstar Expansions
Begin with Brinstar because the region introduces the core tools used for missile hunting. Obtain the Morph Ball and Bombs, then revisit nearby tunnels and suspicious dead ends. Check platforms above the main route and floors that appear wider than normal.
Red doors are important route signals. If a side room contains a red door but you do not yet have Missiles, remember its location and return after the first Missile upgrade. Once Missiles are available, use them to open progression branches and optional rooms.
Clear Kraid's Lair Before Leaving the Area
Search Kraid's Lair while the region is already part of the main route. Check side rooms before entering the boss chamber, especially narrow passages connected to Morph Ball routes or missile doors.
Do not treat the boss path as the only useful route. The surrounding rooms often contain expansions that are easier to collect before later regions introduce more complicated movement checks.
Use Norfair for Mid-Game Cleanup
Return to Norfair after obtaining the Varia Suit and the movement upgrades that make heated rooms safer. Search long horizontal corridors for Speed Booster opportunities, then inspect high ledges and vertical chambers after gaining Hi-Jump Boots.
Norfair is a good place to increase maximum ammunition before Ridley's Lair. Refill at available recovery rooms and avoid spending missiles unnecessarily on ordinary enemies when a locked route or boss encounter is nearby.
Finish Ridley and Chozodia Cleanup
Late-game Missile Tanks commonly require abilities such as Speed Booster, Shinespark movement, Power Bombs, Screw Attack, or Gravity Suit access. Once the main story opens the post-game route, search Chozodia thoroughly before returning to earlier regions.
Use the map to identify unexplored squares and item markers. A final sweep through Brinstar, Norfair, Kraid's Lair, Ridley's Lair, and Chozodia is more reliable than relying on memory alone.
| Collection phase | Main objective | Abilities to prioritize | What to inspect |
|---|---|---|---|
| Early game | Build basic missile capacity | Morph Ball, Bombs, Missiles | Red doors, tunnels, bombable floors |
| Mid game | Expand capacity before deeper areas | Varia Suit, Hi-Jump Boots, Speed Booster | Heated rooms, high ledges, long corridors |
| Late game | Open advanced expansion routes | Super Missiles, Power Bombs, Screw Attack | Green doors, special blocks, hidden shafts |
| Post-game | Finish the regional sweep | Gravity Suit, Power Grip, advanced movement | Chozodia, missed map squares, late-game barriers |
Missile Tanks raise the number of missiles Samus can carry; they do not automatically refill ammunition. Visit a recharge room before a boss or long exploration sequence.
Requirements and Hidden Route Clues
Missile expansions are designed to teach the relationship between equipment and exploration. A blocked pickup is not necessarily part of the current route. The requirement table below helps determine whether to search now or return later.
| Obstacle or clue | Likely requirement | Search method |
|---|---|---|
| Small horizontal tunnel | Morph Ball | Check both entrances and bomb suspicious blocks |
| Cracked floor or wall | Bombs or Power Bombs | Test nearby surfaces in Morph Ball form |
| Red door | Missiles | Return after collecting the first Missile upgrade |
| Green door | Super Missiles | Revisit after the stronger missile upgrade |
| Yellow door or special block | Power Bombs | Clear the surrounding room and inspect newly opened space |
| High ledge | Hi-Jump Boots, Space Jump, or Power Grip | Check platforms above the normal route |
| Long empty corridor | Speed Booster or Shinespark | Look for a straight running line and nearby breakable blocks |
| Enemy blocking a vertical route | Ice Beam or improved movement | Freeze targets or return after gaining a traversal upgrade |
| Hidden wall passage | Bombs, Power Bombs, or Wave Beam | Test walls near dead ends, item platforms, and map gaps |
Bomb Check
Bomb floors near dead ends, item platforms, and narrow ledges. A plain-looking route may conceal a drop or side tunnel.
Speed Booster Check
Look for long, uninterrupted corridors. If the path ends near a suspicious wall, return with a charged run or Shinespark setup.
Power Bomb Check
Use Power Bombs in rooms with unusual open space, yellow doors, or clusters of special blocks. Search the entire cleared area afterward.
A useful rule is to inspect the room’s shape before attacking every surface. Missile expansions often sit at the end of a short puzzle: a bombable floor, a narrow Morph Ball tunnel, a platforming climb, or a running corridor. If the room contains a clear visual hint but the current equipment cannot solve it, leave a map reminder and continue.
Search the immediate room first, then the two or three connected rooms that form the same puzzle. This keeps exploration focused without turning every map revisit into a full-region restart.
Missile Capacity and Combat Preparation
Missile Tanks support both exploration and combat. Their most visible function is increasing ammunition capacity, but the extra capacity also makes boss preparation more forgiving. The best pickups to prioritize are those located near the main route or accessible with abilities you already own.
| Upgrade type | Main value | Collection priority | Typical use |
|---|---|---|---|
| Missile Tank | Raises standard Missile capacity | High during story progression | Red doors, armored enemies, bosses |
| Super Missile Tank | Raises Super Missile capacity | High after Super Missiles | Green doors and heavy damage |
| Power Bomb Tank | Raises Power Bomb capacity | Medium during cleanup | Special blocks and large-area clearing |
| Energy Tank | Raises maximum Energy | High before dangerous regions | Bosses, heat, long exploration routes |
| Reserve Tank | Adds emergency Energy storage | Cleanup priority | Recovery during difficult encounters |
Before entering a major fight, use this preparation sequence:
- Save the game.
- Refill Energy and missiles.
- Equip the weapon needed for the encounter.
- Check whether nearby side rooms contain an uncollected expansion.
- Avoid spending the full missile supply on ordinary enemies immediately before the boss door.
Kraid and Mother Brain both reward careful ammunition management, while Ridley and Mecha Ridley place greater emphasis on movement and safe damage windows. Extra Missile capacity is helpful, but it does not replace learning attack patterns. If a boss attempt fails, review positioning first and ammunition use second.
Missile Collection Checklist:
- Collect the early Brinstar expansions after obtaining Morph Ball and Bombs
- Open every practical red-door branch before leaving Kraid's Lair
- Revisit Norfair with Varia Suit, Hi-Jump Boots, and Speed Booster
- Check Ridley's Lair for high ledges, hidden shafts, and Power Bomb routes
- Complete the Chozodia sweep before the final global map cleanup
Use unexplored map squares and visible item markers together. A cleared room can still contain a missed expansion if the map shows an unresolved branch or a blocked route nearby.
Final 100% Missile Sweep and FAQ
The final sweep should happen after the main story route and the major post-game upgrades are available. Start in Chozodia, then move through the earlier regions in a consistent order. This avoids repeatedly crossing the same map connections and makes missed markers easier to identify.
| Final sweep order | Region | Main checks |
|---|---|---|
| 1 | Chozodia | Power Bomb blocks, crashed ship routes, late movement passages |
| 2 | Ridley's Lair | High ledges, Speed Booster corridors, concealed shafts |
| 3 | Norfair | Heated side rooms, green doors, vertical chambers |
| 4 | Kraid's Lair | Morph Ball tunnels, missile doors, hidden floors |
| 5 | Brinstar | Early branches, bomb blocks, map gaps near Chozo rooms |
| 6 | Crateria | Opening-area ledges and previously inaccessible passages |

Q: Where should I start looking for Metroid Zero Mission missile locations?
Start in Brinstar after obtaining Morph Ball and Bombs. Search nearby tunnels, bombable floors, red-door branches, and side rooms before moving deeper into Zebes.
Q: Why can I see a Missile Tank but not reach it?
The room probably requires a later ability such as Speed Booster, Hi-Jump Boots, Super Missiles, Power Bombs, Screw Attack, or Gravity Suit. Mark the room and return during cleanup.
Q: Do Missile Tanks refill my ammunition?
No. Missile Tanks increase maximum capacity. Use recharge rooms or enemy drops to restore missiles before bosses and long routes.
Q: What is the best order for collecting missed missile expansions?
Finish the main story, clear Chozodia, then sweep Ridley's Lair, Norfair, Kraid's Lair, Brinstar, and Crateria using map markers and ability checks.
If the completion percentage is lower than expected, revisit regions with unexplored map squares first. Unfinished map branches are often a faster clue than searching every completed room manually.
