Metroid Zero Mission Complete Walkthrough

This walkthrough follows the intended progression of Metroid: Zero Mission while highlighting the abilities, upgrades, and shortcuts that unlock each next route. Use the area checkpoints to recover when you are lost, identify the next objective, or decide which previously inaccessible rooms are now worth revisiting.

1

Crateria and the Opening Ruins

Reach Brinstar and begin the first Chozo-guided route. Explore the opening ruins, follow the Chozo Statues toward the planet's interior, clear basic enemies with your starting beam, and descend into Brinstar.

2

Brinstar: Early Exploration

Collect the Morph Ball, Bombs, Long Beam, and early Missile expansions. Roll into small tunnels, bomb suspicious walls to reveal hidden routes, and follow the main Chozo Statue route toward the first major boss area.

3

Brinstar: Deorum and the Kraid Route

Use Missiles to open red doors, defeat Deorum to clear the path into the lower region, and continue toward Kraid's lair with the upgrades needed to survive the deeper rooms.

4

Kraid's Lair

Fight through the lair's platforming route and defeat Kraid by firing Missiles into his open mouth when he exposes his weak point, opening the route into Norfair.

5

Norfair: Heat and Mobility Upgrades

Acquire the Varia Suit, Speed Booster, and Hi-Jump Boots, then learn to preserve a running boost through long corridors as new abilities open routes toward Ridley's area.

6

Ridley's Lair

Cross the dangerous lower area with heat protection and movement upgrades, search side rooms for Energy and Missile Tanks, and defeat Ridley to reach Tourian.

7

Tourian

Clear the Metroid gauntlet by freezing Metroids with the Ice Beam and destroying them with Missiles, then continue through the containment areas to the Mother Brain chamber.

8

Mother Brain and the Escape

Break the protective barrier and fire Missiles at the exposed eye while avoiding Rinkas and the beam attack, then follow the timed escape route without stopping for optional items.

9

Zero Suit Samus and the Space Pirate Mothership

Survive without the Power Suit by using stealth, line-of-sight, and environmental cover to avoid Space Pirate patrols, then move through the Mothership to recover Samus's equipment.

10

Chozodia and Mecha Ridley

Use the Power Grip and recovered abilities to explore the Chozo ruins, reach the Mothership's central route to defeat Mecha Ridley, and finish remaining exploration for optional items.

Quick Tips

  • Bomb suspicious floors and walls, especially around dead ends and item platforms.
  • Blue doors open with the standard beam, while red doors require Missiles.
  • Use map stations and save rooms whenever they become available.
  • Freeze Metroids before attempting to pass narrow corridors in Tourian.
  • The Zero Suit section rewards patience: observe patrol patterns before moving.
  • Chozodia connects back to earlier regions, so revisit old map gaps after gaining new abilities.

Metroid Zero Mission Beginner Guide

Metroid: Zero Mission is built around exploration and backtracking. If a room appears impossible, the solution is usually a new ability, a different entrance, a hidden block, or a door that requires a specific weapon. These fundamentals explain how to read the world and recognize the next step.

How Exploration Progression Works

Explore until a route is blocked, then search for an upgrade or alternate path. Chozo Statues, map stations, and the shape of connected rooms usually point toward the intended route.

Saving, Energy, and Missile Refills

Save Rooms permanently record progress, and Recharge Rooms restore Energy and Missiles. A good preparation routine is save, refill, then enter the next unexplored route.

Understanding Door Colors

Blue doors open with the standard beam, red doors require Missiles, green doors need Super Missiles, and yellow doors require Power Bombs.

Reading Chozo Statues

Statues mark the intended route, reveal the general direction of the next objective, and often indicate a nearby ability or equipment pickup.

Core Movement Techniques

Morph Ball tunnels, wall jumping, and the Speed Booster's Shinespark open routes that standing play cannot reach. Practice in safe rooms first.

Using Beams and Missiles

The Long Beam extends range, the Charge Beam boosts damage while conserving ammunition, and Missiles open red doors while hitting bosses hard.

When to Revisit Earlier Areas

New abilities such as Bombs, Speed Booster, and Power Grip frequently open multiple older routes at once, exposing optional Missile and Energy Tanks.

Basic Combat and Survival

Shoot from a safe distance, collect enemy drops before long sequences, and spend the first attempts learning a boss's attack cycle before forcing damage.

Check the map for unexplored rooms near the last major upgradeSave, refill, then push into the next routeMark locked doors and return once you hold the right weaponPrioritize the main route when lost, then backtrack for cleanup

Metroid Zero Mission Map and Item Locations

This regional item index groups major equipment and expansion pickups by area. If an item is currently inaccessible, continue the main route until the listed weapon, movement upgrade, or environmental protection becomes available.

Morph Ball

Found on the early Chozo-guided route and used to enter narrow tunnels across all of Zebes.

Metroid Zero Mission Boss Guide

Each boss encounter rewards a different approach. Start with the preparation tip for a spoiler-free idea of the fight, then use the plan for attack patterns, safe positions, and damage windows.

Deorum

Early Boss

Brinstar. Stay mobile around the arena and strike when the creature exposes its vulnerable eye. Wait for the opening, fire Missiles into the eye, and reposition after every attack.

Kraid

Major Boss

Kraid's Lair. Watch the boss's face and use the platforms to stay aligned with his weak point. Fire Missiles into his open mouth, destroy incoming projectiles, and keep moving vertically.

Ridley

Major Boss

Ridley's Lair. Learn the rhythm of Ridley's movement before committing to an attack. Fire Missiles during exposed windows, avoid trading contact damage, and prioritize survival in crowded phases.

Mother Brain

Final Boss

Tourian. Break the protective barrier, then fire Missiles at the exposed eye between Rinka waves and beam attacks, keeping room to jump or crouch after each exchange.

Mecha Ridley

Post-Game Boss

Space Pirate Mothership. Treat the fight as a test of positioning and timing: avoid the large mechanical attacks, then punish the exposed target with Missiles and Super Missiles.

Boss Tips

  • Save and refill Missiles before entering any boss route.
  • Spend the first attempt learning the attack pattern instead of forcing damage.
  • Keep a Missile reserve for the final phase of each fight.
  • Reposition after every attack instead of standing in one spot.

Metroid Zero Mission Weapons and Power-Ups

Samus gradually expands her movement, defense, and firepower across Zebes. Many upgrades are both combat tools and exploration keys, so the most efficient route combines the main path with later backtracking through previously inaccessible passages.

Morph Ball

Roll through narrow tunnels and enter passages unreachable in standing form; it also enables Bombs and Power Bombs.

Long Beam

Extends arm cannon range, letting you hit distant switches and clear enemies across long rooms.

Missiles

Powerful ammunition that destroys armored enemies and opens red missile doors; several bosses require them.

Bombs

Drop explosives in Morph Ball form to break bombable blocks, reveal hidden passages, and set up Bomb Jumps.

Varia Suit

Reduces incoming damage and protects against high-temperature rooms, making Norfair travel survivable.

Charge Beam

Charges a stronger shot that conserves ammunition and makes standard enemies easier to defeat.

Speed Booster

Accelerate into a high-speed dash that breaks Speed Booster blocks and enables long-distance Shinespark routes.

Hi-Jump Boots

Increases jump height to reach higher ledges, platforms, and shafts beyond the standard jump.

Ice Beam

Freezes enemies into temporary platforms and is the key tool for handling Metroids in Tourian.

Wave Beam

Shots pass through certain walls and follow a wider path, reaching targets hidden behind barriers.

Gravity Suit

Further reduces damage and removes movement penalties in liquid environments, opening underwater routes.

Super Missiles

Stronger missiles that open green missile doors and deal high damage to bosses and armored enemies.

Screw Attack

Damages enemies on contact during a spin jump and breaks Screw Attack blocks across late-game routes.

Power Bombs

Creates a large-area explosion that destroys special blocks, reveals hidden passages, and clears enemy groups.

Power Grip

Grab and pull up from ledges, opening ledge-based routes throughout post-game Chozodia.

Convert a Speed Booster run into a Shinespark

Freeze enemies to build improvised platforms

Open red, green, and yellow doors with the right ammunition

Combine suits and beams to unlock every region

Metroid Zero Mission 100 Percent Completion Guide

A complete file requires more than finishing the main story. Use the regional checklist to record Missile, Super Missile, Power Bomb, Energy Tank, and Reserve Tank pickups, then revisit earlier areas once the abilities for blocked passages become available.

Brinstar

Early-Game Region

Collect Missile, Energy, and Reserve Tanks hidden in Morph Ball tunnels, bombable floors, and hidden wall passages. Major upgrades here include Morph Ball, Long Beam, Bombs, Charge Beam, and Varia Suit.

Norfair

Heat Region

Use the Varia Suit for safe access to heated rooms. Missile and Super Missile Tanks sit behind green doors and Speed Booster or Power Bomb passages.

Kraid's Lair

Boss Region

Inspect side rooms and Morph Ball passages for Missile Tanks, then return with Super Missiles and Power Bombs to finish the region.

Ridley's Lair

Late-Game Region

Search vertical shafts and side rooms after obtaining the movement upgrades needed to cross them; Power Bombs reveal large hidden sections.

Tourian

Final Story Region

Focus on the final objective and the Metroid encounters. Preserve Ice Beam and Missile resources, then use the post-game map to clean up earlier regions.

Chozodia

Post-Game Region

Explore the crashed spacecraft and surrounding ruins once the story opens the area. Gravity Suit, Screw Attack, and Power Grip support the final sweep.

Final 100% Sweep

Global Checklist

Revisit every region to confirm Missile, Super Missile, Power Bomb, Energy, and Reserve Tank pickups, then use unexplored map squares to find missed rooms.

Metroid Zero Mission Codes and Unlockables
