You’re staring at a wall in Brinstar. It looks solid. You’ve bombed every square inch of the floor, but you’re still stuck. That’s the classic experience. Whether you’re a newcomer or someone who played the 1986 original on the NES and just wanted to see what the Game Boy Advance remake changed, this metroid zero mission guide is here to help you navigate the labyrinth of Zebes without losing your mind. Honestly, the game is a masterpiece of "show, don't tell," but sometimes a little telling helps when you've been running in circles for twenty minutes.
The First Rule of Zebes: Bombs Are Your Best Friend
Forget the Long Beam for a second. The real MVP of the early game is the Morph Ball Bomb. Most players rush through the early corridors of Brinstar thinking they just need to find the next boss. Wrong. You need to be suspicious. See a weird tile? Bomb it. See a corner that looks slightly too empty? Bomb it. Zero Mission is famous for hiding its most vital power-ups behind single-tile blocks that don't look different from the rest of the scenery.
If you’re following this metroid zero mission guide to get a 100% completion rate, you have to embrace the tedium of the "bomb jump." It’s a rhythmic tap-tap-tap. It’s annoying until it’s second nature. But once you master the timing, you can reach ledges that the developers probably didn't intend for you to hit until you had the High Jump Boots. That’s the beauty of this game; it rewards sequence breaking. If you can jump higher than you're supposed to, the game usually lets you stay there.
Kraid and Ridley: Don't Panic
Kraid is huge. Like, screen-filling huge. When you first drop into his lair, it’s intimidating. But here’s the secret: he’s a pushover if you stay calm. You just need to shoot his eyes to make him open his mouth, then spam missiles. It’s a cycle. If you find yourself falling into the spikes at the bottom, stop trying to aim. Just focus on getting back onto the platforms.
Ridley is a different beast entirely. He’s fast, he breathes fire, and he’s generally a jerk. The trick with Ridley is actually staying close. If you back off, he has more room to maneuver and pelt you with fireballs. If you stay right in his face and unload every missile you’ve found up to that point, he goes down surprisingly fast. It’s a glass-cannon fight. You’ll take damage, sure, but you’ll deal it faster.
Beyond the Original: The Stealth Mission
Most people who search for a metroid zero mission guide are actually looking for help with the part the original game didn't have: the Chozo Ruins. After you "beat" Mother Brain, the game isn't over. Samus gets shot down, loses her Power Suit, and you’re left with a pathetic little pistol that only stuns enemies.
This is where the game turns into a stealth horror title.
Basically, stop fighting. You can’t kill the Space Pirates in this section. You can only stun them and run. If they see you, the music changes, the lights turn red, and you’re probably going to die unless you know exactly where the next vent is. My advice? Watch the shadows. The Space Pirates have a very specific patrol pattern. If you wait five seconds, they usually turn around, giving you just enough time to wall-jump into a hidden crawlspace.
- Don't bother charging your pistol unless you have a clear shot.
- The blue sensors on the ground? Jump over them. They’re alarms.
- Use the map. The map shows you the general direction of the Power Suit, but it won't show you the secret paths.
- Look for "cracked" glass. Often, the way forward isn't a door, it's breaking through the environment itself.
Collecting the Good Stuff: Energy Tanks and Power Bombs
You’ll find that as you get deeper into Norfair and Ridley’s lair, your health bar feels increasingly flimsy. You need Energy Tanks. There are 12 of them in total. Some are easy—sitting right in the middle of a hallway—but others require the "Shinespark."
The Shinespark is the hardest mechanic to master in any Metroid game. You run until you glow purple, then crouch to "store" the energy. Then, you jump. You’ll fly in a straight line until you hit something. In Zero Mission, some of the most devious puzzles require you to store a Shinespark, run through a door, slide under a gap, and then unleash it to break through a ceiling three rooms away. It’s intense. If you’re struggling with a specific Energy Tank in the upper parts of Brinstar, it’s probably a Shinespark puzzle. Practice the timing on the long flat stretches near the landing site.
The Power Bomb Trap
Once you get the Power Suit back near the end of the game, you feel invincible. You get Power Bombs. These things clear the whole screen. But beware: using them blindly can actually screw you over. Some rooms have "Pit Blocks" that only appear after a Power Bomb blast, sending you falling into a room full of enemies you weren't ready for. Use them strategically to find hidden exits, not just to kill regular enemies.
Breaking the Game: Sequence Breaking for Fun
Zero Mission was designed with speedrunners in mind. Director Yoshio Sakamoto has talked about how they intentionally built "shortcuts" for players who knew what they were doing. For example, you can actually skip the Long Beam entirely if you’re good at wall-jumping. You can even get the Super Missiles much earlier than intended if you use a well-timed bomb jump in Brinstar.

This isn't just for show. Getting items early makes the boss fights a joke. Imagine walking into the Kraid fight with twice the amount of missiles you're supposed to have. It changes the game from a survival challenge into a victory lap. If you're on your second playthrough, try to see how many "required" items you can ignore. It’s a totally different experience.
Final Tactics for Success
To wrap this up, remember that Zebes is a puzzle, not just an action game. If you're stuck, go back. The game frequently gives you a new tool and expects you to remember a door you saw an hour ago.
- Check your map frequently. Any room with a circle in it still has an item you haven't picked up.
- Save often. The save stations are generously placed, usually right before a boss or a difficult platforming section. Use them.
- The Screw Attack is god-tier. Once you get it, you are basically a whirling blade of death. Most flying enemies will die just by you jumping into them.
- Refill at statues. Chozo statues aren't just for lore; many of them will refill your health and ammo if you stand in their hands or shoot the orb they hold.
Next Steps for Completionists
- Map Out Brinstar First: Before heading to Norfair, ensure you have at least 3 Energy Tanks and 20 Missiles. This makes the heat-damage rooms much more manageable.
- Master the Wall Jump: Spend ten minutes in a vertical shaft practicing. You need to press the opposite direction of the wall and the jump button simultaneously. It’s the single most important skill for finding secrets.
- Identify the "No-Go" Zones: If a room is draining your health and you don't have the Varia Suit, stop. You aren't supposed to be there yet. The game is baiting you into a death trap.
- Save the Power Bombs for Chozodia: While they are useful elsewhere, you’ll need a healthy stock for the final escape sequence to clear debris quickly.
