Metroid (NES / Famicom) Walkthrough, Secrets & Cheat Codes
Metroid is a maze you unlock with power-ups, not a level list. The breakthrough is the hidden Brinstar tunnel revealed by shooting a specific seemingly-solid wall — it connects two regions and slashes your travel time. Reach the Ice Beam and Wave Beam, then push to Mother Brain.
1Game Basics
A side-scrolling exploration shooter: bounty hunter Samus Aran raids planet Zebes to stop the Metroids.
2Core Gameplay
You start weak and gain abilities — Maru Mari (morph ball), bombs, long beam, ice/wave/plasma beams, and missiles — that open new paths. Backtracking is the core loop; every item gate is a door you'll return to.
3Step-by-Step Walkthrough
- In Brinstar, shoot the wall at the dead-end just above the first 'wave beam' hint to reveal a hidden passage linking to Norfair.
- Collect the Ice Beam (freezes enemies) and Wave Beam (passes through walls) to access frozen and shielded areas.
- Use bombs in ball form to break hidden blocks blocking shafts.
- Reach Tourian and defeat Mother Brain with missiles + beams.
4Hidden Secrets & Easter Eggs
Finish the game quickly (under certain time limits) to see Samus remove her helmet and reveal she is a woman — a 1986 shocker. The hidden Brinstar tunnel is the most-used sequence-break in speedruns.
5Cheats & Codes
Metroid uses password continues rather than codes; the real 'cheat' is knowing item order. Emulator save states let you practice the tough ball-sections.
6Player Reviews & Tips
Fans love the isolation and the 'ability-gated map' design that defined a whole genre (Metroidvania). The hidden passage is the tip every newcomer wishes they'd known.
