The game uses a side-scrolling perspective across a connected world rather than isolated stages. Samus runs, jumps, shoots, and uses the Morph Ball to enter narrow passages, while upgrades such as missiles, Energy Tanks, Ice Beam, and Space Jump expand combat and movement options. Progress is tied to hunting Metroids in each zone; defeating enough lowers the planet's lava, opening deeper areas. Success depends on map memory, hidden blocks, movement tools, and boss-style encounters with evolving Metroids.

Samus Aran

A legendary bounty hunter hired by the Galactic Federation to exterminate the Metroids on SR388.

Baby Metroid

A newly hatched Metroid encountered near the ending, crucial to the story's emotional payoff and later series events.

Search thoroughly for missile expansions and Energy Tanks early, since they make later fights much safer. Against the different Metroid evolutions, stay mobile, watch their attack height, and use missiles for efficient damage. If a path seems blocked, look for breakable blocks and hidden passages, especially in Morph Ball-sized spaces. After lava recedes, revisit earlier rooms to collect missed upgrades with less risk.

Tips and tricks

Missiles are far more effective than the basic beam against Metroids.

Tips and tricks

Refill health and missiles before entering a new zone whenever possible.

Tips and tricks

Many upgrades are hidden behind breakable blocks in seemingly plain walls or floors.

User Reviews

A remarkably moody adventure for the Game Boy, with strong atmosphere despite the monochrome visuals.

User Reviews

Exploration is rewarding, though the lack of an in-game map makes backtracking more demanding.
