About This Game
Metroid drops you alone on the planet Zebes as Samus Aran, a bounty hunter in a powered suit, with no map and no instructions. Your job is to find the Metroids - the energy-draining organisms the Space Pirates are weaponising - in the caverns beneath the surface.
Its structure is what made it radical: the world is one continuous, interconnected maze of vertical shafts and hidden passages, and progress comes from abilities rather than keys. Morph Ball, Bombs, the Ice Beam, the Varia Suit; each upgrade silently opens several earlier dead ends. The reveal that the armoured hero is a woman was one of the most famous twists of the 8-bit era, and the entire Metroidvania genre traces directly back to this cartridge.
- One continuous open world with no map screen - exploration is the game
- Ability-gated progression: Morph Ball, Bombs, Ice Beam, Varia Suit
- Multiple endings determined by your completion time
- Samus Aran's identity reveal, one of the era's iconic twists

Tips & Strategy
Bomb every floor
The Morph Ball and Bombs hide more secret passages than any other tool. In a shaft that dead-ends, drop a bomb and stand still.
Ice Beam first, then missiles
Frozen enemies become platforms. Freezing a flying enemy at the right height is often the only way to reach a ledge before you have the Space Jump.
Track your timer mentally
Endings change at set completion times. If you want the best ending, plan a route on your second playthrough rather than exploring blindly.
Health and missile tanks stack
Every Energy Tank adds 100 energy. Grabbing them early turns the Ridley and Kraid fights from endurance tests into normal fights.
