Abilities and capacity

Maru Mari / Morph Ball
This upgrade lets Samus curl into ball form and travel through low passages. Remember the tunnels you previously could not enter and map their destinations afterward.

Bombs
Place Bombs with B in ball form to attack or test suitable blocks. Leave room to recover and connect any revealed passage to your existing map.

Energy Tank
An Energy Tank expands Samus’s energy capacity. Build a useful reserve before difficult exploration, and distinguish the larger maximum from the amount of energy currently available.

Missile Rocket
A Missile Rocket pickup increases the missile supply. Switch weapons with Select when missiles are needed, and replenish ammunition before entering a long boss route.
Every Metroid power item
Power items wait on Chozo statues in the original 1986 NES game.

Quick notes
- Use small passages as remembered clues. The Morph Ball is the Maru Mari in the original English manual.
- Test blocks carefully after finding Bombs. Bombs are placed with B while Samus is in ball form.
- Distinguish capacity from current reserves. An Energy Tank expands the amount of energy Samus can hold, and a Missile Rocket pickup expands the missile supply.
Write the upgrade beside the blocked route it solves; that turns a pickup into a concrete next step.
