Missile Tank
Missile Tanks are collectible items that increase Samus's maximum missile capacity by 5. Missiles are secondary weapons used to open red doors and deal significant damage to bosses and tougher enemies. There are 25 Missile Tanks in total, allowing for a maximum of 255 missiles. Collecting them all is highly recommended for late-game challenges.
Energy Tank
Energy Tanks are collectible items that increase Samus's maximum energy by 100 units (one full bar). There are 8 Energy Tanks in total, significantly boosting Samus's survivability. These are crucial for enduring long stretches without save points and for surviving boss encounters. Always prioritize finding these when exploring.
Bombs
Bombs are an ability acquired with the Morph Ball. While in Morph Ball form, Samus can deploy small bombs that explode after a short delay. These are primarily used to destroy certain blocks, reveal hidden passages, and damage enemies. They are essential for uncovering many secrets and progressing through the environment.
