Super Missile Ammo

Super Missile Ammo is an item in the Metroid series that replenishes Samus' Super Missile reserves. They only appear in Super Metroid and Metroid: Zero Mission as those are the only two games where Super Missiles have their own stock of ammunition. Super Missile Ammo looks like a Super Missile floating in midair and requires Samus to touch it in order for her to collect it. Super Missile Ammo is dropped by defeated enemies in the aforementioned games, but it's less common that regular Missile Ammo.

Each unit of Super Missile Ammo restores two Super Missiles when collected.
