The Missile Expansion, known as Missile Tank in the 2D games, is a common Suit Expansion in the Metroid series. It increases Samus's maximum Missile capacity by five. The exceptions to this rule are in Metroid Prime Hunters, where Missile they expand maximum Missile count by ten; Metroid: Zero Mission, where in Hard Mode, Missile Expansions only increase Missile count by three; and in Metroid: Other M, where they increase the count by one Missile at a time.
Missile Expansions are often found hidden in secret passages or rooms. Many of Samus's upgrades that are less suited for battle, such as the Speed Booster or Spider Ball, are more often used to retrieve Missile expansions and other Expansions.
