Universal Ammunition Expansions, also known simply as UA Expansions, are found throughout Metroid Prime: Hunters. When collected, they increase Samus Aran's Universal Ammunition capacity by 30 units and fully restore her current supply. There are 12 different expansions, granting a total of 400 units once all are acquired. They serve the same purpose as the Beam Ammo Expansions in Metroid Prime 2: Echoes.
