All missile expansion locations in Metroid Prime 4: Beyond
Finding all of Metroid Prime 4: Beyond‘s missile expansions is a task that spans the entire game. You can get some early on, but most require upgrades like the Spider Ball or Grapple Hook that remain out of reach until late in the game. Expect to backtrack quite a lot if you want to finish up with all 48 missile expansions, which is a good idea. Missiles deal heavier damage than even the upgraded power beam, and once you unlock super missiles, each of those consumes five regular missiles.
