Quick Links
There are 49 Missile Expansions and four Power Bomb Expansions in Metroid Prime Remastered, and players that collect them all will reach the end credits having the ability to carry 250 Missiles and eight Power Bombs. While it is certainly possible to complete the game without earning these capabilities, fans that are interested in 100% completion will need to pick up all the ammunition expansions. This guide is here to assist with that endeavor, and players will find the locations of all Metroid Prime Remastered's Missile Expansions and Power Bomb Expansions below.

Players can find this Missile Expansion under the bridge in the tunnel.
Missile Expansion 3 (Overgrown Cavern)
Metroid Prime Remastered players will run into this Missile Expansion as they roll through the Overgrown Cavern, a hallway that is accessed by riding the Tallon Overworld East elevator.
