Metroid Prime 3 has so far been released in two formats, both on the Nintendo Wii. The original stand-alone version arrived in 2007, while the Metroid Prime Trilogy compilation arrived in 2009. The changes discussed below are made in relation to the original stand-alone Wii NTSC version.
Note: All the changes in the original PAL version above were used in the Metroid Prime Trilogy version unless otherwise stated.
Many thanks to the following people who submitted information about differences found in various versions of the game.
