The Story
Samus's adventure on the Nintendo GameCube takes place in the past. After the events of the first Metroid adventure, but before Metroid II, Samus learns that there were Space Pirate vessels in orbit as she fought on the surface of Zebes. She traces one of these to an orbit around a planet called Tallon IV and discovers an enormous Space Pirate research operation in progress. The Space Pirates are experimenting with a dangerous mutagen called Phazon, combining it with local life forms as they try to rebuild their army. Samus must delve deep into magma-filled caverns, poisonous mines, and icy caves as she tries to stop the Space Pirates' sinister plan.
