After receiving a distress signal from a Space Pirate frigate in orbit, bounty hunter Samus Aran boards the vessel and discovers the Pirates have been conducting biological experiments. When the frigate is destroyed, Samus pursues her nemesis Ridley to the surface of the planet Tallon IV, where she uncovers the remains of the Chozo civilization and the source of a toxic substance called Phazon that is corrupting the planet's ecosystem.
A 3D exploration-focused metroidvania with first-person shooting mechanics and the first 3D entry in the Metroid series, Metroid Prime follows Samus Aran after the events of Metroid (1986) as she boards a Space Pirate frigate, then chases her escaping archrival Ridley into the intricately structured Tallon IV, a planet full of deadly wildlife and former home to the advanced and ancient Chozo race.
