Metroid Prime is a first-person action-adventure video game developed by Retro Studios and released by Nintendo in 2002. It is the first game in the Metroid Prime series and a reimagining of the popular Metroid franchise.

In the game, the player assumes the role of bounty hunter Samus Aran, who is sent to investigate a research station orbiting the planet Tallon IV. The station has gone dark, and the only clues to what has happened are scattered messages and recordings left behind by the former inhabitants.

As Samus explores the station and the planet below, she discovers that a powerful entity known as the Phazon is being used by a group of space pirates to create powerful weapons. Samus must stop the pirates and uncover the secrets of the Phazon, while also battling dangerous creatures and exploring the alien landscapes of Tallon IV.

The game features a mixture of first-person shooting and exploration elements, with a heavy emphasis on puzzles and discovery. The player can use various upgrades and weapons to navigate the environment and defeat enemies, and must often backtrack to previously explored areas to find new items and paths.

Metroid Prime was widely praised upon its release for its immersive atmosphere, engaging gameplay, and inventive use of the first-person perspective. It has since become a classic of the video game medium and a beloved entry in the Metroid series.
