Metroid Prime is a video game developed by Retro Studios and published by Nintendo for the Nintendo GameCube, released in North America on November 19, 2002. It is the first 3D game in the Metroid series, and is classified by Nintendo as a first-person adventure rather than a first-person shooter, due to the large exploration component of the game. In North America, it was also the first Metroid installment to be released since Super Metroid in 1994; in all other markets, it was released after Metroid Fusion.

Metroid Prime is the first of the three part Prime storyline, which takes place between the original Metroid and Metroid II: Return of Samus. Like previous games in the series, Metroid Prime has a science fiction setting, in which players control the bounty hunter Samus Aran. The story follows Samus as she battles the Space Pirates and their biological experiments on the planet Tallon IV.

Despite initial backlash from fans due to the first-person perspective, the game was released to both critical and commercial success, selling more than a million units in North America alone and becoming one of the most acclaimed games of all time.

Gameplay

As in previous Metroid games, Prime takes place in a large, open-ended world with different regions connected by elevators. Each region has an entire set of rooms separated by doors that can be opened with a shot from the correct beam. The gameplay revolves around solving puzzles to uncover secrets, platform jumping, and shooting foes with the help of a 'lock-on' mechanism that allows circle strafing while staying aimed on the enemy. The game is the first in the series to use a first-person view as opposed to side scrolling, except in Morph Ball mode, when Samus's suit transforms into an armored ball and the game uses a third-person camera.

The protagonist, Samus, must travel through the world searching for twelve Chozo Artifacts that will open the path to the Phazon meteor impact crater, while collecting power-ups that enable the player to reach previously inaccessible areas; the Varia Suit, for example, protects Samus' armor against extreme heat, allowing her to enter volcanic regions. Some of the items are obtained after boss and mini-boss fights, encountered in all regions except Magmoor Caverns.

The heads-up display simulates the inside of Samus's helmet, featuring a radar, a map, ammunition for missiles, a health meter, and a health bar for bosses along with the boss name. The display can be altered by exchanging visors, including one using thermal imaging, another with x-ray vision, and a scanner that searches for enemy weaknesses, and interfaces with certain mechanisms such as force fields and elevators, allowing the player to operate them. Prime also introduces a hint system that provides the player with a general idea of where to go.
