Metroid: Samus Returns is an action-adventure game developed by Nintendo EPD and MercurySteam, and published by Nintendo for the Nintendo 3DS in 2017. A part of the Metroid series, the game is a reimagining of the 1991 Game Boy game Metroid II: Return of Samus. Players control Samus Aran, who is sent by the Galactic Federation to exterminate the parasitic Metroids on their home planet.
The story and structure are similar to the original Metroid II, but the game features improved controls, enhanced visuals and introduces gameplay features and abilities new to 2D Metroid games, such as a melee counterattack and the ability to fire freely at any angle. Development began in 2015, produced by longtime Metroid developer Yoshio Sakamoto. The game received positive reviews for its visuals and improved gameplay over the original game, with many viewing it as a return to form for the series.
