Metroid: Samus Returns is an action-adventure game developed by Nintendo EPD and MercurySteam, and published by Nintendo for the Nintendo 3DS in 2017. The game is a remake of the 1991 Game Boy game Metroid II: Return of Samus. Players control bounty hunter 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.
