"Metroid​ (メトロイド, Metoroido) is an action-adventure video game and the first entry in the Metroid series. Developed by Nintendo Research & Development 1 and published by Nintendo, the game was released in Japan in August 1986, in North America in August 1987, and in Europe in January 1988. It was re-released for the Game Boy Advance in October 2004, and for the Wii Virtual Console in Europe in July 2007, in North America in August 2007, and in Japan in March 2008. Following a series of commercially successful video games released by Nintendo in the early 1980s, the company began developing Metroid alongside its sister game, Kid Icarus (1986). Metroid was produced by Gunpei Yokoi and directed by Yoshio Sakamoto, with music composed by Hirokazu Tanaka. Set on the planet Zebes, the story follows Samus Aran as she attempts to retrieve Metroid creatures that were stolen by Space Pirates, who plan to replicate the Metroids by exposing them to beta rays and then use them as biological weapons to destroy Samus and all who oppose them. The game's style, focusing on exploration and searching for power-ups used to reach previously inaccessible areas, influenced other video games, and the varied endings for fast completion times made it a popular game for speedrunning. Metroid was lauded for being one of the first video games to feature a woman, Samus Aran, as the protagonist." Source: Wikipedia, "Metroid_(video_game)," available under the CC-BY-SA License.
