Metroid: Zero Mission (メトロイドゼロミッション Metoroido Zero Misshon?) is a remake of Metroid, making it chronologically the first game in the Metroid series and replacing Metroid in the canon. It was designed to "retell the story of Samus Aran's original mission". Zero Mission was developed by Nintendo's internal team, Nintendo Research & Development 1, under the direction of Yoshio Sakamoto. Zero Mission features the same plot as the original Metroid, but is slightly modified with the addition of new areas. It marks the first appearance of Zero Suit Samus.
