It was also named the ninth-best Game Boy Advance game by IGN. The game received several honors, including a 46th-place ranking in a list of the Top 200 Games compiled by Nintendo Power. Zero Mission received acclaim for its new content, graphics, gameplay and improvements over the original, though it received minor criticism for its short length. The remake adds items, additional areas, mini-bosses, difficulty levels and a rewritten story that explores Samus's past. The gameplay focuses on exploration, with the player searching for power-ups to reach previously inaccessible areas. Like other Metroid games, the player controls bounty hunter Samus Aran, who travels to planet Zebes after learning that the Space Pirates are experimenting with Metroids, hostile parasitic creatures. It is a remake of the original Metroid (1986), and retells the story with updated visuals and gameplay. Metroid: Zero Mission is a 2004 action-adventure game developed by Nintendo Research & Development 1 (R&D1) and published by Nintendo for the Game Boy Advance.
