Metroid is a platform adventure game where you play Samus Aran, a bounty hunter with a mission to destroy Mother Brain. Mother Brain has infested the planet Zebes with a life form called Metroid, a very deadly alien creature capable of massive destruction. You will have to explore several areas on the planet in order to find all the power ups and missiles you'll need to complete that task. Bosses Kraid and Ridley will have to be vanquished as well.
