The Space Pirates, merciless agents of the evil Mother Brain, have stolen the last Metroid from a research station, and once again Mother Brain threatens the safety of the galaxy! Samus Aran must don her awesome array of high-tech weaponry to retrieve the deadly Metroid hidden deep within the cave-riddled planet Zebes. Super Metroid features excellent graphics, with a huge variety of enemies and worlds to explore. The side-view action will be familiar to many players, only now there are new weapons and items, including the Grappling Beam, which allows Samus to swing across large chasms, and the X-Ray Scope, which reveals secret passages.
