Super Metroid is the third game in the Metroid series and is the successor to Metroid II: Return of Samus. In it, Samus answers a distress call at the Space Colony Ceres. She finds that the station is deserted, and the researchers are dead. When she locates the Metroid Hatchling, she finds that Ridley has taken it and gives chase. Super Metroid improved on the formula established in Metroid and Metroid II: Return of Samus.
