Set after the events of Metroid, Samus Aran lands on the planet Tallon IV. Sent here by a distress signal, She investigates more experiments designed by the Space Pirates, including a corrupted mutating substance known as Phazon. While there she'll have to face new and old enemies such as the Parasite Queen, and her rival cybernetically resurrected as Meta-Ridley. As she explores the planet’s ruins, Samus slowly uncovers her Chozo upbringing, begins to emotionally reawaken, and embraces both her humanity and her alien heritage.
