 Samus Aran, interstellar bounty hunter, is flying in her gunship one day when she recieves a strange distress signal from an unknown vessel. She goes to intercept the call and ends up on a vessel that has been abandoned. Samus enters and finds that the vessel is filled with space pirates-but they are all either dead or dying. Some pirates evacuated, but Samus does not chase them. All throughout the ship, horribly mutated life forms are floating in tanks and sealed behind doors. When Samus finally enters the reactor core, a gigantic creature called the Parasite Queen jumps out and attacks! Samus destroys the beast, but the battle damages the core and Samus flees for her life. Along the way, though, she encounters...something (I won t give it away!). This something gets out of the ship. Samus decides to pursue it and they end up on Tallon IV, a planet once inhabited by the Chozo race. Samus begins her quest to find her foe, but ends wrapped in a web of corruption, mysterious artifacts, and a strange material that could endanger the galaxy! Can Samus rescue Tallon IV and defeat the Space Pirates?
