Plot Elements

 * Space Pirates attack a Galactic Federation-owned space research vessel and seize samples of Metroid creatures. Dangerous floating organisms, Metroids can latch on to any organism and drain its life energy to kill it.
 * The Space Pirates plan to replicate Metroids by exposing them to beta rays and then using them as biological weapons to destroy all living beings that oppose them.
 * While searching for the stolen Metroids, the Galactic Federation locates the Space Pirates' base of operations on the planet Zebes. The Federation assaults the planet, but the Pirates resist, forcing the Federation to retreat.
 * As a last resort, the Federation decides to send a lone bounty hunter to penetrate the Pirates' base and destroy Mother Brain, the mechanical life-form that controls the Space Pirates' fortress and its defenses. Considered the greatest of all bounty hunters, Samus Aran is chosen for the mission.
 * Samus lands on the surface of Zebes and explores the planet, traveling through the planet's caverns. She eventually comes across Kraid, an ally of the Space Pirates, and Ridley, the Space Pirates' commander, and defeats them both. Along the way, Samus finds and destroys Mother Brain. However, while Samus leaves the planet in her gunship, it is attacked by Space Pirates, causing it to crash back onto Zebes, near the Space Pirate Mothership.
 * With both her Gunship and Power Suit destroyed, Samus gets quickly found and captured by a pirate patrol. She is kept prisoner inside a pirate complex, but a sudden Metroid breakout allows her to escape her cell and evade her captors, despite being just equipped with her Zero Suit and a stun gun.
 * Free from captivity, Samus then infiltrates the Mothership, eventually leading her to Chozodia, where a Chozo Statue offers her a trial. Upon passing the trial, Samus is rewarded with a new fully upgraded Power Suit.
 * Continuing to explore the Mothership, Samus eventually reaches the Ridley Robot, a robot built in the likeness of Ridley. After defeating it, Samus escapes the planet using one of the Space Pirate's shuttles, while the Mothership self-destructs.
 * Post-Credits Scene: Samus discovers a weird box hooked-up to her TV set, along with a cartridge that reads "Wanna Play?" Curious, Samus puts the cartridge into the box and flips the switch on...just as the screen cuts to black.
