In the future, the Galactic Federation and the pirates of planet Zebes are at war. Pirates have stolen an unknown life-form, recently discovered on the planet SR388. The life-form, designated "Metroid", is in a state of suspended animation and, according to analysis, was the cause of the complete destruction of SR388. If the Metroid ever got loose, the alien could destroy countless other systems. It is up to the space bounty hunter Samus Aran to land on Zebes and find her way through the perilous terrains of Brinstar and Norfair, destroy the Pirates, as well as their alien enforcers, Ridley and Kraid, and rid the planet of the alien life form before the pirates complete their plans of world destruction.

Using the cybernetic enhancements of her Power Suit, Samus can use a range of weapons and defenses to destroy the enemy. She can also absorb enemies powers into her Power Suit to increase her defense and chance of survival. Using her weapons and special abilities, she must find her way to the central chamber of Tourian and destroy the Mother Brain, the mysterious leader behind the Space Pirates.

Famicom Disk version

The original Japanese release of Metroid was for the Famicom's floppy disk accessory, which used 3/4" floppy disks instead of cartridges and never made it out of Japan. The main difference this added to the game was that the Japanese release used a file-save system while the western releases had to incorporate a password system.

The existence of this different version only added to the many urban legends that have always plagued the original Metroid (such as the secret worlds, glitches, etc.) and if I remember correctly this specific info took a major part in giving extra credit to the belief that somehow, somewhere, there was a two-player version of Metroid. Why? Because the box of the US release had a typo that advertised it as a two-player game (check out the original back-cover).


The Metroid series was obviously somewhat inspired by the Alien series of films. Among the most visible similarities are a tough female protagonist called Samus Aran (in reverence to Alien's Ripley), and icky alien creatures that try to eat your head. Ridley, one of the two mini-bosses in Metroid, was named after Ridley Scott who directed the first Alien movie. The game parallels other elements from the movie as well, including climactic self-destruct countdowns, egg-hatching extraterrestrials, and a main antagonist named after Alien's 'Mother' computer.

Multiple endings

Metroid has 5 endings depending on the time you take to finish it. After the standard "Congratulations" screen Samus would flash, and depending on your final time he would: 1-Raise his hand to you (over 5 hours); 2-Remove his helmet (3-5 hours); And 3- Remove his armor completely and remain in some sort of leotard (less than 3 hours).

Now, the interesting thing happened on those two last endings since Samus revealed his identity, and showed us that he was a woman all along! This was a major shocker at it's time and a closely guarded secret since at that time these things were very hard to prove and all the documentation referred to him as a He.

Furthermore getting the under 3 hrs ending allows you to re-start the game as an armor-less Samus! (just press start after the credits roll) And ending the game this way over 5 hours gets you a different ending where armored Samus just looks away from you in shame.

The fifth and final ending shows Samus without the armor and dressed in nothing but a skimpy bikini! And to unlock it all you have to do is finish the whole game under one hour.
