For legions of Metroid fans, Samus Aran is a true hero. Gamers old enough to remember the original Metroid will never forget their surprise when learning that the armored character they had been controlling for days on end was actually a woman! Of course, you were only let in on the secret if you were able to beat the game in less than three hours -- no easy task.
The original Metroid premiered on the original NES in August of 1986. Gamers had to wait until November of 1991 for another adventure starring Samus, when Metroid II: Return of Samus was released for Game Boy. The ultimate tribute to alien annihilation came to the Super NES in April of 1994, in the form of Super Metroid. When it was released, Super Metroid was the largest Super NES game ever made, weighing in at a hefty 24 Megs.
