NES Metroid

Metroid is an action-adventure game in which the player controls Samus Aran in sprite-rendered two-dimensional landscapes. The game takes place on the fictional planet of Zebes, a large, open-ended world with areas connected by doors and elevators. The player controls Samus as she travels through the planet's caverns and hunts Space Pirates. Metroid is one of the first games to contain multiple endings. In the third, fourth, and fifth endings, Samus Aran appears without her suit, and for the first time, reveals herself to be a woman.
