Metroid

In the year 20X5, a dangerous new life form is discovered on the desolate Planet SR388. Before research scientists can safely bring it back for study, it is stolen by a group of space pirates. This life form, named Metroid, could make a deadly biological weapon if used improperly.

After several unsuccessful attempts to infiltrate the pirates' headquarters on Zebes, the Galaxy Federation unleashes their final plan of attack: Samus Aran, one of the galaxy's best bounty hunters. Armed with cybernetic armor and an arm-mounted laser rifle, Samus is charged with the task of navigating the maze-like corridors of the base and destroying Mother Brain, the pirates' leader.

Samus begins with 30 units of energy and no energy tanks....
