Metroid: Zero Mission

Sent to Zebes to investigate rumors of a deadly alien species, Samus meets her match in the form of the mysterious Metroids -- energy-sapping creatures that emerge from an oversized cerebrum beneath the planet's surface. Samus isn't the only traveler searching for the Metroids. A band of Space Pirates has touched down to extract the curious creatures and use them as weapons. Samus must thwart the pirates, but they are wily and will prove to be more trouble than Samus expects.
