THE METROID MENACE

Enter Samus
Bounty hunter Samus Aran was commissioned by the Galactic Federation to eliminate the space pirates and do away with the dangerous Metroids. Samus landed on Zebes alone and carried out her mission with speed and precision. After the skirmish on Zebes, a special corps was assigned by the Galactic Federation to destroy the Meroids on SR388. That corps was never heard from again. The Supreme Council gave Samus the job to fly to SR388 and do what the special corps could not do--make the Metroids extinct.
