Contact with Galactic Federation Weaponry Research Facility "Janus IV" was lost 3 days ago. Three Scout ships sent over to scan the surroundings have been shot down and a disruption field has covered the area surrounding the base, preventing long-range scanners from detecting any further activity.

Galactic Commander Adam Ring, appointed operations chief for the base, has been judged as a rebel to the federation and must be taken into a martial trial.

The base was built over a plasma shaft that goes deep into the planet; spontaneous bursts of plasma energy have been detected on the stratosphere of the planet, indicating possible activity from the base. Also, a class V unidentified spacecraft landed on the base 1 day ago.

Intergalactic Bounty Hunter Samus Aran, you have been assigned a mission: to land on the planet, infiltrate the base and recover sensitive weapon research data. You have been allowed to neutralize any resistance found, including rogue federation personnel.

You are also to recover secret weaponry research sensitive material, which was under development over the four different areas of the base:

   * ATO: Nuclear Research Facility
   * BAC: Biological War Research
   * CHE: Toxic Refinery
   * GEN: Genetics Research Lab

You board your gunship and begin your journey to the planet
