Samus returns in a new mission to unravel the mystery behind the ruined walls scattered across Tallon IV. Samus enters a mysterious derelict ship on the unexplored world to investigate Space Pirate activities. She has thwarted their dastardly efforts before. She stopped them from amassing an army of Metroids and she kept Mother Brain from retrieving the last known Metroid larva. Now she must face the Space Pirates once again in an all-new adventure. It’s up to you to explore the world and recover more power-ups and weapons, which gradually open more gameplay areas.
