On the planet Zebes, Space Pirates and their leader, the Mother Brain, are about to be caught out by the only hero that can stop them, Samus Aran. With a battle suit filled with powerful weapons and the ability to pull off amazing special moves, Samus must use all of her power to take down the Pirates and their leader.
The planet itself is filled with enemies, traps and deadly terrain. Using Samus' Grappling Beam, and other nifty items, you can traverse the landscape, while morphing into a
fast ball device allows Samus to travel into hard to reach places. Power-ups also litter the levels, each helping Samus either with improvements to her weapons or her defensive output.
