Metroid Fusion: C.L.E.A.N. Station

While flying through space with her ship, Samus suddenly received an order from a strange witty AI. It turns out the AI controls a huge space facility called C.L.E.A.N.S. . The station is invaded by strange "dirty" lifeforms. Samus now has to put an end to this, so biological research can be conducted on the ship once again.
