text: While fending off a Space Pirate assault , Samus and her fellow bounty hunters are attacked by her doppelgÃ nger , Dark Samus , who incapacitates them with a mutagenic material called Phazon . After Samus loses contact with the other hunters , the Federation sends Samus on a mission to determine what happened to them .
simplified: Samus takes the keyboard of the control pad , and then Dark Samus attacks the bounty hunters , but Samus survives , as does the rest of the bounty hunters .
