In this game you take on the role of Dawn Aran. The first and only know human member of Ridley’s faction. Raised by Ridley from before she can remember he has molded and manipulated her into his ultimate dark operative. Primed yet untested she is sent out on her “zero” mission to retrieve a newly discovered biological specimen in the possession of a Federation research crew orbiting planet SR388. This game is intended as a prequel and takes place just before the original Metroid.
