I awake on the Medical Center of Citadel Station and find myself surroundet by medic-robots controlled by the ships AI called S.H.O.D.A.N.
And I find out that everything was my fault. It looks like that I am the only survivor. My only contact is a woman called Rebbeca Lansing. She told me that S.H.O.D.A.N. is planing to destroy Earth with the Laser-Cannon of the Station. But first I need to leave the Hospital Deck.
