In the near future, the Delphi Corporation establishes a lunar mining outpost called the Cradle to harvest lunafilament, a material essential for their revolutionary 3D printing technology. When communications with the facility go silent, systems engineer Hugh Williams is sent to investigate. Upon arrival, he finds the station abandoned and its AI administrator, IDUS, has turned hostile. Rescued by a child-like android named Diana, Hugh must fight his way through the Cradle's robotic workforce to uncover what happened and find a way to send a distress signal back to Earth.
