The program starts with the operative waking on the surface with a headset allowing communication with their operator, and small spider-like Machines crawling over them. They must walk to the fetus fields, find the pod (unless one is taken at random) and remove it from the structure of feeding pipes it is attached to. Avoiding the Harvesters, they must then go to a waste funnel and send it to the tunnels from where they could be retrieved by their hovercraft.
