No. 4 Division gets to the main ship, but finds they've walked into a trap. The Chinese division has betrayed them, and wants the two post-surgery humans as experimental samples. The Chinese have brought weapons, which they use to slaughter the Terraformars by the hundreds.

The heroic sacrifice of the civilian crew allows No.1 and No. 2 division to temporarily take back control of the communications tower. But the last member of the crew passes out before she can tell Earth about No. 4 division's betrayal. Is all hope lost, or is there another way?
