Chapter Summaries

Yinsen defeated the Engineer with magic, put him to sleep, and decided to explore the alien ship for technology. He confirmed that the vessel used anti-gravity, which could make building and launching large spacecraft far easier.

• The Engineer killed Weyland and dismantled David, then attacked the humans as their weapons failed to pierce his suit.
