The only survivors were Elizabeth Shaw (Noomi Rapace) and the still-working decapitated head of David the android (Michael Fassbender).
According to The Wrap, at 20th Century Fox’s CinemaCon presentation, new footage of Covenant was shown, and it at least shows what happened to David.
Following that were two spinoff films — Alien vs. Predator and its sequel — where both franchises combined and brought the fight to Earth.
Prometheus had a number of homages to the original movie, including having a female protagonist and an untrustworthy android with secret orders that endangered everyone.
