What really happened to Hadley’s Hope on LV-426 before the Colonial Marines arrived?

Before the events of ALIENS, Hadley’s Hope was a thriving colony. Then it went silent.

In this cinematic Alien lore documentary, Dark Archives reconstructs the fall of Hadley’s Hope — from the first discovery and Xenomorph outbreak to Newt’s survival, the hive beneath the atmosphere processor, Weyland-Yutani, and the arrival of the Colonial Marines.

By the time the USS Sulaco reached LV-426, Hadley’s Hope was already lost.
