Turn on Subtitles/Closed Captions for explanations for this video. Finally got a clean pass through Crucible of Astrid with help from a friend.
This event requires a minimum of two people to complete. In this case my Friend KhaosNinja is activating and deactivating the different parts of the airlock tunnel for me. He does so by placing and removing an echo from the device at the beginning of the airlock.
The main goal here is to Get echoes into the back of the airlock to activate the laser which activates the panel to expose the Crystal as well as spawn the Valkyrie as seen at the end.
As a tip, it's best that if you run a static group, you have a person designated to control the door for the 1-2 people carrying Echoes.
