Editing Lone Echo Speedrunning Guide (section)

==== Oxygen ====
When you get back to the room with Liv, close the door behind you and go to the terminal to activate the oxygen. As soon as you do this, go back to the tunnel you came from and clip out to the left of it (just like the oob above). Fly underneath the room towards the large door that will open after they give up with the oxygen. After a tiny bit, fly down and out of the mission area to respawn. You want to remain up long enough to hit a checkpoint that is near that large door (rather than heading down right away). You should respawn outside the large door. First, open the door with the lock on the outside, then open it again with the lock on the inside. This should call the Fury. Go to the Fury and enter the destination. Now go back and activate the lock on the outside. After a short bit, Liv should say “... let’s go,” at which point you can fly out of the mission area to respawn.
