To do so I need to be inside the Hyperion building.
I was inside but got killed.
Then I respawned outside.
Before I got in by injuring Loaders and then Engineers opened the doors.
Now nothing seems to open the doors and I've spent three nights wandering around outside the building with no aparant way to get in.
Nothing on YouTube is helpful. All the videos assume that you got in the first time.
Anyone have any idea how to deal with this?
