Terminal 5: Shutdown (Rally Point - Delta)
After entering the production tower (third LZ for your Pelican) in an attempt to reach the Spire controls, Cortana will place a waypoint. Instead of turning right and heading for it, continue forward to the structure at the back of the large room. On the far side of said structure, you’ll find a terminal. If you’ve encountered the Hunters, you’ve gone too far and need to turn back.
