I made a vague schematic of what I knew about the complex so far. Large structure on the surface, storage shaft below, lots of unknown space in the middle. I applied 2.0’s channel annotations and saw the section that it had marked as targetControlSystem’s must be in the upper levels and the surface structure. The shaft was cut off from comm and feed signals, and the UnidentifiedSender’s section was above the shaft, and reached up into the center part of the complex, woven in with TargetControlSystem.
