Minor structural concerns, as expected. The mining op that used to be here expanded the natural cave system. Newer sections of the complex were excavated but never reinforced. Goes without saying that you shouldn't make plans for those sections 'til you can put up the creds to make them safe.
The more immediate concern is the life support systems. Those units are fifty years old—a conservative estimate. If the air scrubbers stop working, we die. If the pressure regulators stop working, we die. Artificial gravity fails? We die. You get the picture.
After what we went through in the Blitz, I'm with you all the way. I just need you to tell me to my face you think this is worth it.
