The tube curved ahead and, as I’d suspected, I saw the shadows and light play that indicated big windows in both walls. What we were about to do was an obvious tactic, and the combat bots could have sent some miniature drones up here to see if we tried it. But I wasn’t picking up any hint of surveillance, movement, or suspicious static on my scan. It was support for the theory that they didn’t have an on-site controller; the schematic didn’t show that these access tubes had windows, it had just seemed likely given the rest of the facility’s design. That wasn’t something a combat bot was going to pick up on.
