We came back for the crane, but the mission did not go according to plan. Already aware of the dogs and guards, we were a lot more efficient navigating the industrial ghost town. We reached the crane with time to spare as I wanted to climb with less light on us, but we realized light was not our biggest issue. There was no way of reaching the crane from the platform we were on. We noticed that the only way up was at the bottom, right next to the dogs and guards. Had two options - climb the crane and get caught, or vacate while it was still bright enough to navigate the complex terrain.
