Sunlight and shelter
The official description makes sunlight a central threat after a planetary catastrophe. Huge concrete structures provide shelter across the abandoned cities and megastructures. Plan the next covered part of a crossing before leaving shelter. The source establishes the shelter principle, not a safe exposure timer or a quantified damage rate.
First route and the closed metro
Capn’ Cattlehammer’s community walkthrough starts by leaving the opening hole and following the pipeline toward the city. Look for the blue M to find the metro after receiving N3’s instructions. The closed door is a progression checkpoint: the guide next seeks access to the Sphere through the unfinished Agglomeration 5 building across from it. The old railway is the author’s shaded navigation aid.
