I should learn how to mod Lethal Company and add my shoes as a moon you can visit.

Fire exit is some random hole poked through at the toes

Outside terrain is a labyrinth of the prints left behind by the treads

Inside I'll have to figure out still

@Oric Items that your feet have picked up and now discarded into your shoe. The insole likely to be pounded down, so would make for quite a challenging trek.
@DylanBun very foggy too... now I'm thinking of having the map include various amounts of rubble from ex-civilizations that ended under foot
@Oric Heck yeah! A fog covers the entire map, some members of ex-civilizations still around, as well as smaller macros that got caught between toes.
