Abandoned mine (game location)

An old abandoned mine for extracting a rare mineral. The largest location in the game, by the way! The original map will be much darker, and light sources have been added only for demonstration purposes. There are several separate caves and tunnels, a railway for mine cars, a broken tunnel boring machine stuck in a passageway, a crowded warehouse, a regular warehouse, a cave with mushrooms, and much more.
