Full Below and Beyond
Enter Game Rule Full Below and Beyond. Do you want to hide underground and take all the most valuable things there? Organize an eternal backup site with living colonists on an asteroid? Build underground domes and asteroid mining buildings right on the surface? All this is in this mod. All this will come in handy if you play for example with such mods as Play All Mysteries from ChoGGi where you are always attacked by misfortunes.
