Subterrestrial Mod 1.8.1 introduces new structures that can only be created underground. Although these mysterious structures have been around for so many years, few people have ever discovered the treasures inside. There are currently at least 12 types of these underground cabins, and they can be found all over the world. These cabins are available to players who do not know about them. However, this could mean that they miss out on huge opportunities to become wealthy and famous. Although they are randomly generated, the interiors of these cabins are intricate and beautiful. This creates a new level in immersion unlike anything else. The adventurers will feel the thrill of the Subterrestrial again.
