The year that Minecraftia was threatened with nuclear weapons by China, is when Miner Inc. started building underground shelters for the civilians of Minecraftia who didn't want to leave the MC. Some didn't work too great though, Shelter 33 was eventually overrun by Giant Spiders. Shelter 54 was the first shelter to be finished by Miner Inc. Miner Incorporated's main focus is to gather Earth's natural recources and make something out of it, like weapons, tools, the Shelters, and many other things.
