In Yorg.io, you have to gather resources by mining raw materials and refining them. Build a base, some mines, refineries, and factories. You'll also have to build cannon towers and other armed guards around your base of operations because once the sun goes down, the zombies will appear. They will try to tear down your factories to get to the workers inside. Can you protect your buildings from the zombies? Every 10 waves, a powerful zombie boss will appear. Build city walls to buy time, and upgrade your buildings to keep up with the increasing strength and numbers of your enemies! Unlock all the branches of your Skill Tree to survive!
