Show the hordes of zombies that your base is not one to be trifled with in YORG.io. Start with only a base, and expand out by building resource-gathering structures and defenses to keep them safe. Watch out when night comes, because that's when the zombies come to munch on your brains.
How to play
There's a great tutorial that will ease you into the game. But basically click structures and place them according to your base layout, and your nearby items.
