NightZ.io is an exciting multiplayer io game in which you have to survive in the apocalyptic world among hordes of hungry zombies. To start, select easy or medium difficulty in the column, enter a nickname and press "Enter". Once at the location, run to collect resources. Chop trees, get stones. When the yellow bar at the bottom fills up, you will level up and unlock new tools and weapons. For example, shield, bow, metal discs. To protect yourself from zombies, build a fortification around the source of resources: lay out stones around the perimeter to cut in the center. Click on the stone on the panel below, and then on the place where to put it.
