There are sandbags on the street, and behind them is a brave warrior in a helmet and body armor in Zombie Defense GO. He is placed to protect a piece of the street and not miss the zombies that are already moving in his direction. In the upper right corner you will see the number of zombies that will be counted in this attack wave. In the lower left corner, money will accumulate for each destroyed zombie. Move the hero using the up or down arrows and shoot the zombies. When you have accumulated enough money, go and buy a shotgun instead of a pistol, and then a submachine gun, and so on. At the bottom, you can change weapons by pressing, because zombies are also different in Zombie Defense GO.
