Just recently, Minecraft managed to clear the zombies, but they returned again to take revenge for the loss. There are more of them and the dead became noticeably faster in PGA 6 Pixel Gun Warfare Zombie Attack. Move to positions in the city center. As soon as the zombies see you, they will run towards you and fast enough to attack. Your weapon is not long-range, so you have to let the enemy get closer. But the more zombies you destroy, the faster you can upgrade your weapons. You will find boxes in locations, as well as first-aid kits, which will be free, unlike weapons in PGA 6 Pixel Gun Warfare Zombie Attack.
