The city was flooded with zombies, the virus spread so quickly that almost no healthy people were left. You were saved only by the fact that you have experience in combat operations and keep your sniper rifle ready at all times. At home is unsafe, neighbors have already turned into bloodthirsty monsters and are hungry to suck your brain. Although, in fairness, it's worth saying that as people, they did not seem better. The highest point in the city is the roof of the town hall. Climb up and take a position. The horde of zombies is already moving in your direction. Point and shoot, do not let the dead cross the red line, this will mean your death in the game Kill All Zombies. The fate of the surviving citizens is in your hands.
