An unknown virus hit the earth and began to turn people into monsters. Those who did not turn up were faced with the problem of survival in this world. Most of the benefits of civilization are destroyed and people are forced to fight for their lives every day. You find yourself in a small town, hoping to find groceries. To get to the right place you need to clear the path from monsters. Kill all the monsters to survive.
