Police Stories: Zombie Case – an addition to the shooter based on tactics and strategy. The player finds himself in a city where horrific riots begin, and the crime rate has risen to unprecedented heights. Civilians constantly send complaints and call police stations with stories about seeing people who look like walking dead. Some of them try to bite passers-by or kill them.

The story follows partners John and Rick. The main characters, police officers, have to find out whether it is a drug or a real zombie virus, because of which the whole world will go into chaos. They need to save civilians, fight deadly opponents and save law and order. DLC Zombie Case offers 5 new tasks with additional tactical elements, opponents and ways to achieve victory in battles with monsters.

Zombies are aggressive, attack the first people they meet and are not afraid of the sounds of gunshots. Law enforcement officers give them commands, but they do not obey them. In order to stay alive, the central characters shoot at criminals to kill. A single bite will turn a person into a zombie, acting only on their instincts. The user can find their own approach to passing, attack enemies with a butt, use electric shock, gas spray or other weapons that have their own effectiveness.
