The world has changed after the explosion at one of the secret laboratories. They experimented on people there, creating universal soldiers, but instead zombies appeared. One of the laboratory assistants accidentally broke the flask with the virus and infection began. The laboratory was deep underground, but this did not save anyone and the virus broke out to the surface, mowing people and turning them into zombies, and not only people, but also animals and even birds, in general, all life on the planet. Those few survivors, which include you in Zombie Survival Gun 3D, have to fight for existence. Every day is a battle for survival, in which one cannot make a mistake, because it costs a life.
