Simulator Z

Simulator Z is a large-scale sandbox simulation where you control a zombie outbreak, command survivors and watch battles unfold. Place humans, zombies, military units, vehicles, defenses and environmental objects throughout the world to build survivor camps, unleash hordes, stage battles or test who survives. Simulations can range from small encounters to city-wide outbreaks, with hundreds or thousands of active units.

The battlefield

Each unit has a role: civilians flee from danger, soldiers fight back, medics support survivors and vehicles carry troops across the battlefield. Heroes and specialized zombies add further units and threats, with multiple zombie types that have different strengths and abilities. Units continue to fight and react even when they are outside your camera view. You can place walls, doors, lights, barricades, mines and other structures, select and move units, and fast-forward through large battles. The simulation includes a day-and-night cycle and persistent unlock progression.

Game modes

Freeplay gives you control over the simulation without traditional objectives or restrictions. You can build settlements, place barricades, deploy armies and release zombies to create your own scenarios.

In Thrive Mode, you defend a generator against increasingly dangerous waves of zombies. Between rounds, spend coins to deploy survivors, build defenses and repair the generator. Each wave brings stronger and faster enemies; survive as long as possible and set a personal record.

Cooperative multiplayer

Two players can control the same living battlefield together. Place units, build defenses, move troops and create zombie scenarios cooperatively.
