About this game
Zombie Simulator Z is a large-scale sandbox simulation where you control the outbreak, command survivors, and watch entire battles unfold.
Create your own zombie apocalypse by placing humans, zombies, military units, vehicles, defenses, and environmental objects throughout the world. Build fortified survivor camps, unleash massive hordes, stage military battles, or simply experiment and see who survives.
Every unit has its own role. Civilians flee from danger, soldiers fight back, medics support survivors, vehicles move troops across the battlefield, and specialized zombies bring new threats to every simulation. Both sides continue fighting and reacting even when they are outside your camera view.
Freeplay Mode
Freeplay gives you complete control over the simulation. Build settlements, place barricades, deploy armies, unleash zombies, and create your own scenarios without traditional objectives or restrictions.
Thrive Mode
Thrive Mode challenges you to defend a generator against increasingly dangerous waves of zombies. Spend coins to deploy survivors, construct defenses, repair the generator, and prepare between rounds. Each wave introduces stronger and faster enemies—survive for as long as you can and set a new personal record.
Multiplayer
Play together with another player and control the same living battlefield. Place units, construct defenses, move troops, and create zombie scenarios cooperatively.
Features
Large-scale battles with hundreds or thousands of active units
Humans, zombies, heroes, vehicles, helicopters, defenses, and explosives
Multiple zombie types with different strengths and abilities

Cooperative two-player multiplayer
Day-and-night simulation

Create anything from small encounters to city-wide outbreaks
There is no single correct way to play. Build a safe haven, recreate humanity’s final stand, overwhelm the world with zombies, or sit back and watch the chaos unfold.
You create the apocalypse. You decide who survives.
