Our take on DeadOS

The defining detail is direct control over any individual during an active outbreak, allowing a scenario to shift between observing the city and controlling one survivor or infected character.

What is DeadOS?

DeadOS is an early-access game about simulating zombie outbreaks in city-sized sandbox settings.

Set conditions from the start of an outbreak to its conclusion, adjusting factors such as zombie speed, human accuracy, ammunition, and other variables. A city can include up to 25,000 simulated people spread across as many as 900 blocks. At any point, take control of an individual, whether that person is still alive or infected. Create custom city blocks to alter the environment, and change the simulation speed to suit a machine’s performance. Scenarios can range from slow-moving groups of zombies to infections that spread rapidly. The game uses a retro visual style.
