DeadOS is an indie game developed by Benn Powell, focusing on a realistic simulation of a zombie apocalypse. Inspired by cutscenes from Resident Evil 3, Powell aimed to explore the moments typically overlooked in zombie narratives. The game allows players to manipulate various parameters, such as city size and population density, to observe the consequences of different outbreak scenarios in a procedurally generated 3D cityscape. The simulation initially featured a simple infection model but became more complex with the addition of weapons and law enforcement, affecting human behavior during the outbreak. Players can guide characters through the chaos, engaging in actions like fighting zombies and scavenging for supplies. After nearly seven years of development, Powell plans to enhance the game further, including features for player-designed cities and community-created content. He aims to create a detailed zombie outbreak simulation, likening it to the Dwarf Fortress of undead scenarios.
