Project Zomboid is an open-world, isometric video game developed by British and Canadian independent developer The Indie Stone. The game is set in the post-apocalyptic, zombie-infested exclusion zone of the fictional Knox Country (formerly Knox County), Kentucky, United States, where the player is challenged to survive for as long as possible before inevitably dying. It was one of the first five games released on the alpha funding section of the gaming portal Desura.
In 2011, The Indie Stone were subject to a high-profile setback within the indie gaming community following the theft of two laptops containing the game's code. Since then, Project Zomboid has appeared on Steam Early Access and continues development to this day. Project Zomboid is The Indie Stone's first commercially released game. The latest unstable release is Build 42, first released in unstable beta in December 2024, which includes animals, a crafting system overhaul, multiple locations added and revamped, alongside other minor changes. Project Zomboid is set in 1993, with the game starting by default on July 9; however, the start date and time can be changed when playing on the sandbox mode.
