DayZ is a multiplayer open-world survival horror mod created by Dean Hall for the 2009 tactical shooter game ARMA 2 and its 2010 expansion, ARMA 2: Operation Arrowhead. Set in the fictional post-Soviet nation of Chernarus, the mod immerses players in a world ravaged by an unknown virus that has turned much of the population into aggressive zombies. As a survivor with few resources, players must search the environment for essentials like food, water, weapons, and medical supplies, while fending off or evading both zombies and other players, and occasionally non-player characters, in a desperate bid to endure the zombie outbreak.
