DayZ is open-world survival horror hybrid-MMO video game. The much hyped follow-up to the award winning mod of the same name. Development in 2012 when the mod's creator, Dean Hall, joined Bohemia Interactive to commence work on the standalone version of the game. The development has been focused on altering the engine to suit the game's needs, developing a working client-server architecture, and introducing new features like diseases and a better inventory system.

The game places the player in the fictional 225km2 post-Soviet state of Chernarus+, one of the areas hit by a new and presently unknown infection which has wiped out most of the world's population. The player is one of the few who have survived and now must scavenging the world for food, water, weapons, and medicine, while killing or avoiding infected, and killing, avoiding or co-opting other players in an effort to survive as long as they can in the harsh post-apocalyptic landscape.
