In February 2016, Daybreak announced that the game originally known as simply H1Z1 had split into two separate projects with their own dedicated development teams, subtitled Just Survive and King of the Kill. Despite the unstable launch, the game sold over a million copies within two months. A new bug, which made all servers go offline, was also introduced to the game after the developer released a patch to fix other problems. Framerate issues, lack of voice chat and AI problems were also among the problems reported. Players reported that they could not login to their account or enter any active server.

At release, the game suffered from severe technical issues. The game was released on Steam as an early access title on January 15, 2015. The main focus of the game involved surviving against zombies through teamwork with other players, rather than having a player versus player (PvP) environment with zombies as a backdrop. Players scavenge supplies, craft items, and build strongholds to defend against the zombie horde. The gameplay of Just Survive emphasized multiplayer cooperation, trading, and team-building. The game released in early access in January 2015, selling over a million copies within two months, before being discontinued in October 2018.

In it, players attempt to survive against the natural elements such as wolves and bears, hordes of zombies, and thousands of potentially hostile survivors through interaction, scavenging for resources, building shelters, and crafting. The game, originally known as H1Z1 and later as H1Z1: Just Survive, is set during a zombie apocalypse in a rural area of the United States. Just Survive was a survival massively multiplayer online game developed and published by Daybreak Game Company for Microsoft Windows.
