Just Survive was a survival massively multiplayer online game developed and published by Daybreak Game Company for Microsoft Windows. 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. 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 released in early access in January 2015, selling over a million copies within two months, before being discontinued in October 2018. The gameplay of Just Survive emphasized multiplayer cooperation, trading, and team-building. Players scavenge supplies, craft items, and build strongholds to defend against the zombie horde. 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.
