H1Z1 is a Free-to-Play Massive Multiplayer Online (MMO) created by a small development team at Sony Online Entertainment (SOE) running the “Forgelight” engine (Planetside 2), allowing up to 2000+ players to play online in the same server on non-instanced action.
It is a hardcore game taking place in “Anywhere, USA”, is Open World and utilizes a complex crafting system.
In H1Z1 Players must fight in a world inhabited by humans and humans infected with the H1Z1 Virus, better known as zombies.
Your survival will be determined by your skills to stay alive, craft a shelter or base, start a fire before nightfall and gather resources like food and water, food and water could be the most vital supplies you can possess.
You are able to either fight or interact with other players, using trades or building teams. In an interview with Adam Clegg from SOE however, he said that unlike other zombie mmo games the main focus will be on surviving against the zombies through team-work with other players, and not mainly a PvP environment with a zombie backdrop. The amount of resources available to players have been announced on a live-stream to be limited.
H1Z1 was released on Steam Early Access on January 15, 2015.
