The game is set in a huge open world, which has an ominous cycle of day and night. During the day, players will travel through a vast urban environment destroyed by virus outbreaks, look for materials around the world, and make their own weapons to resist the growing number of infected people. At night, hunters become prey, and infected people become more active and dangerous.
