Unturned is an open-world survival sandbox game where players assume the role of a survivor, dropped into the zombie-infested ruins of modern day society, and must work with friends and forge alliances to remain among the living. Players must search out supplies such as clothes, food and weapons, as well as scavenge for resources like wood and metal to create strongholds and defenses to fend off the zombie horde. Survivors must also keep an eye on their health by finding food and water as well as checking on radiation levels.
