Survival game

Survival games are a subgenre of action games which are often set in hostile, intense, open-world environments. Players generally start with minimal equipment and are required to survive as long as possible by finding the resources necessary to manage hunger, thirst, disease and/or mental state. Many survival games are based on randomly or procedurally generated persistent environments; more recently, survival games are often playable online, allowing players to interact in a single world. Survival games are generally open-ended with no set goals and often closely related to the survival horror genre, where the player must survive within a supernatural setting, such as a zombie apocalypse.
