Survival

Survival games are a subgenre of computer action games that are embedded in vast open worlds, and the player is there to survive in an unfriendly world with limited resources, and its purpose is to search for and collect further resources that will satisfy its basic needs or build needed tools, weapons or shelter.
Many survival production is based on randomly generated environments in which each time the player is cast into a different fragment of the map, so that each game can be dramatically different.
Games of the survival genre often contain elements of horror, in which the main focus is on horror and the player's feelings of fear and loneliness in the world around him.
