The Long Dark is a first person, single player survival game set in a snow covered Northern wilderness. The game is a purely sandbox experience without story elements. The player instead simply lands in the middle of a desolate snow covered rural area completely alone, and is expected to immediately start battling the elements in order to survive.
The gameplay consists of exploring the five interconnected maps of the game world in search of shelter, equipment and resources, while managing the character's basic needs (hunger, thirst, body temperature, fatigue, encumbrance, health) and avoiding dangerous animals. The available equipment that spawns in the maps is randomized.
The main features of the gameplay include managing the player's inventory, crafting items (tools, food and medication), repairing most equipment and clothes through a crafting system, and hunting for food with a bow or pistol/rifle, dependent on finding ammunition. A basic stealth system allows players to avoid detection by wildlife.
With a day-night system, dynamic weather and an animal AI that tries to simulate real behaviour, the game attempts to mimic a survival experience in a natural environment with some degree of realism. However, the amount of available wildlife is limited, making the player's survival depend on their ability to manage resources and fend off hostile elements.
The Long Dark differentiates itself from other survival games by pitting the player against nothing but a hostile natural environment, with a focus on atmosphere and exploration over combat and challenge.
