Mod:DUST Survival Simulator/The Long Dark

The Long Dark is a labyrinthine and heavily booby-trapped network of hallways connecting Vault 74 to Zion Canyon and Grand Staircase Escalante. It was incorporated into Vault 74 as an emergency escape route in the event of the vault being compromised and leads out into numerous locations that were assumed by Vault-Tec to experience a minimal amount of damage in the event of a nuclear exchange.

Access
The long dark is accessed through the Pine Creek tunnel from Zion Canyon after the key has been recovered from the NCR garrison there.

Pine Creek Tunnel
Pine Creek tunnel is an access route containing a high number of improvised explosive devices and a modest amount of supplies. A maintenance room left of the entrance contains the remains of Waking Cloud which provides an account of the Zion Tribals exodus to the Divide and their subsequent massacre, the blame for which she places on Daniel of New Canaan. Further on is the tunnels normal point of termination and the entrance to the Long Dark, again located to the left. Great Care should be taken here as the booby traps are not readily visible and are easily capable of killing a survivor with almost no warning.

The Long Dark
The long dark is a connection of switchback hallways with most doors either collapsed or otherwise inaccessible. Upon entering the long dark, a survivor will first encounter a locked door leading to Grand Staircase national monument. Immediately to the left is a staircase descending into the long dark proper. Explosives and bear traps are endemic here and the labyrinthine nature of this area makes it very easy to become complacent and wander into a trap you would have otherwise noticed. Eventually, a survivor who avoids the traps will come to a second descending stairway leading to a straight hallway with two doors on either side about halfway through its expanse. The leftmost of these leads to Vault 74.

Vault 74
The door from the long dark opens into what remains of the Vault overseer's office. Among the rubble is a file cabinet containing an overseers journal entry as well as a map of an key to the Grand staircase escalante exit encountered previously. This door can be taken to NCR territory and thus, safety. Proceeding into the vault reveals that it is in ruinous condition, with vault dweller logs indicating that the vault was breached by White Leg tribals sometime after 2081 during their own flight from Zion. The skeletal remains of its residents can be found in the vaults atrium, most located around a jukebox playing Vera Keyes "Begin again". Past this gory spectacle is the Vaults maintenance wing and the main vault door, which has been opened and leads out into the divide.

Insanity
An insane wanderer will experience auditory hallucinations of the Wendigos cry while navigating the long dark, Most instances of this seem to occur when encountering a dead end.

Near the main entrance of the vault, an insane wanderer will encounter two identical men wearing pip-boys and pajamas and boasting green liberty spikes. The significance of these men is unknown though it can probably be assumed that they were among the vault residents massacred by the white legs. They explode in the usual manner when attacked.

Trivia
Vault 74 exists in the base game and serves as a tutorial area for using the GECK editing software. Here, it is occupied by fiends and appears in much less dilapidated condition than it's DUST counterpart. There is nothing analogous to the long dark in the vanilla games version of Vault 74.
