Survivalists will be able to explore and hopefully survive The Long Dark's newly added Hushed River Valley region. There'll be no human-made settlements there so players will have to find more creative places to hide from the elements.
The so-called Vigilant Flame survival mode update also brings with it a new cooking system and "buffer memories", which should immerse you further in the experience as well as give you some additional backstory. The update includes a number of other additions and gameplay tweaks, so check out the update trailer more for details.
