The "As the Dead Sleep" Challenge is difficult but certainly do-able; it is set to Interloper Difficulty, has no time limit, the 5 Graves can be accessed in any order, and all healing except Stims is disabled. This incentivizes reaching all 5 Graves ASAP with minimal backtracking, but 'indefinite' survival is also possible as in a normal Interloper Survival mode save (albeit with finite healing).

Please note: the "Secret Path" shortcut in Bleak Inlet (which allowed significant time saving by avoiding a Scrub Bush wall, and taking a more direct route to the BI exit cave) has been patched out.

Some tips are: -light Campfires with a lit Torch whenever possible, to conserve Matches -pull and extinguish Torches from Campfires until you have several high durability ones, and 'daisy chain' them together to transport fire and stay warmer while traveling -harvest Rose Hips and Reishi whenever possible en-route for food/water, and drop them on the ground near a lit campfire, to warm them and consume when you're cold to get the "Warming Up" buff -Stims tend to spawn in very specific places. Sleep can largely be avoided during the challenge by carrying minimal weight, traveling non-stop, performing as few time-passing actions as possible, and using Stims to climb essential Climbing Ropes. -At least one Climbing Rope is necessary to reach the Grave in the Ravine, it can be found by looting but is most often taken from a pre-existing deployed rope (e.g. after climbing up from MT, and heading into ML).

As of April 2020, the current fastest route is: (BI) Fallen Lighthouse -> (BI) Residences -> (BI) Washed Trailers -> Cave -> (Muskeg) OSFH, (BR) Maintenance Yard (Grave #1) -> (Muskeg) Milton Transition -> (MT) Hermit's Cabin -> (MT) Trailer -> Cave -> (HRV) Many Falls Vista (Grave #2), (MT), (MT) Picnic Area Office, Cave, (ML) Trapper, (ML) Hydro Trailers, (Ravine) Ravine Basin (Grave #3), (ML) Carter, (Winding River), (PV) Signal Hill, (PV) Homestead, (PV) Preppers, (TWM) Crystal Lake (Grave #4), (PV) Mine, (CH), (Highway), (DP) Riken (Grave #5)
