On Interloper cars are still incredibly useful, but you must use them for the last 3-4 hours of the day and the first 2-3 hours of night when temperatures are the highest (a little before and after sunset).
The Mountaineer's Hut in Timberwolf Mountain, abandoned lookouts in Mystery Lake and Coastal Highway and the porch on the Pleasant Valley Farmhouse count as "indoors" for cabin fever. Spending 3-5 hours a day in cars sleeping, repairing, or simply passing time is enough to stave off cabin fever forever. Cars give a +5 degree temperature boost but stop wildlife attacks, and on the easier difficulties are all you will ever need to battle cabin fever. Snow shelters give a +15 degree temperature boost but should only be used where the player is sure no wolves patrol as they do not stop wildlife attacks. Both methods allow you to sleep outdoors even without a bedroll through the campcraft section in the radial menu (hold spacebar). The third way to battle cabin fever is to sleep in cars or snow shelters. Interloper players beware, even with complete fur clothing and dual bearskin coats, it is possible to freeze to death in a cave if you get a blizzard during late night/early morning when temperatures are the coldest. Spending a day in a cave once out of every 6 days is more than enough to eliminate cabin fever. These give a +15 degree temperature bonus and with good late game clothing a player can stay warm in these 24/7 without any fire whatsoever. The second and by far the easiest method for dealing with cabin fever is to spend a day in the back of a warm cave. It gives early game players a source of parasite free food while boiling plenty of water - a task that all players must do at some time during the week anyway. This method works on all difficulties, requires the most effort, but has the most benefits.
The first and most common way is to gather firewood and spend a day in a fishing hut. Cabin Fever risk can be dealt with in a number of ways, even on interloper.
To treat cabin fever, the player must spend time outside until it goes away and cannot sleep inside for 24 hours. The only symptom of cabin fever is that the player cannot rest inside for 24 hours. In Interloper difficulty, you can start developing Cabin Fever after the first 10 days. There is a 25-50 day grace period where this cannot happen, as this would only become an apparent problem long after having survived for a long time. Cabin fever is an affliction that was added in the 'Tireless Menace' update.Ĭabin fever is only dangerous when having spent most of six days inside a building.
