Earlier this month Bethesda tweeted about up and coming shifts to the way that the survival mode is going to function in Fallout 4 and now the details of those changes have been leaked.
Survival mode is no longer just more difficult it’s almost a whole new game, Details listed below.
Manual and quicksaving are disabled. To save your game, you’ll need to find a bed and sleep for at least an hour.
Combat is more lethal for everyone. You now deal, but also take, more damage. You can increase the damage you deal even further with “Adrenaline” (see below).
- Fast Travel
Fast Travel is disabled. If you wish to be somewhere, you’ll have to physically travel there.
- Weighted Ammo
Bullets and shells now all have a small amount of weight, which varies by caliber. Heavier items such as fusion cores, rockets, and mini-nukes can really drag you down.
Be sure to keep your eyes peeled, as enemies will no longer appear on your compass. As well, the distance at which locations of interest will appear has been significantly shortened.
Survival automatically grants the Adrenaline perk, which provides a bonus to your damage output. Unlike other perks, the only way to increase your rank of the Adrenaline perk is by getting kills (hostile or otherwise). The higher your Adrenaline rank, the higher the damage bonus. Sleeping for more than an hour, however, will cause your Adrenaline rank to lower. You can check your current Adrenaline rank at any time in the Perks section on the Stat tab in your Pip-Boy.
