Bethesda has made some changes to Fallout 4 Survival Mode. They explain below how they work, though we only added a few of their changes.
Some of the changes to the game in Survival Mode include players not being able to fast travel in order to explore more, saving by sleeping in beds only, and increasing both the damage dealt and taken in combat. Also, enemies no longer appear on your compass to give you a heads-up.
Saving with Sleep: Manual, quicksaving and almost all autosaves are disabled. To save your game, you’ll need to find a bed and sleep for at least an hour. This means your fallback options are reduced, forcing you to be more concerned about what you are walking into and whether you’re prepared to handle it. Some fights you may deem above your level and decide to avoid. Other fights you may decide to go all in. Scouting and gathering information to make this decision can be fun in its own right. Also, when beds are your only means of saving, they become the Holy Grail. With that level of importance tied to them, you will scour the Earth to find the closest bed to your next chosen encounter – and in doing so you will likely discover things that you might have otherwise missed.
No More Fast Travel: Fast Travel is disabled. If you wish to be somewhere, you’ll have to get there the old-fashioned way. In other words, exploration is now mandatory, exposing more of the Commonwealth’s secret gems. This will also take you out of your comfort zone, but encourage you to take advantage of the well-placed workshops throughout the Wasteland. And, while Charisma may seem less important to your immediate survival, there are certain Charisma-based perks that make managing your bases less painful.
Increased Lethality: You now deal, but also take, more damage. You can increase the damage you deal even further with “Adrenaline” – more on that in a moment. This makes combat more dangerous, which in turn slows you down and gets you to think about what you’re walking into. Combine this with it being much harder to save your game and suddenly each encounter becomes much more tense and dire.
If you’re playing Fallout 4, you can jump onto Steam and grab the Survival Mode Beta. You try it out and send them feedback to the Survival Mode Beta forum.
Fallout 4 is currently in beta for PC, and it will eventually be available for consoles. For more info on Fallout 4 Survival Mode click: Fallout 4 Survival Details
