And its more than just adding the need to eat, drink, and sleep to the game. With fundamental changes made across the board, like not being able to save your game unless you sleep, and disabling fast travel all together, Survival Mode is shaping up to be a pretty unforgiving and challenging way to play Fallout 4. Available now on Steam as Survival Mode Beta, Bethesda is actively looking for feedback from players to help shape it into quite possibly the most interesting way to play Fallout 4 yet.
So yeah, its going to be intense.
In terms of combat, with both player damage and enemy damage getting a huge buff, comparisons to something like Dark Souls isn't lost on the developer. The focus of this revamped Survival Mode is to add a layer of strategy to each enemy encounter, put an emphasis on resource management, and putting players in the role of someone exploring a dangerous Wasteland. Without being able to save unless you sleep, or fast travel, and with the overall carry weight getting a decrease alongside bullets and Stimpaks and other items getting individual weight values, what to carry and how far to venture out into the Wasteland will be given new meaning. Not to mention the fact that Settlement expansion will play a huge role in strategically exploring the world and being able to scavenge, craft, build, and cook.
There's a lot to take in with this update, a new Adrenaline system is introduced where the damage you deal increases substantially the more you engage in battle. With adrenaline depleting as soon as you sleep. Or only slightly if you take a nap. Then there's the new illness system where your character's immunity depletes when taking radiation or other chems, leaving you susceptible to disease. Also, depending on what you drink or eat, it may adversely affect something like thirst or fatigue or immunity.
Wellness – Exhaustion, Hunger, Thirst: You'll find it difficult to survive without taking proper care of yourself. You must stay hydrated, fed and rested to remain combat-ready. Going for extended periods of time without food, water or a good night's sleep will begin to adversely affect your health, hurting your S.P.E.C.I.A.L. stats, adding to your Fatigue, lowering your immunity, and eventually even causing physical damage to you. This will affect every decision you make, because you have to consider your overall and ever-changing health. The drive to simply stay alive might push you into new and unexpected adventures. At the very least, you’ll likely find yourself hunting for valuable meats, triggering encounters with dangerous wildlife. But not everything you can consume is good for you: Certain items in the game now have negative consequences to balance out their positive effects. These counter-effects may make you thirsty, hungry or tired and possibly even hurt your immunity, leaving you vulnerable to Illness.
It all sounds intense to say the least, and pretty amazing too. The level of detail in this update probably exceeds even our wildest imagination. The fact that if you attempt to travel huge distances whilst being over-encumbered you'll probably break your legs or back, points to this fact. As does the significantly slower rate of enemy and loot re-population. And the type of bed affecting the quality and duration of sleep.
Bed Types: The type of bed you're sleeping in limits the length of time you are able to sleep, thereby limiting how much you can recover. Real beds – which are hard to come by in the world – offer the highest bonuses for sleeping; this rewards you for working out of a home base or even spending the caps for a good night’s sleep. Also, finding a sleeping bag in the middle of a dungeon will feel great… finding a dirty mattress will feel even better… finding a real bed will be like winning the lottery. You know all those spots where you can use Workshop mode in the game? It’s time to start building beds.
