Bethesda has some changes lined up for Fallout 4. The game studio took to Twitter to announce the news, with the game's survival mode set for a "complete overhaul." As such, aspects like food, sleep, in-game diseases and threats will receive updates. Precisely what those changes are, have not been detailed yet, but it's said to be part of a major DLC that Bethesda is prepping along with a number of tweaks and fine tuning for the massive RPG title.

We’re also doing a complete overhaul of Fallout 4 Survival mode. Food, sleep, diseases, danger and more. Stay tuned.

For those unfamiliar with, or perhaps too scared to play, Fallout 4's survival mode, it is the most difficult mode in the game. It increases player's susceptibility to damage, as well as upping the health of enemies.

Polygon believes the changes will make Fallout 4's survival mode more in line with the one in Fallout: New Vegas, with features like permadeath and the inability to heal while sleeping. If Bethesda does indeed add that to this latest version of Fallout's survival mode, it will certainly up the ante.
