Which doesn't make sense because survival mode is bringing in new things like antidotes and other things which would need to have a use in the other difficulty modes. That's why i'm saying it sounds more like a MODE than a difficulty setting, which hardcoe mode was.

And what do you need antibiotics for in the other difficulties since it used for deceases which are added by the new survival?

You're missing my point, those are actual new content in the game. The only time those items are exclusive is if it's a new mode and not a difficulty setting. The difficulty setting only changes how damages or health affect the player or enemies. It doesn't just keep items exclusive unless it's selected although i'd be impressed if they could do that knowing how shotty bethesda can be with their development on games.

My point is : when will this be implemented?
