Simple mod that edits the damage multipliers of survival mode to match that of hard difficulty. So the player deals 0.75x damage (so no change there) and the enemy deals 1.5x damage (as opposed to 4x). I decided to make this mod as I really enjoyed survival mode but found the enemy damage a bit OP and frustrating.
UPDATE 3: Added changes in a new custom hidden perk, as merely editing the original meant that changes wouldn’t take effect unless survival mode was restarted. So now the incoming damage changes take effect even if you are in the middle of a survival mode playthrough.
