Enemy difficulty scaling in Fallout 4
Does enemies difficulty scale as you level up?
This seems like it would mean I should invest in combat perks in the early portion of the game?
Yes they do scale but this seems to only impact areas you've not visited before.
How did I test? Increased my level to 200 and stomped on all of the level 10 enemies for a bit, then moved to a new area I hadn't been to before, encountered a level 201 legendary and ran out of ammo before I could take him down.
