Oh hell yes.

I'm playing Horizon Zero Dawn Complete (it includes the DLC) and as soon as I got to Daytower, I ran into a guy named Ohtur who mentioned The Cut.. I pivoted and headed up there and by sneaking around everything with higher stats than I had, (which was almost everything) I managed to find resources that got me a wickedly powerful weapon. Game changer. Literally.

Getting to any part of the map and find it's hidden goodies is amazing.
