I've been searching in Data0.pak (In atom). I would like to disable the restriction of using deveolper weapons in nightmare mode. I can't find in the Data0.pak anything regarding the developer weapons being restricted to the Nightemare difficulity, but it is. Any one can help me? Where can I change that? I already modded a bit of the Data0 and I beleive that's what left for me, I can't see it. TL;DR: Where can I change that in nightmare difficulity I will be able to use developer weapons? Also, is it possible to mod both me and a partner's dying light game that we could trade DRoPs? Thanks, doom.
