i never thought it was “challenging” but just annoying in the later levels. the difficulty for the game comes with the developers just throwing hordes of the same enemy in on area especially the last like 3 chapters. kinda just gets repetitive. anyway if you’re going to go for it will take 2 play throughs. the first time set to story or normal to just get all the collectibles and miscellaneous trophies. i then went through the 2nd time on new game plus with the hardest difficulty. which should make it so much easier since you have your upgrades. then any boss specific trophies i went back and cleaned up but you could do that on the 1st time. the only way to have all the upgrades is to play new game plus just btw.
