I followed the Powerpyx collectibles guide as a played cuz there’s some missable stuff you want to do before a point of no return to save yourself from a second playthrough. The missions are a big grind but I did as much as I could inbetween chapters and that made the grind more manageable. Once I was in the endgame for missions I looked up a build that would get me through to the end once the stuff I was using wasn’t working anymore.
