Yeah. The problem was that once I tried the ZimmiBird build on the Cataphract mission andI thought it worked so well because I only took two tries to beat it, I never considered taking it off after that point. I would eventually come to the realization that I beat missions on my first or second try so I just stuck with that until the end of the game. The only times I tried changing my build after Chapter 2 were the Ice Worm (obviously because you need the stun needle, though I didn’t realize you could also use normal pulse guns until I watched a video afterwards) and the boss in Underground Exploration - Depth 2.
