The bosses in metroid prime2 on GameCube. If you thought dark souls' bosses could be tough, you're in for a whole different world of pain in prime2 Note that in metroid prime trilogy collection for wiiU, you now have a choice of difficulty which wasn't available before. So hard mode was originally the standard default difficulty Also, who remembers Jet Force Gemini on n64?The bosses could be a pain, and I never did defeat mizar at the end - that battle was beyond a joke!
