I Somehow Managed This. JETSTREAM SAM IMPROVED 5.0

As it turns out, someone decided that MGR bosses weren't hard enough, and made a mod pack to improve their durability and speed, along with making them immune to perfect parries, or even blocking. So naturally, I downloaded the mod, made by Sp00ky, or Sp00ky480. The mod is on Nexusmods. If you are reading this, then I thank you for bringing this mod to life and allowing me and others to experience the game with a new set of challanges and improving what are already great bosses. Here's a link to their mod if you wish to check it out: https://www.nexusmods.com/metalgearrisingrevengeance/mods/327?tab=description
