Hello everyone,

Thanks to reddit user NASCAR_Junk_YT who got me curious, I tried repeating what he was describing on one of my latest save.

The goal is to flash her as she's transitioning into her next phase (when she turns grey). Repeat the process until you reach berserk phase, where I couldn't get it to work. The user said it worked for her "3rd stage", but I'm not sure if he's mentioning her last berserk phase. This is on the PC version.

Same save, this time with Infinite Ammos :

After searching on youtube, user Shiny Gamey had a clue as he saw the bug on a youtube Livestream (MauLer). Another youtube user E-Lazzer got her to get stuck while charging on her spider form.
