it's me again so sorry to keep writing dumb questions, but i have an issue with the tyrant fight that rebecca takes part in. i've had a look at all of your speedruns and you guys just hold down fire and he dies without inflicting damage, for me, he keeps swiping at me. is this fight random? i am playing on normal mode

DON'T hold down fire at the begining, you have to wait a bit (I'm using a setup with the music), after count yours 8 bullets, and then mash the reload button, and that should be good.
