First try boss beatdown

I "recorded" this long before I was a youtuber (back in 2021) to show to some friends, so now I'm showing it to you all.
A bit about this video: I was only able to beat this boss first try because of my loadout. If I didn't have the healing vials or the gun I had (and everything else that I don't remember), I wouldn't have been able to beat this boss first try.
Also, side note: The Electropylon Driver the BEST gun in the game (In my opinion).
