Resident Evil 4 Remake | Professional S+ | No glitches, No extra items, No infinite ammo

So... with past REs I've made the mistake of watching speedruns before going for this type of runs. That's fine, but it takes away the pleasure (or suffering, depending on who you ask) of smashing your head against the wall until you break it, aka figuring out the way to beat a certain part.
This is the most fun I have in videogames: setting a challenge for myself, and trying to beat it with basically no help.
This is what happens when I throw myself at a game, without planning anything in advance, on its hardest difficulty, with the added challenge of wanting to get that sweet S+ Rank in the very same, first ever, Professional run. Scuffed will be said multiple times in this video! lol
