I envy people who can make mods. There are YouTube tutorials on making Resident Evil 3 Remake mods, and I assume that the same method could be used for this game. While it's something that I'd like to try when I have time, there's more that I'd like to alter besides the appearance of the protagonist, which I haven't found a tutorial for. It must've taken a lot of work to get a character to act differently, or to get different camera views.
I found this mod. After completing the game in first person, I think trying this one would make it a new experience.
