At first I thought it was taken from Cyberpunk 2077, but now I'm not too sure.
I swear I've seen near identical animations somewhere, but it could just be coincidence. There's only so many ways you can draw a revolver shooting, I guess.
You know of all the retro-fetish shit to come out in recent years I wish there would be more LucasArts/Sierra style Point and Click games. That's a lost artform and from what I've seen the people who have the most nostalgia for it are aging Xers, not Troons. I mean there's been a few here and there, but it seems like all anyone gives a fuck about is doom clones, Metroidvanias and PS1 graphic troonprojects.
