Two months ago I did this pacifist run of episode 1. I had been attempting this for a few months before this. Has something like this been done before? Anyway I just thought some people would find it interesting.

I think the pumpkin man decino made a video about that

He did a video about playing every level shotgun starting

This is not a pacifist run, since you directly kill Chthon at the end, evidenced by the killcounter going up by 1. Since most levels, apart from e1m7 and e2m6 are trivial to complete pacifist, nobody bothered.
