What are people's recommendation for their favourite FPS single player campaigns that you still enjoy playing a couple of levels once in awhile? No multiplayer suggestions.
My all time one is Medal Of Honor 2010 reboot. I don't play through it every time but I have a couple of favourite levels.
The online favourite in Zandronum (multiplayer ZDoom) was Alien Vendetta, an awesome Doom2 campaign WAD. (av.wad or av20.wad) It's just super solid with lots of variety and good pacing. Made by a bunch of different mappers.
No game suggestions, friend requests, surveys, or begging.
No Let's Plays, streams, highlight reels/montages, random videos or shorts.
No off-topic posts/comments.
Use the original source, no clickbait titles, no duplicates.
(Submissions should be from the original source if possible, unless from paywalled or non-english sources.
If the title is clickbait or lacks context you may lightly edit the title.)
GZdoom, Brutal Doom, FreeDoom (all packaged for the basis of a single game) then... something to pick there and play: https://www.doomworld.com/10years/bestwads/
