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.
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, within reason.
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.)
Rest assured that you were nearly done.
I'm kidding, but it do believe it's only 6 hours or something. Still amazing.
