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 Bungie era of Halo (Combat Evolved through Reach). You can never go wrong with those games, and the soundtrack alone will get you pumped to play through humanity's last stand.
Only looking at FPS games, specifically only shooters here. Note this is leaving out other first person games that I play on occasion such as Morrowind and Arx Fatalis.
Someone else mentioned it. I have never played Bioshock, I think I've seen it used as a benchmark. I look for military style games and I wasn't sure if I should give Bioshock a try.
Bioshock is a fantastic game imo if you're willing to branch out from military games. The story is wonderful, the setting is phenomenal and the shooting mechanics are very solid and fun. You can probably find the remaster for cheap, it's often on sale.
You should really give the Wolfenstein games a try if you already own them.
After about an hour or two you will know if the game is for you. Start with New Order.
There is no melee weapon in Prey, except the wrench you start with. It is a Sci-Fi game, set on a space station. The focus is on finding your own solutions to problems by using different skills you unlock. Strength, hacking, stealth and so on. It is an immersive sim, but you can play it like a shooter too. It demands some attention though, or you will not know what to do next.
Turbo Overkill has multiple levels you complete one after another. It is a classic FPS game with a campaign. The big fights happen in large arenas though. The game is very fast and you have to use a lot of different movement abilities to survive on harder difficulties.
I've been meaning to try the original Crysis now that I have a computer that can play it. I started it, but then life happened.
DOOM Eternal didn't do it for me. It's Doom-ish, but not enough. It'd be a better game if it wasn't set in the Doom universe trying to add a bunch of non-Doom elements to the game. Doom (2016) did that too, but not to the same extent. I like the older Dooms mostly for their simplicity: get gun, see bad guy, shoot gun. Pick up health. Repeat. Doom Eternal did that, but added a story, weapon mods, and skills. Fine mechanics, but not Doom enough for me.
DOOM Eternal was like a ... crazy adrenaline pumping high for me that I normally don't get out of single player games, so that's why it's arguably my favorite.
I never really played the original DOOM games (they're almost too simple for me ... I didn't grow up with them but I did get into PC shooters with Xonotic -- a fast paced Quake derivative, so DOOM Eternal kinda makes sense for me).
DOOM Eternal is pretty damn close to perfection. The only thing that keeps it from 10/10 for me is the length of the missions, especially on harder difficulties. I feel absolutely exhausted after just one level.
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.
