I played
Spec Ops The Line
Half Life Series
Call of Duty
Killzone

• DOOM 2016 and DOOM eternal for best atmosphere and shooting

• Bioshock series for best story

• maybe try Wolfenstein series altho I havent played it myself but a homie is a big fan

Titanfall 2 for sure

Wolfenstein is really good, also recommended

My suggestion is the Metro trilogy
Metro 2033
Metro Last Light
Metro Exodus

there's a remastered version for the first 2 games

Titanfall 2

^^^
Metro is great but it’s scary if you’re cool with that @op

Prey

Portal 1 + 2

Metroid prime trilogy if you can get a hold of it

Metroid Prime Trilogy

Dam

Real

Far cry 3 was dope but I wouldn’t recommend any of the other ones besides primal maybe

nothing topping half life im afraid

have u tried Black Mesa

Yep

Titanfall 2

Battlefield Bad Company
Prey 2017
Wolfenstein 1 + 2
Doom Eternal + Doom 3
Halo 1 to Reach
Metro series
Dishonered 1 + 2 (stealth based)
If youre on PC try Stalker series, the upcoming sequel will come out in a year or two for consoles as well
Bioshock 1 & Infinite (2 is ass imo but you can try it as well, its 50/50 in the fandom)
Deus Ex Human Revolution & Deus Ex 2000
FEAR 1 (the other 2 are garbage almost no one likes them, but the og is classic)
Oddworld Strangers Wrath
Fallout 3, New Vegas & 4 (RPG based)
Condemned Criminal Origins (horror & detective based FPS)
The Darkness

Resistance is a better Sony shooter series than Killzone but I wouldnt say either are amazing

@op

Metro, Stalker, Dishonered, Bioshock & Deus Ex are the best series' imo.

Half Life 1 n 2 arent that impressive to me anymore especially part 1. Still good tho n of course revolutionary for its time.

But I guess im more of a fan of the "thinking mans" shooter than the straight up ones, boomer or mainly cinematic ones.

MW2

Portal 1-2
Bioshock and Bioshock Infinite

Titanfall 2 has one of the best FPS campaigns of last-gen, has a very Valve feel to it.

Portal 2 is a really good one, also Prey.
