Fallout games allow you to be as slow as you want with the right builds. It's never too fast tbh.

Are you explicitly looking for competitive multiplayer games? Single player shooters like Prey, or the BioShock games, might be able to fulfill what you're looking for. I like Helldivers 2, as well. It's not slow per se, but your fighting AI and not people so insane reflexes are far from important. It's coop but very worth your time.

The Far Cry games pretty much always allow a sniper and/or stealth option. Some of the scripted mission sequences can be fast paced, but it's largely open world. If you're not familiar with them, stick to the games with numbers in the titles for starters. Probably not 6. Maybe not 2 this day and age. 3-6 all exist with a particular style in mind.

Unless you're anti ubisoft

"Ready or Not" seems not to be recommended yet. It is basically a SWAT simulator you can play single player or together with 4 people.

You can choose your loadout freely to complete the missions. I recommend going blind into the missions on a first playthrough as some have some unexpected surprises ...

I highly recommend Void Bastards

Arma Reforger

Receiver 2, my dude.

An awesomely weird firearm simulation/stealth game, with a storyline consisting of equal parts gun safety, mental health awareness, and cult reprogramming. Almost every function of the player weapon is a different key on the keyboard. Reloading a single magazine is like a 4-6 keystroke sequence. A suddenly jammed weapon is like being presented with a tiny puzzle to solve, while under fire from deadly turret drones. One shot from an enemy kills you. You can and will shoot yourself in the leg. There is fall damage. There is broken glass damage. You are not an action hero, you are a sentient range target. Every bullet matters.

Anyways, it’s very paced, tense as fuck, and a decent challenge. The voice acting and soundtrack are also lovely.

If you can mind the obnoxious patriotic undertones, Hell Divers is actually my go to game rn. Partly hate it for the mentioned but overall, pretty decent game. I'm not a hard core gamer really (in general) but the game has grown on me and it's PvE so it's fun being able to play with others instead of being toxic.

if you wouldn't mind 3rd person stuff then I would recommend "conflict: " game series

Virtua cop

You have to reload "manually" 😁

Insurgency Sandstorm

Rainbow Six: Siege

People who play it like COD are the worst players in the game. Everything is designed to reward methodical, team-focused strategy so you can get the upper hand on people who don’t pay attention and try to rush everything.

I can highly recommend War Of Rights. Multiplayer only American civil war fps.

You form a long line in a field with 20 odd men facing the enemy line. It takes around 25 seconds to reload your gun, while the enemy is firing at you.

"Gentlemen, take aim, steady, steadyyy, steadyyyyyy, FIRE!"

The whole team gets penalised if you die out of line or duck for cover.

Generation Zero. Player power builds slowly, especially in single player.
