Starship Troopers: Extermination is PvE wave/extraction shooter, from the company that developed Squad. Looks pretty fun but if you are not into that universe nor have enough friends you’d need to rely on other players as well.( basically max 12 players in 3 teams atm.) Warning: early access so if you are not tolerant to EA type of development/update cycle just avoid.

There is a couple other PvE wave/extraction shooter as well, so give them a try.( Just google that term, usually around $30 and could go on sale.)

Rocket League, this one I played since launch and really good game to start before your group all come online and then move on to other games.(since it supports up to 4v4, but usually people only queue 2v2 or 3v3 matches.)

Unrailed is a good one https://store.steampowered.com/app/1016920/Unrailed/

Squad! super fun game to play with friends. It’s an FPS that isn’t as hard to learn as Arma and more milsim than an arcade shooter like battlefield.

My husband and I have easily gotten hundreds, maybe thousands of hours out of each of the Gears of War games. I would recommend the first three absolutely.

While I find the campaign OK, I love the Horde mode in the games.

Me and my wife have been really enjoying Bread and Fred. Your two penguins tied together who have to use your momentum to climb a mountain. It’s in the genre of “getting over it” where you can fall at any time and lose all progress. Two player only, it’s more a couple game.

I don’t see overwatch 2 on the list. I think the game gets an unfair amount of hate, it’s one of my favourite games. One of the few games that is competitive but not Grey army colours. Community is toxic, and it takes a long time to learn though. It can be an exceeding satisfying game, but unfortunately I think it only really gets fun at Plat and higher elos (similar to csgo in that regard)

Stardew valley is a great vibe game that I don’t see listed. One if the best games for casual chat and play imo.

Vermintide and Vermintide 2 are great games in my opinion that expand and innovate on the L4D2 formula, being similar but still very distinct.

Overcooked, Overcooked 2, Movin Out, Out of Space, Cod Zombies, PlateUp!

If you enjoyed risk of rain 2 I would recommend the binding of Isaac which is another roguelike

Barotrauma! I even set up a lemmy community for it.

World War Z Aftermath is a great multiplayer game and also cross-platform!

Try Factorio!! It’s got a demo you can try to get a taste as well. I spent ~20 hours in the demo itself before I bought the game. Looooved it.

If you like horror Outlast Trials is pretty good. It’s a little short on content (there are 9 unique missions) but the experience is well worth the money, I’m hoping they add new content soon.

Outlast Trials is the big coop fun surprise of the year for me. You can also still buy it 25% off on epic for like 20€ until today.

People should not ignore this game cause it is from the outlast series. This game has way less jumpscares and its more about the tension of being chased all the time. Also way less scary in coop than in solo. It’s more like Deadbydaylight meets L4D2 mobs. Level and Character Design reminds me off Bioshock. The coop fun is comparable to Phasmophobia, just less scary but more tense

Golf with Friends is casual and at times frustrating fun. Don’t have to wait for each person to hit the ball before you hit yours either, so the games courses don’t drag on.

I’ve had a lot of fun playing Grounded. Both with friends and solo. Someone needs to host the session but it is a shared save file that keeps up to date very well. So, any individual can play at any time or up to 4 can play online together.
