The 10 Best Co-Op Games on Steam to Enjoy With Friends

Some nights, playing games alone just doesn't cut it. We long for the chaos, the laughter, and the “did we really just pull that off?” moments, and they only happen when friends pile into the same match. That's where co-op shines, and we can't deny its success in this era. If you're looking for a game to make your night an unforgettable story, we present you with our ranking of the top ten co-op games on Steam right now.

Best Co-Op Games on Steam at a Glance

1. Helldivers 2: The Best Squad Shooter on Steam

Four players, one dropship, and the excitement of every reload that feels like you're in jeopardy - in a nutshell, that's Helldivers 2. It's a third-person shooter where you and your friends spread “managed democracy” throughout the galaxy, equipped with stratagems capable of killing off even your own teammates. This, together with the live Galactic War that shifts the map every week, adds another layer of chaos to an already chaotic backdrop of a game. In September 2025, game users peaked at 182,000, and hovered past 170,000 when the Cyborgs arrived. Nothing else on Steam captures that full-squad panic quite like this game.

2. Baldur's Gate 3

If you're not clingy like that, Baldur's Gate 3 might be for you. It's also a four-player game, and unlike action RPGs like Diablo, each player can run their own character, split up, and interact with different quests at their own pace. Fast reflexes are not necessary, since combat is done in turns, and outside of that, it's making choices and building a story in a reactive world. It's honestly the best RPG game there is. With Patch 8 adding full crossplay that allows PC, PlayStation, and Xbox players to play together, you can now loop everyone in the same lobby regardless of where they're playing from.

3. It Takes Two and Split Fiction: The Best Games for Two Players

Hazelight's forte is making co-op games meant only for two players. After It Takes Two sold over 30 million copies and won the Game of the Year award in 2021, they followed up with Split Fiction in 2025. The latter is a clever fusion of sci-fi and fantasy. Both games retain the Hazelight trademark, like the split screen setup and Friend's Pass system, which only needs one player to purchase the game. These features make it hassle-free to collaborate and organize a two-player night.

4. Deep Rock Galactic

“Rock and Stone!” is the cry that every Deep Rock Galactic player knows, and it perfectly sums up the vibe of this game. The setup is that there are up to four space-mining dwarves dropped into caves, each of you assigned a class, and then you try to dig your way out before the swarm eats you alive. You really need to have teamwork here: that's an important part of the game design. The Scout lights the cavern, the Engineer builds the platforms - each has a role to play. It's a complete and polished game that gets regularly updated, and its quick mission mechanism allows you to play at random hours without needing to log in at the same time.

5. Lethal Company: Co-Op Horror With Proximity Voice Chat

One of the standout new co-op hits of recent years, Lethal Company is proof that sometimes the scariest part of a horror game isn't the monster, but hearing your friend scream on voice chat and their voice fading away til it gets silent. In this scavenging game, four players will land on abandoned moons where your only mission is to collect enough scraps to hit a company quota. You will also need to decide who carries what, who risks going deeper, and who opens the next door. Here, every run feels unpredictable, and every disaster is always someone's fault.

6. Monster Hunter Wilds: The Best Co-Op Hunt

Monster Hunter Wilds is a 4 player action RPG built around high-intensity group fights. Your group will go around with enormous weapons, hunting monsters, and yelling over voice chat. The gameplay loop has you teaming up to bring down a monster, craft gear from its parts, and then raid something even bigger. Chaos reigns supreme here, making it perfect for nights when all you want to do is jump straight into the action without too much setup to fall back on.

7. Valheim

Valheim stands out in co-op gaming as one of those games built for big teams. It's a rare crafting game that supports up to ten players. You join the same world, chop trees, raise longhouses, sail across dangerous seas, and take down massive bosses. The best part is that this game is still growing, with the long-awaited Deep North DLC coming in September 2026.

8. Stardew Valley: The Cozy Co-Op Farm for Eight

Co‑op nights don't always have to involve monster killing or racking up a body count. Sometimes, what you really need is a cozy and chill farming game like Stardew Valley. Since the 1.6 update landed, it has increased the cap from four to eight players, making it the perfect farming multiplayer game. You and your friends can spread out all over Pelican Town, where one of you might be fishing by the river, another mining deep in the caves, or tending animals. This is also the type of game you keep open in the background while the group talks about everything except the game. This is perfect for stress-free co-op nights with friends to escape the fast-paced life.

9. Risk of Rain 2

Risk of Rain 2 is all about chaos but in the best way. It's a roguelike whose core progression mechanic sends four players on fast‑paced runs as the difficulty ramps up over time. In this game, every minute is important as items stack endlessly. By the 30‑minute mark, you're going to have one of your friends look like a walking firework, and your screens filled with explosions and lasers. With the release of the Seekers of the Storm pack, there are new features to explore and more chaos for players.

10. Left 4 Dead 2

Some games fade, but Left 4 Dead 2 is the one that never leaves any co-op gamer's library. It is the game that set the standard for co-op FPS games. With four survivors and endless waves of zombies, every playthrough will feel different, and every escape will feel miraculous. This sequel has the full package with more campaigns and weapons while being cheap and populated. When your squad can't agree on what to play, Left 4 Dead 2 is the automatic go-to; alternatively, your squad can try out similar zombie shooters like Back 4 Blood or Zombie Army 4.
