The 20 Best-Rated Cooperative Games On Steam Right Now

20. Crab Champions (2023) – 8.58

Some games take themselves too seriously, but Crab Champions is gleefully absurd in the best way possible. You take control of a gun-wielding crab, darting across tropical islands, chaining wild combos, and stacking ridiculous power-ups that turn you into a crustacean powerhouse. The action is fast, chaotic, and endlessly replayable, with roguelike elements that keep every run feeling fresh. Teaming up with friends only amplifies the madness, as every explosive encounter becomes an excuse to shout, laugh, and accidentally fall off cliffs together. It’s over-the-top fun with just the right amount of self-awareness, proving that sometimes the weirdest ideas make the best games. And really, who hasn’t dreamed of being a crab with a rocket launcher at some point? | © Noisestorm

19. Brotato (2023) – 8.58

You wouldn’t think a potato could star in one of the most frantic rogue lite shooters on Steam, but here we are. Brotato drops you into waves of enemies, letting you stack an arsenal of weapons while your spud auto-fires at anything in sight. The real magic lies in the builds – you can create wildly different runs, from a potato sniper to a potato flamethrower juggernaut, and everything in between. The pacing is rapid, the choices meaningful, and the chaos downright addictive. Co-op runs let you and your friends debate which mutant potato looks the silliest while shredding waves of baddies. It’s goofy, stylish, and surprisingly deep for a game about a vegetable. If you ever doubted potatoes could be heroes, this little tuber will set you straight. | © Blobfish

18. Rhythm Doctor (2021) – 8.60

Very few rhythm games manage to teach complex music theory without ever feeling like homework, but Rhythm Doctor pulls it off brilliantly. With a single button, you’re tasked with saving patients by hitting the seventh beat – easy at first, until the game starts throwing syncopation, polyrhythms, and visual trickery your way. It’s clever, frustrating, and rewarding all at once, with level design that keeps you on your toes. In co-op, the tension doubles as you and your partner must keep rhythm under pressure, laughing at every missed beat or glorious save. The art style is charming, the soundtrack infectious, and the whole thing feels fresh with every play. This is rhythm gaming at its smartest and quirkiest, showing that great design can turn music into medicine. | © 7th Beat Games

17. Cuphead (2017) – 8.61

It looks like a 1930s cartoon, but Cuphead plays like a devilish gauntlet of boss fights designed to test every ounce of your reflexes. Studio MDHR painstakingly hand-animated every frame, crafting visuals so gorgeous you almost forget how many times you’ve died. Almost. With a friend by your side, the challenge transforms into a rollercoaster of tension and relief – one moment you’re screaming at missed jumps, the next you’re howling in triumph. The jazz-infused soundtrack pumps the adrenaline, while each boss encounter feels like a bizarre fever dream brought to life. There’s nothing quite like the moment when you and your co-op partner finally sync up and beat that impossible fight. It’s punishing, yes, but it’s also pure joy once victory lands. | © Studio MDHR

16. BattleBlock Theater (2013) – 8.61

Platformers don’t usually come with a side of snarky narration, but BattleBlock Theater thrives on its bizarre humor. The Behemoth created a world where betrayed friends, sock-headed prisoners, and deadly stage traps collide into chaotic co-op comedy. Every level is designed to trip you up and test your teamwork, often leading to hilarious accidents instead of clean victories. That unpredictability is what makes it shine – you’re never sure if your partner will save you or accidentally doom you. The gem-collecting, puzzle-solving, and slapstick action blend into something that feels equal parts game and comedy routine. Add in a narrator who seems as amused by your suffering as you are, and you’ve got an unforgettable co-op ride. It’s ridiculous, but that’s the whole point. | © The Behemoth

15. R.E.P.O. (2025) – 8.61

Horror and object retrieval don’t sound like a natural pairing, but R.E.P.O. makes it work in the most chaotic way possible. Semiwork throws you and up to five other players into eerie locations where your job is to collect artifacts – simple enough, until physics, panic, and lurking horrors join the party. One wrong move and that priceless object goes tumbling, triggering a cascade of screaming and scrambling. The tension comes not only from what’s chasing you, but from the hilarious unpredictability of handling fragile items under pressure. Co-op play ensures no two runs are the same, with every group of friends finding new ways to mess up spectacularly. Equal parts spooky and slapstick, this is survival horror with a quirky, unforgettable twist. | © Semiwork

14. A Hat in Time (2017) – 8.63

Whimsy is alive and well in A Hat in Time, a love letter to classic 3D platformers. You play as Hat Kid, a tiny alien adventurer with a big hat and an even bigger sense of charm. Each world bursts with color, personality, and clever platforming challenges, offering the kind of variety that keeps exploration endlessly fun. From Mafia Town to spooky forests, every chapter feels like its own little cartoon episode, filled with quirky characters and memorable bosses. Co-op mode makes it even better, letting two players explore together in a joyful, light-hearted romp. The hat powers are fun to collect and even more fun to use, keeping the gameplay fresh all the way through. It’s heartwarming, playful, and packed with character. | © Gears for Breakfast

13. Split Fiction (2025) – 8.63

Hazelight Studios loves co-op adventures, and Split Fiction pushes that reputation even further. You and a partner play as authors trapped in your own stories, jumping between fantasy quests and sci-fi showdowns with mechanics that change every chapter. One moment you’re slaying dragons, the next you’re puzzling through laser-filled mazes – it’s unpredictable, inventive, and consistently surprising. The writing leans into humor and emotion, making the adventure feel like you’re starring in your own buddy movie. Co-op is essential, as each challenge requires real collaboration, not just parallel play. It’s a narrative rollercoaster, blending heartfelt storytelling with inventive gameplay twists. Few games make teamwork feel this rewarding, and that’s Hazelight’s special magic. | © Electronic Arts

12. Phasmophobia (2020) – 8.65

Few co-op games capture fear and laughter as perfectly as Phasmophobia. Armed with ghost-hunting gadgets, you and your friends investigate haunted houses, schools, and asylums where every creak in the dark could be something sinister. The tension builds as you gather evidence, call out ghost names, and watch your sanity slowly tick down. But it’s the unpredictable scares – doors slamming, lights flickering, or a sudden apparition – that keep you on edge. Co-op chaos is the heart of it, as players scream, split up, or botch strategies in hilarious ways. The thrill comes from balancing real dread with playful teamwork, making each hunt memorable. It’s spooky fun you’ll want to revisit again and again, even if your nerves tell you otherwise. | © Kinetic Games

11. WEBFISHING (2024) – 8.65

Fishing has never been this weirdly social – or this funny. WEBFISHING takes a cozy fishing sim and flips it into a multiplayer hangout full of giant fish, customizable avatars, and surreal sandbox toys. Instead of grinding for gear, the joy comes from chatting with strangers, showing off bizarre catches, and occasionally rocking out with virtual instruments. It’s less about the fish and more about the vibes, creating a space that feels as much like a virtual campfire as a game. Every catch is a conversation starter, every avatar a little piece of comedy, and every fishing trip a chance to make new stories. Perfect for chill evenings when you want lighthearted fun with friends. It’s strange, endearing, and undeniably unique. | © lamedeveloper

10. Factorio (2020) – 8.67

There’s something strangely satisfying about building a sprawling machine that eventually runs itself, and Factorio embodies that satisfaction perfectly. This engineering-focused co-op sim starts small – mining some ore, building a furnace – but before long, you’re designing intricate conveyor belts, automated factories, and entire supply chains. With friends, the complexity scales hilariously: someone’s always in charge of “fixing” the spaghetti mess of conveyors while another experiments with nuclear power. The beauty is how every problem feels solvable with just one more clever design, leading to hours that disappear in the blink of an eye. It’s addictive, it’s brainy, and it’s cooperative problem-solving at its finest. Whether you love tinkering or just want to automate everything in sight, this is a masterpiece of design. | © Wube Software

9. Satisfactory (2020) – 8.69

If Factorio is a love letter to 2D logistics, Satisfactory is its towering 3D cousin – factory building with a view. Coffee Stain Studios throws you and your friends onto an alien planet where every mountain, cave, and open plain is an opportunity to build sprawling industrial marvels. Conveyors snake across valleys, sky bridges tower into the clouds, and giant machines roar to life under your watchful eye. Co-op transforms the experience into pure collaborative chaos: one friend optimizes layouts, another builds “aesthetic” pipelines that somehow take hours, while someone else just drives a tractor into the ocean. It’s equal parts serious planning and playful freedom, giving you a sandbox where efficiency and creativity go hand in hand. | © Coffee Stain Studios

8. Deep Rock Galactic (2020) – 8.72

Dwarves, pickaxes, and giant alien bugs – what could possibly go wrong? Deep Rock Galactic drops you and up to three friends into procedurally generated caves to mine resources and blast hostile swarms. Ghost Ship Games makes sure the action never feels routine, with objectives ranging from mining rare gems to repairing machinery, all while managing dwindling ammo and unexpected ambushes. Teamwork is everything: scouts zip around lighting caverns, engineers build platforms, gunners mow down hordes, and driller players… well, drill. Missions turn into wild stories of near-death escapes, last-second rescues, and triumphant shouts of “Rock and Stone!” It’s chaotic, hilarious, and endlessly replayable, a shining example of co-op done right. | © Ghost Ship Games

7. Bloons TD 6 (2018) – 8.72

At first glance, balloon-popping monkeys sound like child’s play– but Bloons TD 6 has earned its spot as one of the most beloved co-op tower defense games on Steam. Ninja Kiwi took the already addictive formula of placing towers and upgrading them against waves of balloons, then added depth, strategy, and endless replayability. In co-op, each player brings their own flavor of chaos, pooling cash and arguing over who gets to drop that overpowered super monkey first. The charm lies in its simplicity mixed with surprising complexity – every run feels different, every victory oddly triumphant. It’s colorful, it’s challenging, and it’s far more intense than you’d expect from a game about balloons. | © Ninja Kiwi

6. The Binding of Isaac: Rebirth (2014) – 8.72

Few games balance grotesque themes with such compelling gameplay as The Binding of Isaac: Rebirth. Edmund McMillen and Nicalis created a roguelike dungeon crawler where every run brings new rooms, bizarre enemies, and wild item synergies that transform your character in unpredictable ways. Co-op lets a friend jump in as a baby companion, turning the lonely chaos into shared survival. The game’s dark humor and shocking imagery contrast with its addicting design, making it a cult classic that refuses to loosen its grip. You’ll die, restart, and die again – but every run feels fresh, daring you to push just a little further. For those who like their co-op gaming with a heavy dose of weird, Isaac delivers. | © Nicalis

5. Lethal Company (2023) – 8.73

Indie surprise hit Lethal Company proves that sometimes, simple ideas make the best co-op experiences. As part of a ragtag salvage crew, you and your friends explore abandoned industrial complexes filled with traps, monsters, and valuable scrap to haul back to your ship. The catch? Every outing is a tense balance of greed and survival – stay too long, and the horrors lurking in the dark will happily punish your ambition. The emergent chaos of multiplayer is the real hook, as teammates panic, scream, and betray each other (usually by accident… or so they claim). It’s spooky, silly, and dangerously addictive, offering the perfect mix of tension and laughter. | © Zeekerss

4. Schedule I (2025) – 8.77

Hold the phone – this indie game isn’t about class scheduling; it's building a neon‑light drug empire with all the dark comedy you didn’t realize you needed. Solo developer Tyler’s Video Game Studio (TVGS) dropped Schedule I into Early Access in March 2025, letting you and up to three pals manufacture, mix, and distribute cartoon narcotics in the gritty streets of Hyland Point. Its rise was meteoric – hitting top seller and peaking at hundreds of thousands of concurrent players within 24 hours. You’ll cultivate, concoct absurd minigames, and dodge cops, with every run a beaming mix of strategic planning and spontaneous mayhem. It’s bold, edgy, and undeniably standout – a tycoon-style drug sim that somehow earns its laughs. | © Tyler’s Video Game Studio (TVGS)

3. Left 4 Dead 2 (2009) – 8.80

Few co-op games have achieved legendary status quite like Left 4 Dead 2. Valve’s zombie shooter is fast, brutal, and endlessly replayable, with campaigns that throw you and your friends into desperate battles against overwhelming undead hordes. What makes it shine is the unpredictability – the AI director changes spawn patterns, difficulty, and item placement each time, keeping you on edge even if you’ve played a map a hundred times. The special infected add an extra layer of chaos, forcing teams to stay tight-knit or risk being dragged into the dark alone. Even years after release, it remains one of the defining co-op shooters on Steam, still played and still loved. | © Valve

2. Terraria (2011) – 8.82

It may look like a pixel-art sandbox, but Terraria is one of the deepest and most rewarding co-op adventures out there. Starting with nothing but a pickaxe and a dream, you and your friends can shape the world – digging, building, crafting, and battling your way through increasingly powerful bosses. The beauty of Terraria lies in its freedom: some players build elaborate castles, others dig endless tunnels, and some just chase loot drops and epic fights. The sense of discovery is unmatched, with secrets, biomes, and magical weapons hidden everywhere. Co-op elevates the experience, turning it into a shared epic that can last hundreds of hours. It’s Minecraft’s weirder, combat-heavy cousin – and it’s glorious. | © Re-Logic

1. Portal 2 (2011) – 8.85

At the top of the list sits Portal 2, Valve’s puzzle masterpiece and one of the finest co-op games ever made. The single-player campaign is iconic, but it’s the dedicated two-player co-op mode that truly shines, forcing you and a partner to think in four dimensions. Every puzzle requires communication, coordination, and often a fair amount of trial and error – but the “aha!” moments are unmatched. The humor is sharp, the writing brilliant, and the mechanics endlessly inventive. It’s the rare co-op game that feels perfectly balanced for two players, where teamwork isn’t optional but essential. A decade later, it’s still the gold standard for clever, cooperative design. | © Valve
