Best Co-Op Games On Steam To Play Right Now

Steam has every type of project imaginable, and co-op games are hardly an exception. Be it action, open-world, horror, or survival, friends can join forces to play through a campaign together, which can make for a wildly different experience from the single-player version. Heck, a few of Steam’s best co-op games, like Split Fiction, do not support solo runs at all, so you will need to find a partner to enjoy them.

There are roughly a billion games on Steam, and sifting through this endless catalog can be tiring, frustrating, and just confusing. Which games are actually worth playing? What title should you play with your spouse, child, sibling, or friend? We are going to simplify the process by highlighting a few of the greatest co-op experiences on Valve’s platform. This isn’t an exhaustive list by any stretch of the imagination, but it should be enough to get people started.

Updated April 19, 2026 by Mark Sammut: Two more co-op games have been added to the article: Toxic Commando and TMNT Splintered Fate. The former is a relatively recent release, while the latter is a game I am playing in co-op right now.

Quick Picks: Best Co-Op Steam Games To Play Right Now

While we will explore games individually, let’s first put together recommendations for a range of needs and circumstances. Basically, if you are just looking for a quick rec, the following table should help get you started. I’ll try to cover as many basic categories as possible, and I’ll include three games for each.

Slay The Spire 2

Steam User Rating: 97% (Also, The Best New Co-Op Steam Game Of March 2026 So Far)

While browsing through Steam’s catalog, there is always that one game that has a tag that sparks a reaction of “wait, how does that work?” Slay the Spire 2‘s co-op classification drew that response from me… like, how does that work?!?

Well, as it so happens, multiplayer fits Slay the Spire 2‘s gameplay loop incredibly well. For the most part, co-op doesn’t really change the core formula, at least in relation to how battles play out. Each person has access to their own deck, loadouts, characters, Ancients, rewards, and merchants. Enemies attack both players simultaneously, which maintains the same structure as the single-player portion. The biggest difference is simple coordination, as players all throw their cards at the same time, leading to opportunities to synergize moves if done correctly. Slay the Spire 2 even has multiplayer-exclusive cards.

While still in early access, Slay the Spire 2 is already in great shape and is a pretty easy recommendation for fans of the original or even folks who are just into deck-builders. Co-op is a nice addition to the single-player, and both aspects are fleshed out enough to be selling points.

You can’t beat a good roguelike deckbuilder, and these are some of the very best.

Reanimal

Steam User Rating: 82%

By the team responsible for the original two Little Nightmares games, Reanimal is very much a spiritual successor to that series, albeit with one major twist: Co-op. Famously, Little Nightmares 2 features dual protagonists but no multiplayer, a set-up that worked well within the context of that game. Although offering a somewhat similar single-player experience, Reanimal was arguably designed with co-op in mind, as the story not only revolves around two siblings, but cooperation is also a central theme.

Should you play Reanimal if you are a die-hard fan of Little Nightmares? Well, the obvious answer is yes, but I would recommend tweaking your expectations to an extent. The 2026 game focuses far less on puzzles or gameplay in general, with the set design and atmosphere being prioritized. There is absolutely nothing wrong with that, but this change might not be exactly what everyone is craving. However, Reanimal‘s presentation, designs, tone, and world-building are absolutely top-notch, and it is a proper horror adventure.

Arc Raiders

Steam User Rating: 87%

Ever since it came out in October 2025, Arc Raiders has been the talk of the town and continues to be among the most active games on Steam. Considering it is not free to play, its short-term longevity has been impressive, and there is every indication that it will remain a fixture of the multiplayer scene for a long time to come.

Now, Arc Raiders is PvP with PvE, so you really need to be willing to engage in the former to get the most out of the game. Co-op isn’t an available mode, and you cannot just team up with a few friends and engage in a PvE-only playthrough. If that is what your party is craving, Arc Raiders will probably not fill that void. However, you can team up with friends to form a squad and explore (and fight) together, taking on both AI enemies and other players. Arc Raiders even has a “solo vs squads” mode.

Peak

Steam User Rating: 95%

One of Steam’s best online co-op games of 2025, Peak is built around a daily struggle to overcome a mountain. You and up to three friends must join forces to reach the top, a journey that changes every day. Built on a fantastic concept for a live-service game that players can revisit relatively frequently, Peak blends exploration and survival, along with a goofy sense of humor courtesy of the art style and the hilarious ways deaths can happen.

Best Co-Op Open-World Games

Here are a variety of options for the best co-op games that can be experienced in an open world setting.

As the map is swapped out every day, the game manages to keep things feeling fresh for a surprisingly long time, especially since there is also a wide selection of items that can be found. Co-op is 100% Peak‘s priority as well, even if solo runs are possible and fun.

Marvel Cosmic Invasion

Steam User Rating: 88%

The beat ’em up genre has been quietly going through a renaissance in the last couple of years, producing a few fantastic games that cater to both long-time fans and relative beginners. Tribute Games’ TMNT: Shredder’s Revenge is arguably the most popular beat ’em up of the last decade, and I would recommend it to pretty much everybody, regardless of their love for the genre. In 2025, the developer followed up that modern classic with Marvel Cosmic Invasion, which delivers an even bigger roster of playable characters while supporting up to 4 players in both online and local co-op. Although Shredder’s Revenge is arguably superior, Marvel Cosmic Invasion is nevertheless brilliant and well worth a playthrough for comic fans or just people who enjoy a good old brawler.

With over-the-top animation, gorgeous visuals, and versatile combat, this game brings together everything to create something truly special, and players can get quite a bit of mileage out of the roster. The campaign can be completed in a couple of hours, but the heroes are different enough from each other to warrant multiple playthroughs. Although awesome when played solo, co-op elevates the experience, encouraging groups to pick characters that complement each other. Really fun stuff.

Teenage Mutant Ninja Turtles: Splintered Fate

Steam User Rating: 85%

With Shredder’s Revenge, we have gotten a few pretty good TMNT co-op games in recent years. Splintered Fate isn’t quite as decorated as that beat ’em up, but it deserves praise for also being a worthwhile addition to not only the Turtles’ video game resume, but also the action roguelike genre in general. If I had to describe this game in one phrase, it would be “Hades but TMNT.” Dismissive as that might sound, there is no doubt that Super Evil Megacorp’s project was inspired by that heavy hitter; however, there is absolutely nothing wrong with using one of the best games of the last decade as a foundation to build something new. Despite their many similarities, Splintered Fate still 100% feels like a TMNT game, and co-op adds an extra dimension that really elevates the overall experience.

Be it locally or online, four players can team up to go on an adventure to rescue Splinter, a journey that will require repeat runs as they gradually accumulate Dragon Coins that can be used for permanent upgrades. Gameplay-wise, Splintered Fate is a fairly typical isometric beat ’em up, with players having a basic attack, a dodge, and two unique skills that can be swapped for new ones during an expedition. As always, when a room is cleared, every player gets a chance to pick either a new skill, run-based upgrades, coins that can then be used for permanent upgrades, or scrap that can be used at a venture during the current run. Simple but solid stuff, and each character feels different enough to justify their existence.

Elden Ring Nightreign

Steam User Rating: 86%

Nightreign is a weird game. Nobody asked for an Elden Ring spin-off that is a co-op roguelike with battle royale elements. Seriously, nobody! However, FromSoftware had more than earned the benefit of the doubt, so a lot of people were ready to give Nightreign a try for themselves. The thing is, if the game’s base description does not sound like something you might enjoy, then you will probably not love it. For better or worse, Nightreign delivers the exact experience it advertises, and you should not go in expecting something identical to Elden Ring.

Groups of three players jump into a relatively static map, where they must survive for three days while defeating enemies and acquiring loot. Along the way, they must fight mini-bosses and, on the third night, take down one of eight main foes. The latter are known as the Nightlords, and they are some of the best boss fights FromSoftware has ever designed; however, they are all intended for three players, so solo runs are really not recommended (despite technically being possible). Once you defeat all eight bosses, you just do everything again.

Schedule 1

Steam User Rating: 98%

TVGS’s Schedule 1 came completely out of nowhere and pretty much instantly took over Steam’s best-selling charts, establishing itself as one of 2025’s biggest surprise success stories (so far). Now, the game is still in early access, so anybody interested in jumping on board must be prepared for some rough edges and incomplete (or missing) mechanics. That said, the current version has more than enough content to keep a group of players busy for a long while, and Schedule 1‘s roadmap is quite exciting too.

If the official Schedule 1 roadmap is anything to go by, players have an awful lot to look forward to over the coming weeks and months.

Although playable solo without losing anything significant, Schedule 1 also supports 4-player co-op, allowing friends to work together to build a criminal empire. The multiplayer has some aspects that could use some work, but the feature’s implementation is quite good and, for the most part, does not have too many frustrating elements.

John Carpenter’s Toxic Commando

Steam User Rating: 80%

Honestly, I doubt John Carpenter’s Toxic Commando will feature in this recommendation list for long, but it warrants a mention for now. Are you a fan of Left 4 Dead? How about Back 4 Blood? Or World War Z? Yes? Great! Then you will almost certainly enjoy Toxic Commando. John Carpenter’s name aside, Saber’s co-op shooter is exactly the type of game you think it is. Alongside 3 friends, you blast your way through levels, killing hundreds, if not thousands, of zombies along the way.

Just to be clear, Toxic Commando manages to carve out a unique identity through its open-zone structure, vehicle incorporation, and mercenary characters, so it isn’t just a copy of everything that came before. However, it is effectively trying to scratch the same itch, and it does it relatively well. While I don’t know how replayable it will be in the long run, Toxic Commando is definitely good enough for at least one run through the campaign.
