10 Best Xbox Series X/S Co-op Games of All Time in 2026

Whether your friend is close by or far away, you can still enjoy gaming sessions together. The local co-op option offers you the chance to game on the same screen, next to each other. Or you can join online servers with strangers looking to explore open worlds and fight monsters together. 

Either way, the best Xbox Series X/S co-op games of all time are a great starting point for catching up with friends, enjoying precious time together, and potentially making new friends online.

What is a Co-Op Game?

A co-op game is about players working together toward a common goal. You might split objectives among yourselves or communicate and coordinate your next moves against a common enemy: the values cemented in “teamwork makes the dream work.”

Best Xbox Series X/S Co-op Games of All Time

For the smoothest refresh rates and fast response times, you’re better off playing games on the current-gen consoles, starting with the list of the best Xbox Series X/S co-op games of all time below.

10. Sea of Thieves

Looking for the complete pirate treatment? Sea of Thieves is it, with its flurry of mischievous quests to get up to with friends. You can go treasure hunting, sailing out into the horizon, and exploring unknown islands and beyond.

Get ready to run into rival pirates, too, where you can engage them in naval combat or plunder their treasured goods. Moreover, you might solve riddles, among many more sub-quests.

9. Grounded

A once-in-a-lifetime opportunity to experience what it’s like to be the size of a bug presents itself in Grounded. You’re shrunk down enough to have glass blades towering above you, and ants become your worst adversaries. 

It’s an incredible out-of-body experience to think and respond differently than you might otherwise do as a full human. When your survival instincts against nature are the unexpected, and the weapons you use are makeshift tools you fashion out of the twigs lying about.

8. Gears 5

For a grittier touch to first-person combat, you can try out Gears 5. Here’s where you’ll need your elite squad of pro fighters and gunners, taking on other players in PvP or against the environment in PvE. 

The campaign is also exhilarating when you dive headfirst into full-blown war and enjoy a high-stakes story that intertwines complicated familial connections and survival in a world crumbling down.

7. Remnant 2

Among the best co-op experiences you’ll enjoy with friends is taking down mighty beasts, when everyone has to pull their weight, whether aggression, sustaining damage, or providing healing and ammo support.

Remnant 2 ranks high up on the list of the best Xbox Series X/S co-op games of all time. It’s a dark world taken over by deadly creatures and towering bosses. And your team explores this brave new world, running into mythical creatures, and clearing quest lines one dungeon at a time.

6. Forza Horizon 5

Nothing like racing together, enjoying the beautiful vistas and stunning sunsets of Mexico City. You’re a part of a team of car enthusiasts, attending festivals and participating in dynamic racing events all across the open world. 

The cars you can unlock in Forza Horizon 5 seem practically endless, as do the vast tropical landscapes you can both casually and competitively race through.

5. It Takes Two

Even the story itself in It Takes Two tells of a couple whose marriage is in trouble. And the only way they can resolve their issues is by working together, however challenging or frustrating it gets.

But therein lay essential lessons in patience and teamwork. Most puzzles and obstacles require both partners to sync their actions and movements. And don’t worry, there are plenty of laugh-out-loud moments, too, traversing the world in the form of shrunken dolls.

4. Split Fiction

For a more action-oriented It Takes Two-like co-op experience, you can consider Split Fiction. The story that merges mythological and sci-fi fantasy worlds is intriguing from the get-go. And so is the gameplay, introducing new mechanics in almost every new level. 

You enjoy a consistent stream of varied challenges: riding gravity-bending motorbikes, fighting an evil cat, and beating a monkey in a dance battle, among many more fun distractions.

3. Baldur’s Gate 3

Dungeons & Dragons has just gotten better, thanks to Baldur’s Gate 3’s brilliant world design and gameplay. It’s a vast and diverse world filled with secrets and quests to discover with friends. 

Every gaming session is an adventure told via stunning cinematic storytelling. And it comes with lots of opportunities to loot, battle, and even build romantic relationships with the NPCs you meet. 

I might go as far as to say that Baldur’s Gate is the very epitome of the best RPG and the best Xbox Series X/S co-op games of all time.

2. Diablo IV

And as far as dungeon-crawling goes, Diablo IV ranks high up. The hack-and-slash combat is addictive, along with its heavy looting and satisfying gameplay loop. You find yourself deeply intrigued by Diablo’s dark fantasy world, wanting to get better at progressing to the highest ranks.

For a dungeon-crawler, you want that constant sense of reward and progression. And Diablo not only delivers with its smooth gameplay but also deep customization and loot. It’s all about skill here, and gaining XP every chance you get to return to the Sanctuary.

1. Elden Ring

It shouldn’t come as a surprise that Elden Ring offers the best co-op experience, especially with the strong modding community. Your team will get the choice of engaging in intense boss fights or simply exploring the ever-evolving open world. 

It’s easier to take down the most fearsome bosses with friends and complete areas you’re stuck in. Plus, you can even find more skilled players who help you in areas you’re struggling to clear. 

And during the downtime, enjoy exploring and discovering unique builds. This is an open world that feels alive and vibrant, and an engaging place that quickly starts to feel like a perfect dream second home.
