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

For the best Xbox Series X/S co-op games of all time, I had to include the purely focused team-based It Takes Two and Split Fiction. But also fun story-driven adventures you’ll enjoy with friends, like Elden Ring and Sea of Thieves. 

You can challenge yourself to the tough dungeons in Diablo IV and take on the god-like bosses of Remnant 2. Either way, you must remember to always watch each other’s backs.

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

Here are some of the most exceptional, best Xbox Series X/S co-op games of all time.

10. Sea of Thieves

You choose whatever role you like best in Sea of Thieves, and then set sail for adventures beyond the sea. Crewmates split tasks among themselves, whether it’s plundering mysterious islands, sinking enemy ships, or treasure hunting together.

This is the ultimate sea-faring, piracy experience for players looking to colab. It has a massive, shared open world full of over 50 side quests, hunting and fishing expeditions, sunken ships, both the natural and supernatural phenomena, and so much more.

9. Grounded

The biggest change in Grounded 2 is the ability to hop onto ‘buggies’ and explore the world on their backs. These come in all shapes and sizes, and help make covering the bigger world that extends beyond your backyard a lot more manageable to explore. 

Players can specialise in diverse roles, which you’ll balance out among yourselves in preparation for the relentless threats lurking in the shared world. You’ll search for secrets beneath grass, build makeshift weapons, and defend yourselves against crawlies in the dirt.

8. Gears 5

Among the varied multiplayer experiences that Gears 5 offers are the three-player and five-player Campaign, Escape, and Horde co-op modes. It offers both online and split-screen options, giving you plenty of ways to enjoy company. 

Depending on the mode you choose, you’ll either enjoy a story-driven campaign that progresses your character or objectives like planting a bomb in enemy territory and pushing back waves of enemies in the renowned Horde mode.

7. Remnant 2

Terrifying creatures and god-like bosses are tearing the fabric of reality, and you and your buddies need to team up to fight them off in Remnant 2. This is the kind of game that will challenge how well you work together, incorporating intense ranged and melee combat.

It’ll have you going up against the odds of success, getting better the more missions you take on. You can level up your chosen archetypes with active and passive bonuses, and then move from one strange world to another, cleansing them of destructive mythical creatures.

6. Forza Horizon 5

Forza Horizon 6 is here, with over 550 cars drawn from some of your real-world favorites. These gradually unlock after completing missions, and will continue to strengthen your car collection. You can drive them around the neon streets of Tokyo or take random road trips to the countryside.

As the series has focused on, this is another open-world racing game expanding the missions and places you can enjoy car culture. It can get as casual as you want with players who love cars as much as you do, and team up to complete racing challenges together.

5. It Takes Two

Unlike the other best Xbox Series X/S co-op games of all time on this list, It Takes Two is specifically built for teamwork. Without a partner, you cannot play this game. The characters themselves are a couple whose relationship is on the rocks, and they need to iron out their differences if their relationship is to survive.

And creatively enough, they do so via solving platforming and puzzle challenges together, creative because the couple is shrunk to the size of dolls, and the world around them is so strange when everything seemingly ordinary is maximized in size and scale. 

4. Split Fiction

Split Fiction follows the same path, focusing purely on a co-op experience in a bigger action-adventure. Combining the worlds of sci-fi and fantasy, writers Zoe and Mio must work together to find their way back home.

When you think that you’ve seen all of the ways you can work together to navigate the world and solve problems, you discover new mechanics and abilities that turn your experience so far on its head. It’s a co-op experience that keeps evolving every new level you unlock.

3. Baldur’s Gate 3

For players who want to be in control of their own stories and adventures, you can try out Baldur’s Gate 3. It brings tabletop RPG to a brave, new world of 3D settings your characters can run around and explore.

It’s a more immersive co-op experience, where you pick up side quests during exploration and discover secrets across a vast Forgotten Realms. And your movement allows for curious exploration, combining climbing, jumping, and dipping to the depths of the Underdark.

2. Diablo IV

The dungeons in Diablo IV aren’t for the faint of heart. They challenge you with formidable world bosses that require team effort to defeat. You have lots of action set piece moments in a dark open world, unraveling an absorbing story alongside friends. 

Dungeon-exploration is also about perfecting your game, and the robust character and loot customization should well-satisfy players looking to grow stronger and more capable after every run.

1. Elden Ring

The open world in Elden Ring deserves to be experienced with friends. Even when the prize is becoming the Elden Lord, the experiences that lead up to it are so complex yet seamlessly connected that it feels like an adventure of a lifetime. 

There are massive dungeons that harbor threats and the unknown. Meanwhile, the story weaves twists and turns from the dynamic world and characters you meet. So, hurry on co-op buddies. The Lands Between awaits.
