It Takes Two requires exactly two players — there is no solo mode, no AI companion. Hazelight Studios built a game where every mechanic, every chapter, and every puzzle requires genuine cooperation and communication between two people. The game changes its systems roughly every 20 minutes, cycling through genres while maintaining an emotional throughline about a couple on the verge of divorce.
It won Game of the Year at The Game Awards 2021 for reasons that are apparent within the first hour. No other co-op game uses the medium so deliberately to say something about partnership. Buy two copies or use the Friend's Pass — one copy lets a friend play for free.
Josef Fares built a game where solo play is literally impossible — every mechanic reinforces that you need each other. The result is the most deliberate co-op design in gaming: 12 hours where the partnership is the game, not just the delivery vehicle for it.
For you if: You have one person to play with and want the best co-op experience available, regardless of genre preference.
Four space dwarves. Procedurally generated cave systems. Hordes of bugs. Deep Rock Galactic is the best co-op shooter because it was designed entirely around cooperation from day one — the game's classes (Driller, Scout, Gunner, Engineer) have distinct, complementary roles that make every composition feel different. "Rock and Stone" is more than a catchphrase; it's how the game makes you feel about your team.
The game is solo-friendly — a machine companion joins when you play alone — but the experience with three other dwarves is what the game was built for. Free content updates, a thriving community, and a developer that respects its playerbase. One of the best games of its generation.
For you if: You want a co-op shooter with distinct class roles, procedural levels, and a community culture that's genuinely warm.
The full 100-hour Baldur's Gate 3 experience is playable with up to 4 friends, each controlling their own character through every decision, combat, and dialogue. Playing together reveals how different people make choices and what they find funny or meaningful — the game's reactivity makes group playthroughs a shared narrative experience unlike any other RPG.
The co-op has quirks — one player controls dialogue, others can interject — but Larian's implementation is thoughtful. Playing BG3 with friends who are also invested in the story and character decisions is one of the best gaming experiences of the decade.
For you if: You want a deep narrative RPG experience shared with friends who enjoy story, character decisions, and tactical combat.
A $10 indie game by one developer that became a cultural moment. Lethal Company tasks your group with scavenging abandoned moons for a quota while avoiding monsters that kill you in increasingly terrifying ways. The horror is real — the comedy is also real, and often emerges from the same moment. Few games produce as many shared stories.
The genius is that failure is funny and death creates memories. Groups who play Lethal Company together accumulate inside jokes within a single session. It's the best example of emergent co-op storytelling in recent years — and at $10, the price-to-experience ratio is extraordinary.
For you if: You want a game that generates chaotic, memorable moments with friends and doesn't take itself too seriously.
Helldivers 2's Galactic War is a live meta-game where the entire playerbase collectively influences which planets are contested each week. The result is a co-op shooter where individual sessions feel like they contribute to something larger. Combined with Stratagems (called-in support weapons with input sequences), the combat depth is significant.
Arrowhead built a community-first game — the developers engage with players, balance against difficulty feedback, and treat the Galactic War narrative seriously. At launch it was one of the fastest-selling PlayStation PC ports ever. The community culture is excellent.
For you if: You want a co-op shooter with a live meta-game, strong community, and depth that rewards repeated play.
Divinity: Original Sin 2 lets up to 4 players each take an origin character with a fully voiced backstory through the entire campaign together. The co-op creates interesting moments — players can disagree on dialogue choices, trade items unfairly, or coordinate devastating combat strategies. The depth of its systems makes group play feel like a shared strategy session.
For you if: You want a deep tactical RPG with friends who enjoy planning, character builds, and debating story choices together.
Valheim's shared-world survival means your group builds a base together, hunts together, and fights bosses together — progress is shared across the world. The Viking aesthetic and stamina-based combat give it a distinct feel compared to other survival games. The game respects your time in ways many survival games don't: death isn't punishing, co-op is seamless, and there's always something meaningful to do together.
For you if: You want a survival-crafting game you can settle into for weeks with a consistent group, building and progressing together.
Monster Hunter: World and its expansion Iceborne represent the series at its most accessible while retaining the depth that made it a 20-year franchise. Hunting with friends makes encounters tactical discussions — who brings what, who baits which attack, how to coordinate a mount. The 14 weapon types mean each player brings a distinct combat identity to every hunt.
For you if: You want long-session co-op with crafting depth, distinct roles per weapon type, and a progression loop that stays interesting for 200 hours.
Portal 2's co-op campaign is a completely separate set of puzzles designed specifically for two players — not the single-player game with a second portal gun added. The puzzles require genuine communication: "put your portal there, I'll jump through mine here." GLaDOS's commentary on the co-op robots remains some of the funniest writing in gaming. At $10, it's an essential purchase for anyone with a puzzle-game friend.
For you if: You want a puzzle game that requires genuine communication and produces laughs through both success and failure.
Raft starts with one player on a 2×2 wooden raft in an infinite ocean and ends with an enormous ocean-liner built by a group of friends over 40 hours. The progression — from fishing scraps with a hook to building multi-story structures with solar panels and research stations — creates a satisfying arc that groups navigate together. It's the most accessible survival co-op on this list and consistently plays well with people who don't normally play survival games.
For you if: You want a relaxed co-op survival experience accessible to non-gamers, with visible progression and a clear shared goal.
