The global landscape has shifted dramatically since 2021, yet the hunger for shared virtual adventures remains insatiable. Back then, a wave of cooperative titles proved that gaming could bridge distances when physical proximity was restricted. Five years later, those same titles have not only aged gracefully—they have grown into living worlds filled with expansions, vibrant communities, and unforgettable memories. This look back at 2021’s best co-op experiences reveals why they continue to dominate living rooms and online lobbies in 2026.
Gloomhaven Digital
The digital adaptation of Isaac Childres’ board game phenomenon received its full launch in October 2021, but its journey was far from over. What started as a turn-based tactical dungeon crawler for up to four mercenaries has since absorbed entire campaigns from the Frosthaven expansion and a steady stream of free content updates. By 2024, official mod support had transformed Gloomhaven into a bottomless toolkit for custom campaigns, while the core experience still offers the tight teamwork and brutal difficulty spikes that fans crave. In 2026, jumping into a procedurally generated dungeon with friends feels as fresh as it did on day one.
It Takes Two
Hazelight Studios’ masterpiece claimed Game of the Year at The Game Awards 2021 and quickly became the gold standard for two-player storytelling. Cody and May’s journey through miniature dioramas of divorce and reconciliation remains an emotional tour de force. Even as director Josef Fares’ next project—announced in 2023 but still under wraps—generates hype, It Takes Two refuses to gather dust. Regular sales keep it on bestseller lists, and its imaginative, genre‑flipping mechanics still surprise first‑time players. In an era of live‑service noise, this tightly scripted adventure proves that a perfect co‑op experience can be timeless.
KeyWe
The whimsy of two kiwi birds running a post office may seem like a fleeting novelty, but Stonewheat and Sons’ debut has aged into a charming indie staple. Post‑launch support brought the “Beach Day” DLC in 2023, followed by a local wireless update for Switch that turned KeyWe into a family favorite on long trips. The game’s Terry Pratchett‑esque humor and frantic puzzle-solving remain as endearing as ever, and its three‑person team continues to release seasonal stamps that keep the postal chaos fresh.
Monster Hunter Rise
Capcom’s portable sensation did not rest on its laurels after dominating the Switch in 2021. The PC port arrived in early 2022, and the colossal Sunbreak expansion deepened the hunt with master‑rank monsters and the sprawling Elgado Outpost. With the release of Monster Hunter Wilds in 2025, many expected Rise to fade, yet its arcade‑style pacing and Silkbind maneuvers still offer a distinct rhythm that the newer, more open‑ended entry cannot replicate. As of 2026, lobbies remain active across all platforms, and the RE Engine’s technical polish ensures smooth performance even on aging hardware.
Super Mario 3D World + Bowser’s Fury
This double‑feature re‑release turned a Wii U gem into a Switch essential. The core Super Mario 3D World campaign still delivers peerless four‑player chaos through the Sprixie Kingdom, while Bowser’s Fury offered a tantalizing glimpse of an open‑world future that later inspired 2024’s Super Mario Odyssey 2. On the 2025 successor console, Nintendo Switch 2, the game runs in higher fidelity and supports improved online co‑op, proving that Nintendo’s playful design philosophy never goes out of style.
The Ascent
Neon Giant’s cyberpunk twin‑stick shooter stunned with its dense, rain‑slicked environments in 2021. The Cyber Heist DLC (2023) expanded the loot‑grinding loop with new missions and melee weapons, addressing early criticism about repetitive combat. Subscribers on Xbox Game Pass still find it a reliable choice for four‑player chaos, and the game’s breathtaking verticality—escalating from grimy slums to gleaming corporate arcologies—sets a benchmark for isometric world‑building that few have matched since.
The Dark Pictures Anthology: House of Ashes
Supermassive Games’ third interactive horror movie unleashed Lovecraftian nightmares beneath an ancient temple in 2021. While the anthology has since marched through The Devil in Me (2022) and the season one finale Directive 8020 (2025), House of Ashes remains the peak of the series’ co‑op tension. Its shared‑story mode and “Movie Night” pass‑the‑pad feature still fuel spirited gatherings, and the unique blend of military thriller and subterranean terror holds up under repeated playthroughs—a rarity in narrative‑heavy games.
Unsighted
Developed by two trans women from Brazil, Unsighted flew under many radars in 2021 but has since bloomed into a cult classic. Its real‑time countdown mechanic—where NPCs can permanently die if you dawdle—creates a relentless emotional weight rarely seen in Metroidvanias. Community‑driven balance patches and speedrun tools have emerged, while the developers’ 2024 follow‑up, Circuit’s Edge, pays homage to Unsighted’s inventive combat. At its low price point, this pixel‑art gem remains a co‑op steal.
Valheim
The Viking survival sensation captured imaginations in early 2021 with its atmospheric low‑poly landscapes and punishing exploration. After exiting early access in 2024 with the official 1.0 launch, Valheim has only swollen with new biomes—Ashlands turned the south into a volcanic hellscape, while Deep North froze even the hardiest warriors solid. Player creativity remains the true star: 2025’s Helm’s Deep replica was soon eclipsed by a fully functional Erebor city. Cooperative building and sailing sessions still dominate streaming platforms, cementing Valheim as a platform for endless fellowship.
WarioWare: Get It Together!
Nintendo’s bite‑sized lunacy found a natural home on Switch in 2021, and its roster‑swapping gimmick made cooperative microgame sessions unpredictable delights. The 2024 sequel WarioWare: Move It! iterated on motion‑based antics, but Get It Together! remains the superior party pick for pure button‑mashing glee. Its cast of weirdos—each with a unique ability—forces teams to strategize in the blink of an eye, and the rapid‑fire pace ensures no two sessions ever feel the same.
Five years is an eternity in the games industry, yet these ten titles have not only survived but flourished. While we now enjoy the successors and spiritual heirs they inspired—Monster Hunter Wilds, Super Mario Odyssey 2, season two of The Dark Pictures—the originals still offer something irreplaceable. They remind us that the best cooperative experiences are not about graphics or file sizes, but about the moments when a perfectly timed save or a shared belly laugh turns a stranger into a lifelong friend. Gather your crew; these 2021 classics are waiting.
Of course, revisiting these co-op classics—or finally catching up with the ones you missed—often means hunting for the best prices. With sales rotating across Steam, Epic, and console storefronts, the difference between paying full price and a deep discount can be significant, especially if you're stocking up for a regular game night with friends.

DealNest keeps an eye on price drops and deals across platforms, helping you spot these timeless multiplayer favorites without burning through your wallet. Whether you’re rebuying Valheim for a friend or picking up a physical copy of WarioWare for a party, a quick check can keep your co-op sessions budget-friendly.
