Co-op Games Earn $4.1 Billion on Steam

In the first half of 2025, co-op games on Steam collectively generated $4.1 billion in revenue, setting a new record for the genre over a six-month period. This figure marks an increase of nearly 11 percent compared to the same period in 2024 and reflects an ongoing upward trend that began during the pandemic-related gaming surge. Steam’s five best-selling new releases so far this year are all co-op-based, underlining the sustained demand for shared gameplay experiences across the platform.

The rise of co-op games on Steam has been building steadily for more than a decade. Co-op titles now sit at the intersection of social engagement, replayability, and creator-driven appeal - factors that have become essential in maintaining player interest and visibility on digital storefronts.

Steam’s algorithms tend to favor games with strong user ratings and extended engagement, helping co-op titles remain prominent on the charts. These characteristics have made co-op especially effective for independent developers who do not have the marketing budgets of larger studios. For many players, co-op gaming offers a way to connect with others in a low-pressure environment, which has contributed to its broader adoption.

Indie Co-op Titles Deliver Strong Performance

Independently developed co-op games have seen notable commercial success in 2025. One of the standout titles is R.E.P.O., a multiplayer horror game that launched in February. Combining accessible gameplay, viral potential through jump scares and humorous physics, and a low barrier to entry, R.E.P.O. has sold 16.4 million copies on Steam and generated $128.2 million in revenue. The game appeals to fans of earlier indie successes such as Phasmophobia and Lethal Company, and its player overlap with these titles reflects strong community interest in the subgenre.

Another indie title, Schedule I, has gained traction for its unique concept and cooperative gameplay. Set in a darkly comedic world centered on drug dealing, the game features simple controls, pick-up-and-play accessibility, and chaotic multiplayer action. It has now surpassed 9 million copies sold and has brought in $137 million in revenue on Steam.

Also noteworthy is PEAK, a mountain-climbing game with physics-based mechanics and in-game voice proximity chat. The title has sold over 7 million copies at a modest price point of $7.99, totaling $42 million in revenue. These results illustrate how smaller-scale games can generate substantial returns when they effectively leverage social play and low pricing.

Co-op Games in the AAA and AA Space

Co-op gaming has not been limited to indie studios. Larger developers and publishers have also released major co-op titles this year, contributing significantly to the genre’s commercial footprint. Monster Hunter Wilds, a new entry in the well-known action RPG franchise, has become Steam’s highest-grossing new release of 2025. It has sold 6.3 million copies on the platform and earned over $380 million in revenue. Additional copies sold on PlayStation 5 and Xbox bring its total well above 9 million units.

Hazelight Studios, the developers behind It Takes Two, released Split Fiction earlier this year. The game blends narrative storytelling with platforming and includes commentary on contemporary themes such as generative AI. With 2.6 million copies sold on Steam and over $100 million in revenue, the title has also found success on consoles, pushing total sales above 6 million units. Notably, each purchase includes a friend pass, allowing players to invite a friend to join at no extra cost.

Another significant release is Elden Ring: Nightreign, a co-op-focused PvE title from FromSoftware. As a spin-off of the original Elden Ring, Nightreign was developed using many of the original game’s assets and has achieved efficient production and strong sales. It has sold 2.8 million copies on Steam and generated $92 million in revenue, with additional units sold on PlayStation and Xbox.

While daily active user numbers have declined over time, a recent update has brought renewed interest to the game. The project also marked the directorial debut of Junya Ishizaki, signaling a transition in creative leadership at the studio, with longtime director Hidetaka Miyazaki continuing in a supervisory role.

Co-op’s Growing Role in the Gaming Market

The consistent commercial performance of co-op titles throughout 2025 suggests that the format is no longer just a feature but a key structural component of the games market. From accessible indie releases to large-scale franchise entries, co-op games are being embraced across genres and budget levels. Their success reflects broader player preferences for socially driven gameplay and lower-pressure alternatives to competitive multiplayer.

As the year progresses, additional co-op releases are expected to build on this momentum. Developers are increasingly recognizing the value of designing games around shared experiences, and current revenue trends indicate that co-op is likely to remain a central pillar of success on Steam and other platforms.
