Peak Sells 10 Million Copies, Proving Game Jams Still Launch Hits
The co-op climbing game born from a game jam has reached 10 million sales in just two months, making it one of 2026's biggest indie success stories.
Peak, the low-budget co-op climbing game that started as a game jam prototype, has officially crossed the 10 million copies sold mark. The milestone comes just two months after the game’s surprise launch in December 2025.
From Game Jam to Phenomenon
What makes Peak’s story remarkable isn’t just the numbers. It’s where the game came from. Originally prototyped during a 48-hour game jam, the small development team spent less than a year polishing the concept into a full release. The game’s premise is deceptively simple: climb a mountain with friends, using physics-based movement that’s equal parts frustrating and hilarious.
The formula clearly resonated. Within its first week, Peak had already moved over a million units, fueled largely by streamers and content creators who turned the game’s chaotic co-op moments into viral clips.
Why It Works
Peak taps into the same magic that made games like Human: Fall Flat and Getting Over It into cult favorites: accessible mechanics with a high skill ceiling, wrapped in moments that are inherently shareable. The difference is Peak’s focus on cooperative play, turning what could be a solo frustration simulator into a bonding experience.

What’s Next
The development team has hinted at post-launch content, including new mountains and competitive race modes. With 10 million players already in the ecosystem, Peak is well-positioned to become a long-term multiplayer staple.
Peak is available on Steam for $9.99, with a 10% launch discount still active. It supports 2-8 players in online co-op.
