Peak Sells 10 Million Copies

Indie climbing hit Peak has officially sold 10 million copies according to Aliena Analytics analyst Rhys Elliott and Gamescom Opening Night Live host Geoff Keighley.

Elliott first reported the sales figure on Monday in his newsletter, saying it had sold 1.7 million copies last week and was expected to pass 10 million at some point on Tuesday. Keighley then confirmed the 10 million figure onstage at Opening Night Live. It’s the second indie game released in 2025 to pass this milestone, following R.E.P.O., which has sold 16.8 million.

Peak has seen significant success on Steam since its launch in June, and has been consistently listed as one of the most-played games on the platform. At the time this piece was written, it was sitting at about 88k concurrent players on Steam per SteamDB, just above Naraka: Bladepoint and just behind GTA 5.

That success was amplified last week, when a sale dropping it from $7.99 to $4.95 alongside the new Mesa update caused it to shoot up in sales and concurrent players. It reached 171k concurrent users on Sunday, and 1.3 million total users throughout that same day, per Alinea.

Peak is a survival climbing game developed by Aggro Crab, where up to four players climb a mountain together, overcoming obstacles and managing their climbing stamina as they go. The game’s sudden popularity has inspired various Roblox knock-offs, with the developer saying on social media that it would rather players pirate Peak than play a “microtransaction-riddled Roblox slop ripoff.”
