Indie climbing game Peak has achieved a remarkable milestone, selling over 10 million copies since its launch in June 2025. This success was highlighted during Gamescom Opening Night Live, where the figure was confirmed amidst a surge of interest following a significant discount and the release of a new Mesa update. Peak allows up to four players to engage in cooperative climbing while managing stamina and overcoming obstacles, and it has captured a significant player base on Steam with impressive concurrent user counts, even spawning knock-off games in Roblox.

What makes Peak so popular among players?

Peak's popularity stems from its engaging cooperative gameplay, where players work together to climb challenging mountains, navigate intricate obstacles, and manage resources. Coupled with frequent sales and updates that keep the game fresh, it has maintained a strong community and consistent player base, contributing to its swift sales growth.

Peak was developed by Aggro Crab and has quickly established itself within the indie gaming scene. By emphasizing cooperative play and offering an accessible but challenging experience, it aligns well with trends in multiplayer gaming, appealing to casual and competitive players alike. The game's rise also shines a light on the growing market for innovative indie titles that offer unique gameplay experiences outside the traditional AAA model.
