The latest indie sensation on Steam isn’t a shooter or a survival horror—it’s Peak, a co-op climbing game that just hit 1 million copies sold in under a week. Launched on June 16, Peak has quickly become one of the most-played games on Steam, climbing its way to the top of the charts during its first weekend.
What Is Peak?
Peak is a procedurally generated, cooperative climbing experience for up to four players. Developed by Landfall and Aggro Crab, the game casts players as a group of stranded nature scouts trying to scale treacherous terrain and survive together. With limited stamina, item scavenging, and survival mechanics, coordination is key.
The real chaos—and charm—of Peak comes from its proximity voice chat, which encourages players to work together while often devolving into hilarious shouting matches. Think Only Up! meets Lethal Company, but in a climbing simulator with unpredictable terrain and gravity-defying moments of failure.
Twitch’s New Favorite Game
Peak owes much of its meteoric success to Twitch streamers and content creators who instantly latched onto the game’s meme-worthy moments. Like Phasmophobia and REPO before it, Peak offers a perfect mix of co-op comedy, clumsy teamwork, and repeatable chaos.
Massive Sales, Tiny Price
At just $3.99 (on sale now for $2.47), Peak is not only fun—it’s affordable. According to SteamDB, the game has outperformed major AAA titles like Dune: Awakening, Dead by Daylight, and even Elden Ring: Nightreign in revenue, despite the massive price gap.
Aggro Crab took to BlueSky to thank fans for the overwhelming support, celebrating 1 million units sold and a massive community rallying around the game in just six days.
