Peak climbs past 5 million sales in under a month, earning devs millions off a month-long jam

It hasn't even been a complete month since the release of Peak, yet the game is in talks everywhere - from streams on Twitch to short-form content on YouTube and Instagram Reels. The co-op climbing game, which amassed a huge player base shortly after launch, has now hit another critical milestone. 26 days after launch, 5 million copies of Peak have been purchased on Steam globally - which is a huge achievement for an indie title of this scale. 

The announcement came via developer Aggro Crab’s social media - who worked alongside Landfall for this game. Peak's success has been nothing short of viral, built around a simple idea: climb absurdly tall mountains and clear biomes with your friends (or by yourself) using ragdoll-like physics and proximity voice chat. It’s this mix of challenge and humor that’s helped the game explode across both the streaming and social video landscape.

At first glance, with a launch price of $7.99 and 5 million copies sold, the gross revenue would be about $39.95 million. But that figure doesn’t hold up on closer inspection. The game launched with a $4.95 sale price for its first week, meaning a huge chunk of copies were likely sold at a discount. Assuming an even split between full-price and sale-price buyers, the more realistic revenue range falls around $23.7 million before Steam’s cut.

Steam’s revenue share takes 30% up to $10 million, and then drops to 25% for revenue between $10-$50 million, and 20% beyond that. With those numbers in mind, it’s likely the developers have taken home around $18 million in net earnings so far - though that number could be lower due to regional pricing. Looking at SteamDB estimates, international buyers may be paying up to 52% less than the US price in some regions.

Even with conservative estimates, that's a huge return for a project that reportedly started as a weekend idea. And with the game still climbing the charts and benefiting from word-of-mouth momentum, Peak is shaping up to be one of the breakout indie success stories of 2025.
