PEAK, a co-op climbing game published on June 16th 2025, had far surpassed the expectations of their developers Aggro Crab and Landfall Games. The $200,000 budget indie game sold over 1 million copies in it’s 1st week; now on the 3rd week since release and it is still breaking concurrent player records.

On the July 2nd, PEAK hit 176,478 Twitch viewers with the player count on Steam fluctuating around 100,000 everyday.

“Why did this stupid jam game sell more copies than Another Crab’s Treasure?”

Joked Aggro Crab on their social media.

Originally built for the Global Game Jam 2025; PEAK was quickly realised as an exciting new addition to the massively popular low-spec, co-op games dominating the gaming space.

Low-budget games with similar small indie teams like Content Warning (Landfall Games), R.E.P.O (Semiwork Studios), Phasmaphobia (Kinetic Games) are all massive successes in the recent years. Other popular titles such as Lethal Company (Zeekers) and Schedule 1 (Tyler ‘TVGS’) have been leading the player charts on steam despite being made by a single developer.

Studio head at Aggro Crab Nick Kaman, revealed he was jealous of Landfall Games’ Content Warning at the time, to the point it

“turned everything we know about game development upside-down.”

Then, a collaboration between Aggro Crab and Landfall Games began when Kaman contacted the studio before the Game Jam in Seoul, and were met with an enthusiastic yes. Majority of the development for PEAK took place during the month-long jam session in South Korea.

Kaman stated that

“We brought our computers to an Airbnb in Hongdae and locked tf in for a month. As soon as we landed, we beelined straight for the nearest IKEA and spent the day assembling office chairs and desks,”

PEAK had initially been pitched a year prior in their home country Sweden, by Aggro Crab creative director Caelan Rashby-Pollock.

Kaman continued

“it was the most fun I’ve ever had working on a game… the player experience often mirrors the development. Most of the design was driven by the question: ‘Wouldn’t it be funny if this happened’…”

On Steam, PEAK has over 35,000 reviews of which 91% are positive. As of writing, it is the platforms #3 best-seller.
