PEAK, the co-op climbing game from Aggro Crab and Landfall, arrives on Xbox Series X|S

PEAK, a cooperative climbing game in which players scale a mountain that changes every day, came out today on Xbox Series X|S, Microsoft Gaming said in a release dated Oct. 22. The game is a collaboration between Aggro Crab, a studio in Seattle, Washington, and Landfall, a studio in Stockholm, Sweden, which the release calls Team PEAK.¹

Players take the role of lost nature scouts who crash-land on a mysterious island and must climb the mountain at its centre to be rescued, either alone or in a group. The release says the game is built on working together, with players helping each other up ledges and placing ropes and climbing spikes for those who come after.¹

The Xbox version includes crossplay, so a scout troop can form across multiple platforms. It also ships with all content updates released so far, including additional biomes, cosmetics and features, according to Microsoft Gaming.¹

The release describes four biomes, each with its own hazards, and a map that rotates every 24 hours. Players scavenge for food and manage injuries, and every setback limits stamina, making the climb harder.¹

Aggro Crab is known for Another Crab's Treasure and Going Under; Landfall for Content Warning, Haste, Totally Accurate Battle Simulator and Stick Fight: The Game. The two studios became friends after meeting at a game developer conference in 2022, and after the success of Another Crab's Treasure and Content Warning they decided to collaborate on a small project.¹

That project began as a game jam, which the release defines as a timed event where individuals or teams create a game from scratch within a strict deadline, often following a secret or shared theme. The theme was discussed while the developers sat in a hot tub in Sweden, a couple of months before they travelled to South Korea for the jam.¹

Three Aggro Crab developers and four Landfall developers worked from a rented apartment in South Korea for a month, the release says. Microsoft Gaming framed the result as a game designed around friendship from the start.¹

PEAK was developed with friendship in mind from the very beginning.¹Microsoft Gaming

The release lists PEAK at $9.99. It does not say whether the game is available on other platforms beyond the crossplay mention, and it gives no sales or player figures.¹
