Peak Climbing Game Lands on PS5 October 22 with Crossplay

By Jake Campbell•16 October 2026

Team Peak, a collaboration between Seattle-based Aggro Crab and Stockholm’s Landfall, announced that its co-op climbing game Peak will launch on PlayStation 5 on October 22.

The two studios became friends after meeting at a developer conference in 2022. Following the success of Aggro Crab’s Another Crab’s Treasure and Landfall’s Content Warning, they decided to collaborate on a smaller project together.

To celebrate their friendship, the teams initially developed Peak as a one-month game jam in Seoul, South Korea, in February 2025. Three Aggro Crab developers and four Landfall developers worked from a rented apartment, building the game under deadline pressure.

The concept had been discussed earlier by developers sitting in a hot tub in Sweden, months before traveling to South Korea for the jam. A game jam is a timed event in which teams create a game from scratch within a strict deadline, often following a shared or secret theme.

The result is Peak, described as a co-op climbing game where “the slightest mistake can spell your doom.” Players take on the role of lost nature scouts stranded on a mysterious island, with their only hope of rescue being to scale the mountain at its center.

After the jam, the team returned home—Landfall finishing Haste and Aggro Crab working on Peak and other projects. They reunited in Sweden in June to complete the game together, also celebrating the Swedish tradition of Midsummer.

The studio says Peak is built around friendship, both in development and gameplay. One central rule: never abandon a friend in need. With the PS5 launch, crossplay has been added so players can climb with up to three friends regardless of platform.

In Peak, players climb through four biomes toward the summit, each featuring its own life-threatening obstacles. Players must scavenge for questionable food to survive and manage injuries carefully—each setback limits stamina, making it harder to climb.

Hazards encountered across the biomes range from tornadoes and poison clouds to birds and zombies. Runs can be customized to make things easier or harder depending on what a player’s “scout troop” prefers.

The PlayStation 5 version includes all content updates, biomes, and new items the game has received since its initial launch. The studio invites players to gather their troops for Peak on PlayStation 5 October 22.
