Peak

PEAK is a cooperative climbing game developed by Landfall and Aggro Crab and published by Aggro Crab. It released on Steam for Windows on June 16, 2025. The game places up to four players on an island wilderness dominated by a mountain at its center. Reaching that summit is the stated route to escape. Instead of assigning classes or giving players firearms, PEAK makes ascent its central challenge: players grab ledges, pull themselves upward, manage their footing, and help companions negotiate dangerous routes. The game supports online cooperative play and proximity voice chat, making careful conversation part of coordination. Every expedition requires attention to the climbers’ condition. PEAK uses a stamina system, so strenuous movement and difficult holds can leave a player unable to continue without a pause. Falls and other hazards can inflict injuries, including effects that reduce a character’s capability. Food and other supplies found during a run can be used to restore strength or address problems. Players can carry and pass equipment, and they can physically assist one another, including hauling a teammate upward. That shared vulnerability gives the game its characteristic cooperative tension: an individual mistake can become a group emergency when somebody is stranded. The island is organized into distinct biomes rather than a single unchanging cliff. PEAK’s launch version includes the Shore, Tropics, Alpine, and Caldera areas, each presenting a different stage of the climb. The terrain layout changes on a daily basis, giving all players the same rotated island for that day while preventing memorization of one permanent route. This daily design also supports repeated attempts beyond finishing once. As climbers advance, they encounter useful and unusual items, while the changing environment introduces new risks. The route therefore asks players to make choices about detours, supplies, recovery, and whether the party can continue. PEAK emerged from a collaboration between two studios associated with earlier games. Landfall is known for Totally Accurate Battle Simulator and Content Warning, while Aggro Crab made Going Under and Another Crab’s Treasure. The teams created PEAK during a month-long game jam before releasing it as a commercial project rather than leaving it as an internal prototype. The game’s Steam description calls it a cooperative climbing game in which the slightest mistake can spell doom. That framing fits its design: success depends on relaying information, sharing resources, choosing a route, and getting all alive climbers safely at the mountain’s summit.
