Peak has been updated to version 1.50a in what will be the final content update of 2025 for the co-op climbing game. This update makes things feel festive and wintry with the airport getting Christmas decorations and some of the biomes getting a layering of snow, except Caldera as its too hot for snow to settle there. In addition, Aggro Crab and Landfall have stated that going forward updates will fewer, though more content is planned for 2026.
