Peak's Final Major Update Adds New Biomes and One Last Secret

Aggro Crab's co-op climbing game Peak gets its final major update on 11 August 2025, bringing new terrain and one last mystery for players to unravel.

The update, titled 'The Final Ascent' in Aggro Crab's announcement, introduces two new variant biomes: Gloom and the Citadel. These will cycle into the game's rotation, replacing two existing biomes — Caldera and The Kiln — so the climbing experience shifts each time you play. The developer has also tucked a new secret into the update, though details are being kept quiet for players to discover on their own (Eurogamer).

Peak, published by Landfall and available on Steam, is a co-op game where players climb a mountain together — think teamwork, rope management, and plenty of tumbling back down. The game has been updated with new content since launch, and this patch marks the end of that roadmap. Aggro Crab's own Steam news post also refers to the update as 'The Final Biome Update,' signalling that no further content drops are planned (Steam).

For fans, this means the climb is settling into its final shape. The new biomes give the rotation fresh variety, and the hidden secret offers one more reason to gather a group and push for the summit. After 11 August, Peak stands as a complete package — no more seasons, no more additions, just the mountain as it will be remembered.
