PEAK’s final major update, The Final Ascent, arrives on August 11, 2026 for PC through Steam. It is a free download for anyone who already owns the game, and it brings two new late-game biomes, GLOOM and THE CITADEL, into the climb.
Quick answer: The Final Ascent is confirmed for August 11, 2026. An exact launch time has not been announced. Based on how earlier major updates rolled out, expect it around 12 PM EDT, but treat that as an estimate and refresh the Steam page on the day.

What The Final Ascent adds
The headline additions are two new biomes built for the end of a run. GLOOM is a fog-filled, ghostly swamp, while THE CITADEL is a medieval fortress packed with hazards, including swinging flail traps. These two areas cycle into rotation alongside the existing CALDERA and THE KILN biomes rather than replacing them, so you still encounter the current late-game content mixed in.
The update also teases a monster that appears to hunt players as they climb, a shift for a game that has leaned on environmental hazards more than active pursuers. A voice-over from Scoutmaster Myres, voiced by Xalavier Nelson Jr., points to a more lore-focused ending, and new secrets are on the way.
New badges, outfits, and achievements
The update adds new achievements. The exact count has not been shared, but with two fresh biomes arriving, it is likely there will be at least 10 new badges to earn, along with outfits to unlock. These will be tied to progressing through GLOOM and THE CITADEL.
How to get the update
Why this is the last major update
The Final Ascent is the final major content update for PEAK. The game will still receive patches and hotfixes, but no additional biomes, cosmetics, or features are planned after this release. PEAK was never intended as a live-service title, and both Aggro Crab and Landfall Games are already working on separate new projects.
PEAK launched on June 16, 2025 and sold more than 10 million copies in its first year, growing from a short game-jam project into a co-op hit. With this update, the biome roster reaches what the developers call its complete form, closing the game out on a planned schedule.
