PEAK’s Final Biome Update Will Arrive August 11 With GLOOM and THE CITADEL
The update will add GLOOM, THE CITADEL, new traversal tools, and Ascent 8 before CALDERA and THE KILN return to the rotation after two weeks.

PEAK’s final major update is scheduled to arrive on August 11. The update will add two new variant biomes, GLOOM and THE CITADEL, to the game’s rotation. The team shared the news in a new Steam announcement.
The new biomes will take the place of CALDERA and THE KILN in the rotation. For the first two weeks after launch, daily maps will feature only GLOOM and THE CITADEL. After that, the game will randomly choose between the new areas and the CALDERA and THE KILN rotation.
GLOOM and THE CITADEL join the rotation
The full v2.0.a patch notes reveal more about the final ascent. GLOOM has a purple, eerie setting built around a towering structure, while THE CITADEL sends scouts through a dangerous fortress packed with hazards. Strange statues have also begun appearing across the island. Their connection to the Scoutmaster’s original lost troop remains a mystery.
New gear and a tougher final ascent
Scouts will have several new ways to cross the mountain. The Jetpack replaces a backpack and uses assorted items as fuel, Warp Fungus can be thrown to discover its effect, and the Glider helps cover horizontal distances as long as its user has enough stamina.
Version 2.0.a also adds Ascent 8 and changes the rules for Ascent 7. Players will no longer be blocked from reviving during the latter challenge; instead, they will start cursed and gain more curse from revival. The update brings 10 new badges with matching cosmetics, along with Clown Luggage. Opening it provides a selection of unusual items, while the Lollipop, Cannon, and Balloon Bunch move out of Climber Luggage.
Existing auto-saves will no longer disappear when they are loaded. They will remain available until the run ends, whether the player wins or loses. Traditional Chinese localization is included as well.
Fake biome names hid the real destinations
Keeping the new areas secret was difficult because dataminers can inspect game files before content officially arrives. Rather than spend months trying to make the files completely leak-proof, Aggro Crab placed the genuine biome names alongside seven fake entries.
Some decoys sounded believable, including Grasslands and Temple. Others were much stranger: Skyblock, Hell, Heaven, and Mars also appeared as possible destinations. Wisconsin and Void showed up too, although they may have been codenames for the real biomes.
Paige Wilson walked through the file setup in a developer video.
Fixes and balance changes
Version 2.0.a fixes random fall damage when grabbing a wall without stamina, several co-op item-spawn issues, controller problems, piton prompts, poison effects, and visual bugs. The patch also makes carried scouts respond to Remedy Fungus healing and adjusts the blindness affliction, among other polish changes.
ROOTS receives the largest balance pass, with less aggressive beetles, smaller spore-mushroom radiuses, reduced spore effects, and less frequent windstorms intended to bring its difficulty closer to TROPICS. Campfires will also provide morale boosts to solo players, while several item spawn rates and the MESA’s height receive additional adjustments.
Once the update arrives, PEAK’s planned biome content will be in place. The developers plan to continue providing bug fixes and maintenance until the game reaches the stability they want, but they do not intend to turn PEAK into a live-service game with an endless stream of additions. Aggro Crab and Landfall are small teams, and both want to return to their separate projects after spending more time on PEAK than originally planned.
Mod support will remain part of the game’s future, but the developers do not plan to add Steam Workshop tools. They said cross-platform Workshop support is not possible and that many modders prefer other tools. The team will continue helping where it can, including sharing some source code with modders.
With the final update handled, the developers can focus more attention on bringing PEAK to consoles. Console versions are planned to support cross-platform play with the existing Steam community and other console players, with more news expected later in 2026.
A video accompanies the announcement, giving players another look at the update ahead of its August 11 release.
