PEAK Update v1.20.a Drops The Mesa and New Gear

Version 1.20.a introduces the Mesa biome to replace Alpine for one week, alongside 10 new badges, cosmetics, and survival items.

Landfall and Aggro Crab are expanding PEAK with a scorching desert map, fresh survival gear, and critical quality-of-life additions in version 1.20.a.

The Mesa Biome and New Gear

The Mesa steps in to replace the Alpine biome, appearing in every single run for its first week before joining a random map rotation. Along with the sandy terrain come 10 new badges paired with cosmetic rewards. Scouts can stock up on new items like Balloons, the Scout Cannon, Parasol, Sunscreen, Aloe Vera, and Dynamite, plus a few hidden surprises including a potential secret inside The Kiln.

Environment and Balance Shifts

Survival conditions have shifted across the mountain. Fog in the Tropics rolls in slightly slower. Heat status now decays faster overall, though the delay before decay kicks in has been stretched out, and hot rocks in the Caldera deal heavier Heat damage.

Accessibility, UI, and Bug Fixes

Arachnophobes can turn on the new Bug Phobia Mode to hide spiders and other creepy-crawlies inhabiting the Mesa. Controllers can now navigate the Settings menu. Performance climbs across the board, alongside fixes for teleport glitches after a rusty piton breaks, improper Naturalist Badge unlocks, backpack inventory locks while passed out, luggage clipping, and looping audio on the Bugle of Friendship.

Why this patch matters

Version 1.20.a shakes up PEAK runs with guaranteed desert exploration, fresh survival tools, and a much-needed arachnid display toggle.
