PEAK Beta Patch 1.61.b Notes - April 2026

Cold nights are back in Ascent 5+ after BETA branch Patch 1.61.b landed on PEAK's beta branch today. If you've been breezing through late-game climbs without the temperature penalty, that particular free ride is over.

The most impactful fix here is probably the rope hitching issue. If your squad was placing a lot of ropes in a single biome, the game was grinding to a halt, and that's a serious problem in a co-op climbing game where ropes are half your toolkit. Beyond that, a few reconnection edge cases have been ironed out: players dropping back into the Kiln after a Caldera disconnect will now respawn dead unless a revive statue was used, and a separate bug that was preventing reconnecting players from spawning their scout at all has been squashed.

Custom runs also get some housekeeping. Guidebook pages no longer spawn in them, and multi-run achievement progress won't accumulate there either, which keeps the mode honest. Small stuff, but the kind of consistency fixes that stop custom runs from feeling like a unintended exploit route. The complete notes are below.

How do I join the beta branch?

To access the PEAK public beta go to steam and find peak in your library.
Find the "gear" icon or right click the game and click "Properties" and a new window will appear.
In the new window find the beta section and enter the beta password: playpeakbeta
That will unlock the beta that you can now select in the beta participation drop down.

Night will once again be cold in Ascent 5+ and on custom runs when the setting is active
Players that disconnect in Caldera and reconnect in the Kiln will come back dead unless the revive statue was used to revive other scouts
Guidebook pages will no longer spawn in custom runs
Progress towards multi-run achievements won't accumulate in Custom Runs (where all achievements are supposed to be disabled)
Fixed a case where reconnecting players would fail to spawn their scout
Campfires' lit status will now sync when a player joins after a campfire is lit but before it burnt out
Fixed a major issue with ropes that was causing the game to hitch if many ropes were placed in the same biome
