The developer identifies portable heaters, improved thermal clothing and crafted heat packs as Cold Zone preparation. Its September 25 pre-release update also describes a revised Cold Zone effect. No safe exposure time, temperature threshold or exact launch loadout has been verified.
The patch corrects the Moon Cult set’s displayed cold resistance from −29°C to −27°C. This is a display correction, not evidence of a changed survival threshold or a tested safe route.
The source names these categories but does not give their statistics. The developer associates Cold Zones with rarer materials and technology, making preparation relevant before a gathering trip.

Current protection and the requirement for an upgrade
This is conservative planning advice inferred from the described hazard, not a tested threshold. If protection fails to stabilize your condition, abandon the trip and reassess the equipment. Do not extend a run because an old video survived for a particular number of minutes.
Choose one resource objective and a known return shelter.
Verify the available protection using current item descriptions.
Watch the actual heat, energy and stamina indicators during a short approach.
Return before the margin for the return trip disappears.
The November development update describes temperature rebalancing and simpler indicators. On September 25, the developer also announced a revised Cold Zone effect and eight additional valuable items in these areas. The post does not identify those items, give effect values or establish behavior in a released build. Treat older screenshots as context, not a safe-time rule; record the build and equipment alongside any successful trip you want to repeat.
The October 3 playtest patch says the tutorial Cold Zone now uses standard Cold Zone temperatures and an outdated survival hint in Hunter’s Glade was replaced. Earlier tutorial footage may therefore show different conditions. The notes give no numerical temperature or safe exposure time, and the change has not been tested here in the launch build.
