How to Survive the Cold in Subnautica: Below Zero

Cold suit unlocks after you scan 1 fragment (3 s a scan). The map holds 1 fixed pin in 1 area.

The databank's cold-weather advice (the Arctic Survival Almanac) tells surface explorers that high winds can bring on hypothermia quickly and that a good cold suit pays off. The suit's own entry lists it as rated to 133.8 Kelvin.

Cold suit is crafted at the Fabricator from 2 Fiber mesh, 2 Snow stalker fur. Counted down to raw materials that is 4 Creepvine sample, 2 Snow stalker fur. The game describes it as "An insulated suit to provide protection from the cold."

The suit takes 2 Snow Stalker fur, the gloves 1 and the helmet 1, so 4 in all, plus 8 Creepvine samples behind the fiber mesh (8 Creepvine sample, 4 Snow stalker fur). The map pins one loose Snow stalker fur in Glacial Basin at 17 m above sea level. Snow Stalkers are placed too: 35 pins (22 adults, 13 young), in Glacial Basin 26 and Arctic Spires 9. The databank's note on them is to avoid them; bright light and unpredictable noise are said to deter an attack. I did not find a drop table for the fur in the files.

The Fevered Pepper tree is placed in the world (79 spots). The databank says its fruit raises body temperature, and the Spicy fruit salad is made from it (1 Fevered Pepper, 1 Preston's Plant Leaf); its description: "A surprisingly delicious salad with warming effects." The Thermos holds a hot drink: 2 Quartz, 1 Titanium. The Reinforced Dive Suit, from 1 fragment (1 fixed pin, Lily Pads), is described as giving "enhanced survival in extreme temperatures".

The almanac suggests natural shelter or restorative hot springs on the surface and says that in a standard dive suit, water may offer safety from extreme cold. The map has 78 thermal pins, but the files do not say which of them are the hot springs the almanac means, and the steam vents are described as hot enough to burn a bystander, so I would not treat them as a heater.

Every number here is read from the game files of the Steam build of 12 Aug 2025. Fixed pins and recipes are exact. Spawn chances come from a model of the game's spawner tables and have not been checked in a running game. Anything the files do not hold is marked on the page.

I paraphrase the game's databank text and do not copy the logs; the numbers are the recipe table's and the pins'.
