Subzero is an official Krunker map created by mapmaker CrispyCrust. It was added in update v.1.1.0.

As its name suggests, it is defined by heavy amount of snow present on the map. The structure shown in the image to the right is often considered the center of the map, as many paths lead here and the neighboring church-like room. There are quite a few long-range channels in the map and even more for mid-range encounters. The abundance of turns in the map also allows for some close-range combat. There are many wide open areas like the church and fountain, mentioned earlier. It is one of two maps that feature a fountain, the other is old Oasis. There is also parkour in this map which is very hard to complete. It was added in the easter update.

Subzero was visually overhauled in v5.6.4 by Jerm Hunter

Similar to the Burg overhaul, Subzero hasn't had it's layout changed since it's previous version. Subzero now appears to be situated at a ski resort scattered with pine trees and flanked by cable cars. Tall mountains are apparent at a distance. The fountain in the middle which was prone to campers has been replaced with a cable car pole. Other notable details around the map are the presence of elevators leading to the cable car and toy shops with gifts, a decorated christmas tree and a KPD Officer on display.
