―Official Description

The CM 000 Kelvin is a Premfully-automatic assault rifle in SAS: Zombie Assault 4 released by Ninja Kiwi as of the 26/11/2015 patch. It costs 400 NK coins or $39.99 USD, making it the most expensive Prem weapon in the game along with the Torment, Zerfallen, and the HIKS 888 CAW. CM 000 Kelvin appears in the store along with Ronson 5X5 and Vitriol

Not recommended for most level 100s, although it may serve a niche role on something of a support medic. At the level (level 50) it is initially unlocked however it can do pretty well with the standard augments, especially in certain events where large groups of bloaters need to be killed (freezes them in place so you can weave through them).


  • All Zombies hit will be frozen and zombdroids/bosses will be slowed, identical to the effect of Cryo Grenades.
  • Possibly due to latency, not all zombies in multiplayer modes will be frozen. Bloaters have a tendency to be successfully frozen more often than other zombies.


  • The number designation and name of this weapon is a reference to absolute zero, a temperature at which all motion in matter stops.
  • This weapon is the first of numbered CM weapon to break its naming system, whereas the number should be 4** for assault rifles, while this is 000, breaking the pattern but also implying onto what this weapon does with extremely low temperature.
  • 0 degrees Kelvin is equivalent to -459.67 degrees Fahrenheit or -273.15 degrees Celsius.
