Cryogenics is the study of the production and behavior of materials at very low temperatures.
Background
Before the Great War, several companies and government agencies are known to have produced various types of cryogenic technology. The technology varied significantly, from cryonic life preservation systems, containment devices, and weaponry such as cryo grenades and mines. In response, the public would remain skeptical of the technology and its safety.[1]
Cryonics
Cryonics is the low-level temperature preservation of humans and animals in suspended animation by slowing their vital functions, for the purposes of preserving them and keeping them alive for extended periods of time.
Cryogenic weapons
Fallout 3
Mothership Zeta
The alien civilization aboard Mothership Zeta made cryogenics a core aspect of their invasion and their research. Elliott Tercorien harnessed this to create cryo grenades and cryo mines.
Fallout 4

An experimental weapon called the cryolator was developed by the overseer of Vault 111. It could propel super-chilled nitrogen gas at a target,[2][3] slowly freezing them as they were exposed.
Fallout 76
The cryolator was available for use in Appalachia in 2102.
Wastelanders
Cryogenic weapon modifications and ammunition were made available upon the Settlers and Raiders resettlement in Appalachia.[4]
Steel Dawn
Additional cryogenic weapon modifications and ammunition were made available via the Brotherhood First Expeditionary Force's arrival in the region.[5]
Notes
- Cryonics and cryogenics, while sometimes erroneously used as synonyms, are in fact two different terms. Cryogenics is the study of the production and behavior of materials at very low temperatures, while cryonics is the low-level temperature preservation of humans and animals in suspended animation.
Appearances
Cryogenic technology appears in Fallout 2, Van Buren, Fallout 3, its add-on Mothership Zeta, Fallout: New Vegas and its add-on Old World Blues, Fallout 4, Fallout 76, the Fallout TV series and Fallout Tactics. It is also mentioned in the Fallout: New Vegas add-on Dead Money.
