Fallout 4 loading screen hints

The Cryolator is a unique weapon in Fallout 4.


While waiting to the all-clear signal from Vault-Tec, the overseer of Vault 111 tinkered with some components and chemicals around the Vault. The Cryolator was the result, a prototype that made cryonic freezing portable.[1]


The Cryolator is similar to the flamer, but propels super-chilled nitrogen gas instead of flammable liquid fuel.[2][3] Consistent exposure to the cloud of cryonic material will eventually freeze most enemies (although large enemies like super mutant behemoths and mirelurk queens cannot be frozen).

The weapon uses rare and expensive ammunition rapidly, meaning discretion must be exercised for continuous use of this weapon. The crystallizing barrel modification remedies this issue by enabling the Cryolator to fire individual cryonic capsules. In addition to being more ammunition friendly, these capsules deal additional ballistic damage. Because it is a heavy weapon, the Cryolator therefore benefits from the Heavy Gunner perk.

  • The Cryolater is in the Master-locked case in the Vault 111 Overseer office. However, it can also be retrieved before obtaining the third rank of Locksmith by commanding Dogmeat to find nearby weapons, since he can bypass locked containers.
