Cryolator (Fallout 3)

The Cryolator is a weapon cut from the final version of Fallout 3 and is in Fallout 4

Characteristics

Fallout 3

Several junk items possibly related to the Cryolator were also cut from Fallout 3; a coolant component (which forms the midsection of the Cryolator) and a liquid nitrogen canister (which was possibly intended as ammunition) are two. Both of these items use the same texture file as the Cryolator.

Fallout 4

The Sole Survivor first finds the Cryolator behind a master lock case in Vault 111.
