The cryo mine is a mine that in the Fallout 3 add-on Mothership Zeta.


The cryo mine deals a single point of damage to its target, but also freezes them solid for 3 seconds.


These mines can be obtained from Elliott Tercorien after releasing him from stasis and going through the cryo lab with him. He will pick up some cryogenic parts in the area where Beckett and Daniels are frozen which enables him to start making the mines upon return to the engineering core. He will give the Lone Wanderer three cryo grenades and three cryo mines after they wait an hour for him to make them. After that one must wait another 3 hours for him to make two more each time the Wanderer asks.


  • The cryo mine was originally a weapon cut from the final version of Fallout 3 for an unknown reason. It does not exist in the final version of the game, nor does it exist as an unused item in the G.E.C.K. editor. However, the mesh and texture are contained within Fallout 3's BSA files, these files however were not used and new meshes and textures were made to replace them in Mothership Zeta (the original mesh and texture were eventually used in Operation: Anchorage as spider drones). Another cryo weapon, the Cryolator, exists only as a mesh and textures in Fallout 3's BSA files.
  • Reverse pick-pocketing a cryo mine or a cryo grenade, then backing away from the non-player character will freeze the non-player character. While stunned one can pickpocket them at will without being caught.
  • Cryo mines and grenades may be requested after the quest "This Galaxy Ain't Big Enough..." but only if one exits the Decompression chamber at the end of the Spacewalk, opens the portal so their team can come through, and then uses the portal to immediately go back to the Engineering Core. The team will follow and Elliott will again be able to make them.

However, regardless of time waited and number of times he is asked, he may never complete them. If this happens the only way to revert to a previous save. [verified]
