Cryo Grenade (Mothership Zeta)

The Cryo Grenade is a new type of grenade which is added to Fallout 3 in the Mothership Zeta add-on.

Characteristics
It will freeze a target for a short time.

Obtaining
These grenades can be obtained from Elliot 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 grenades upon return to the Engineering Core. He will give you 3 Cryo Grenades and 3 Cryo Mines after you wait an hour for him to make them. After that must wait another 3 hours for him to make 2 more each time you ask.

If you talk to Toshiro Kago directly after obtaining 2 Cryo Grenades and Cryo Mines from Elliot Tercorien you also get these items from Toshiro. (360 confirmed)

After the quest "This Galaxy Aint Big Enough..." Elliot seems to lose the ability to create Cryo Grenades and Mines for the player.

Appearances
The appears in the Mothership Zeta add-on for Fallout 3.

The meshes and textures for the Cryo Grenade can be found in the BSA files for Fallout 3, suggesting it was cut from the retail version of the game, and Mothership Zeta appears to simply implement the existing files. Another cryo weapon, the Cryolator exists only as a mesh and textures in Fallout 3's BSA files.
