Cryo Mine (Mothership Zeta)

The  was 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.

From its name and appearance, we can infer that this weapon would have been to the Cryo Grenade what the Frag Mine is to the Frag Grenade. The Cryo Grenade was also originally cut from Fallout 3, but will be added to the game in the Mothership Zeta add-on.
