Nuka-Grenade

The Nuka Grenade is similar to the mini nuke fired from the Fat Man in many ways, although smaller and lighter. The grenade is found in higher levels on corpses and various loot and can also be created using Nuka-cola Quantum, Tin can, turpentine, and the name detergent(someone please edit if im wrong/you have more details). When thrown, the grenade explodes on impact and produces a high powered nuclear explosion (though not as high powered as the Fatman's explosion)

Appearances
Nuka Grenades appear only in Fallout 3.
