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 a bottle of Nuka-Cola Quantum, a Tin can, Turpentine, Abraxo Cleaner and the proper Schematics.

When thrown, the grenade explodes on impact and produces a high powered nuclear explosion (though not as high powered as the Fatman's explosion.) Schematics for the Nuka Grenade can be acquired from the traveling caravan trader Doc Hoff.

Schematics have multiple copies located throughout the Capitol Wastelands allowing you to make better versions of the self-created weapons. Each copy you find past the first one allows you to make a better version (ie; Rock-It Launcher V2). So its a good idea to hunt down subsequent copies if you plan on using them often.

Multiple schematics will increase the effectiveness of the Nuka Grenade design and productivity. For example: after finding a second schematic, the items required to make only one grenade, now creates two. Two for the price of one.

Appearances
Nuka Grenades appear only in Fallout 3.

Other locations acquired
The Nuka Grenade schematics can be obtained for free by traveling South of Vault 101 to Cliffside Cavern. There is an adjoining cavern known as Yao Guai cave where you can locate the schematic at the end on a pile of bones.
