FOBoSLogoThe following is based on Fallout: Brotherhood of Steel and has not been confirmed by canon sources.

Oh, the big boom itself. All the fury of nature in a small, convenient package. It's the definitive room clearer, which might include you unless you hightail it to safe distance before the Mini-Nuke detonates. Use it against huge foes.

The mini nuke grenade is an explosive thrown weapon from Fallout: Brotherhood of Steel.


This damage can instantly kill many creatures and seriously injuring those who are more resistant to damage. Its scope is very wide and the user will surely be touched by the explosion. Once hit by the explosion, people affected will be electrocuted for about ten seconds.

It's available in a single copy in the game.
