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 injure those who have heavy resistance to damage. Its effective range is very wide, and the user will surely be touched by the explosion when used. Once hit by the explosion, people affected will be electrocuted for roughly ten seconds.

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