Bugs

 * Friendly Fire is supposed to have a HUD notification Vault Boy popup, but it is flagged to be hidden.

 * Molotov cocktails are currently the only weapon which may apply the heal effect to NPCs. The thrown item must strike them prior to exploding; the fire hazard or explosion will not proc the effect.

Behind the scenes
Prior to Update 25, Friendly Fire could only be activated by swinging a shishkebab or bashing with a flamer.
