Splash Damage

 is a perk in Fallout: New Vegas.

Effects
When you're deep in enemy territory, you just start chucking grenades and hope for the best. All Explosives have a 25% larger area of effect when they detonate.

Note: it seems to greatly increase all Explosive weapons splash, visually and physically, this also means the almighty Fat Man is affected by this as the small nuclear blast is greatly increased visually and physically meaning this: shoot farther if you wish to avoid your own death or injury from the blast! this perk is greatly needed if you wish to clear rooms or buildings with the Fat Man (as this perk MIGHT be focused on buffing the weapon, along with demolitions Expert Perk)
