Better Criticals (Fallout 3)

Better Criticals is a perk $$

Effects
With this perk, the weapon's critical damage is increased by 50%. Due to the way in which the critical hits are determined, any weapon that produces multiple independent projectiles per shot will individually check each hit for a critical when firing outside of V.A.T.S. and result in the full bonus critical damage for each success.

Criticals are automatic in sneak mode, point blank sneak attacks with one of these weapons will inflict X times the critical damage rating of the weapon, where X is the number of individual projectiles fired.
