Ninja

Ninja is a Fallout 3 and Fallout:New Vegas Perk.

The Ninja perk grants you the power of the fabled shadow warriors. When attacking you gain a +15% critical chance on every strike, only with either Melee or Unarmed. Sneak attack criticals do 25% more damage than normal. This perk is more suitable for players who follow a "ninja" play style, similarly to Grim Reaper's Sprint, which is suitable for players who follow play styles that use V.A.T.S. more often.
