|For the statistic which influences hand-to-hand combat in Fallout, Fallout 2 and Fallout Tactics, see Melee Damage.|
Unarmed damage is a derived statistic in Fallout 3 and Fallout: New Vegas.
Fallout 3 & Fallout: New Vegas
Unarmed damage affects only damage done with unarmed weapons and fists. This damage is added to the damage value of unarmed weapons, in the case of using fists this is the only damage inflicted on a opponent.
For Melee weapons there is a separate statistic called Melee Damage. Strength does not influence Unarmed damage, it only influences melee damage.
Unarmed damage is governed directly by the Unarmed skill.
Example: A Unarmed skill of 100.
