Gun Fu is a perk in Fallout 4, Fallout 76 and Fallout: The Roleplaying Game.


Fallout 4

Rank Requirements Description Form ID
1 AGI 10 You've learned to apply ancient martial arts to gunplay! Do 25% more damage to your second V.A.T.S. target and beyond. 0004D881
2 AGI 10, LVL 26 In V.A.T.S. you do 50% more damage to your third target and beyond. 001D244F
3 AGI 10, LVL 50 In V.A.T.S. you instantly do a Critical Hit against your fourth target and beyond. 001D245C

This perk causes each shot on targets after the initial target to do additional damage, but only applies to a new target in V.A.T.S. Additional shots at the first target do not count towards the chain. At rank 3, every target from the fourth and beyond will be an automatic critical hit. The effect only applies to additional targets, not additional limbs within the same target, and queueing actions "back and forth" across two or more targets does not trigger the effect on the first target.

V.A.T.S. allows only 16 actions to be queued, potentially allowing for 13 critical hits to be delivered. These critical hits do not count towards refilling the critical meter, however.

Settlement turrets and grenades/mines (enemy or player character thrown) count towards targets in the chain.

This perk stacks very well with the Better Criticals perk, as well as the Penetrator perk.

Fallout 76

Rank Description Form ID
1 V.A.T.S. swaps targets on kill with +10% damage to your next target 0004D881
2 V.A.T.S. swaps targets on kill with +10% then 20% damage to your next 2 targets 001D244F
3 V.A.T.S. swaps targets on kill with +10%, 20%, then 30% damage to your next 3 targets 001D245C

Fallout: The Roleplaying Game

When succeeding at a ranged attack, may spend 1 AP and 1 ammo to hit a second target within Close range of your initial target. The second target takes the same damage as the initial target.

At rank 2, may spend 2 AP and 2 ammo to hit two additional targets. At rank 3, you may spend 3 AP and 3 ammo to hit three additional targets.

This perk only applies the damage to additional targets, such as the vicious effect but ignores effects such as piercing and burst.[1]

Each time this perk is taken, the level requirement increases by 5.


Rank Level req. Additional targets
1 Level 1 1
2 Level 6 2
3 Level 11 3


While the additional damage of a critical hit is typically inconsequential by the time Rank 3 of the perk can be taken, the more important aspect of the perk is that (other than when using a weapon with the Two Shot modification) a critical shot always hits, regardless of how low the percentage shown in V.A.T.S. is, and this applies to criticals caused by this perk as well.

Behind the scenes

The name of the perk is a pun on the fighting style Kung fu. Gun fu, also known as gun kata, is a real-world concept for a formalized set of choreographed movements based on martial arts and optimized for close quarters gun fighting. The style was popularized in some Hong Kong and American films, particularly near-future dystopian movies like Equilibrium.
