Weapons Spread determines the accuracy of a ranged weapon in degrees. Formulas here taken from the GECK wiki.
The total spread is equal to a spread due to the character aiming, and a spread due to the weapon itself.
State effects combine multiplicatively.
- Crouching reduces spread by 40%. (multiplier: 0.6)
- Using iron sights reduces spread by 65%. (multiplier: 0.35)
Limb Condition EffectEdit
Damage to limbs increases (pre-perk) spread.
- ArmPenalty is 0 with no crippled arms. 0.5 when right arm crippled with one handed weapon, 0.25 when one arm crippled with two-handed weapon, 0.5 when both arms crippled with two-handed weapon.
Weapon spread is equal to the Min Spread stat of the weapon in degrees. Weapon condition has no effect on spread.
Fallout: New Vegas Prior to patch 220.127.116.115 ammunition that had spread modification effect (like 12ga), applied it to aim spread instead of weapon spread.
