Gun Spread Formula (Fallout: New Vegas) on GECKwiki.Fallout 4 is a post-apocalyptic RPG with a ton of weapons.
Prior to patch 1.4.0.525, ammunition that had a spread modification effect (like the 12 gauge shotgun shell) applied it to the aim spread instead of the weapon spread. The weapon condition has no effect on the weapon spread. Weapon spread is equal to the Min Spread stat of the weapon in degrees.
ArmPenalty is 0 with no crippled arms, 0.5 when the right arm is crippled with a one-handed weapon, 0.25 with one arm crippled with two-handed weapon, 0.5 when both arms are crippled with two-handed weapons. (multiplier: from 0.5 to 0)ĭamage to limbs increases (pre-perk) spread. The appropriate skill ( Guns, Energy Weapons or Explosives) reduces spread by 0.5% (from 50% up to 100%) per skill point. These combine additively, but by default, Weapon Condition is always 0, so only the Skill Effect matters if the appropriate game settings are tweaked, weapon condition (from 0 to 100%) times a constant will combine additively with skill. Mobility effects are additive, but under the game's default settings, they always sum to 1, and hence simplify out to being ignored if the appropriate game settings are tweaked, they can be used to apply different penalties across walking, running and remaining still. Accordingly, doing both reduces spread by 79%. Using Aim down sights reduces spread by 65%.
The exceptions being weapons with 0 spread. Therefore, no matter how skilled you are with the weapon or what perks you have, your weapon will always have a slight amount of spread. The total spread is the largest of the aim spread value due to the character aiming and the weapon spread value due to the weapon itself.
