This question acts as a followup to How is incoming damage calculated in Fallout 4?

I have the formula for how damage is calculated normally, but I am under the impression that at least ballistic weapons have a range modifier to damage, e.g. they do less damage at greater range.
What is the formula for this damage modification?

A weapon's range value is the maximum range within which a weapon does maximum damage. Exceeding it, the damage output will increasingly decrease until at twice the range and after, the damage output will be halved.

  • A weapon's 'Range' (which is likely in in-game meters or (more appropriately) feet) is the distance after which a projectile's speed (or damage) deteriorates, or, in the words of the Fandom page:

    the furthest distance that a particular weapon will deal its maximum damage outside of V.A.T.S. and additionally affect the chance to hit a target when using V.A.T.S.

    It can thus be interpreted as "maximum optimal range".

  • According to the Damage Resistance page on Fandom, weapon damage beyond this maximum range will decrease the damage up to 50% when the range is doubled:

    PaperDamage = WeaponBaseDamage x RangeMulti ( x Perk 1 × Perk 2 × ⋯)


    RangeMulti is 1.0 at 100% WeaponRange or closer, 0.5 at 200% of WeaponRange or farther, and scales from 1.0 to 0.5 as range increases from 100% to 200% of WeaponRange.

    This applies to projectile, close-combat, and energy weapons.
    From some point onward, the damage will drop to 0, but this is beyond the vanilla maximum NPC draw distance.

    EDIT: each weapon has an Out-of-Range Multiplier value. It is true that for most weapons this value is 0.5, but some weapons deviate from this (like the Assaultron Laser, which only decreases to 0.8).

  • The meter is the basic unit of distance in the International System of Units (SI), the world's standardized system of measurement. So no. Feet is not more appropriate.

  • @nr_aus Don't you think we might have different concepts of "appropriateness" in this context, a term that is quite subjective to begin with? The USA still mostly uses feet, and Fallout 4 is an American game. I think I wrote "more appropriately" because the in-game units correspond with feet rather than metres.

  • Your argument isn't with me, its with the International System of Units.

  • @nr_aus I don't have an argument: you told me "feet is not more appropriate", and I gave you a reason why it is more appropriate in this context. This is completely moot anyway.

From the ck, the range is range where the weapon can do the max damage.

Min: Distance in units where damage falloff begins. Max: Distance in units where damage falloff ends.

Units are in feets

When applying range mods to weapons, one can test it by going into V.A.T.S. and selecting settlers or turrets, turrets being the better choice due to being stationary; queued shots will indicate less damage once one is past the range limit.

Testing myself, Between the min and max range, the reduction is progressive from 100% to around 30%.
