The common 18x value is not a universal GTA Online headshot multiplier. It comes from a game-file field keyed to the victim context. GTA Online player-versus-player damage uses a separate weapon value named NetworkHeadShotPlayerDamageModifier, and that value differs between weapons.
The number 18 is real. The mistaken part is applying it to every target and mode, then multiplying every weapon's GTA Online PvP damage by 18.
The short answer
GTA V weapon files contain more than one headshot modifier:
GTATracker field | Extracted game-file field | What it is used to represent |
|---|---|---|
|
| The player-victim context used by the Story Mode weapon data |
|
| The weapon's GTA Online player-versus-player headshot modifier |
Many weapons carry 18 in HeadShotDamageModifierPlayer. That does not mean the same weapon deals 18 times its body damage to another GTA Online player. In the current extracted data, the Carbine Rifle has a PvP value of 1.7, the SMG has 2.5, and the Pump Shotgun and Heavy Sniper each have 1.0.
Where the GTA 5 18x headshot claim comes from
The confusion begins with a plausible-looking field name. A parser can extract HeadShotDamageModifierPlayer, shorten it to “headshot multiplier,” and display 18 without retaining who “Player” identifies in that context.
GTATracker previously did that. A later audit separated the victim and mode contexts and added the network PvP value as its own field. The correction matters because the old label turned a valid number into a false universal rule.
The current pipeline preserves both fields:
- The versioned weapon file supplies base damage, fire rate, pellets, and both headshot modifiers.
- The importer maps
HeadShotDamageModifierPlayertoheadshot. - It maps
NetworkHeadShotPlayerDamageModifiertopvpHeadshotMult. - Derived-stat tests calculate shots to kill and time to kill from the appropriate PvP value.
This interpretation follows the field names and the correction audit. It is not a claim that every headshot outcome in every GTA V script can be reduced to one multiplication.
GTA Online PvP headshot multipliers by weapon
The table below uses a 100-health and a 200-health target as clean comparison points. It ignores armour, range falloff, special ammunition, and other modifiers.
Weapon | Base damage | PvP headshot multiplier | Body shots at 100 / 200 | Headshots at 100 / 200 |
|---|---|---|---|---|
32 | 1.7x | 4 / 7 | 2 / 4 | |
22 | 2.5x | 5 / 10 | 2 / 4 | |
29 × 8 pellets | 1.0x | 1 / 1* | 1 / 1* | |
216 | 1.0x | 1 / 1 | 1 / 1 |
Carbine Rifle
SMG
Pump Shotgun
Heavy Sniper* The Pump Shotgun result assumes all eight pellets land at a range where the full 29 damage per pellet applies. A partial spread or falloff changes the result.
The values show why “all headshots are 18x” cannot describe PvP. The SMG's 2.5x network modifier is different from the Carbine Rifle's 1.7x. A 1.0 value does not make a weapon weak. The Heavy Sniper already crosses both example health thresholds with its base 216 damage.
How shots to kill and time to kill are calculated
Shots to kill is the target health divided by damage per shot, rounded up:
STK = ceiling(target health ÷ damage per shot)
For a PvP headshot in this simplified model:
headshot damage = base damage × pvp headshot multiplier
For an automatic weapon, time to kill starts at zero when the first bullet lands:
TTK = (shots to kill - 1) × 60 ÷ rounds per minute
The subtraction is important. Four bullets create three intervals between hits, not four.
Carbine Rifle example
The extracted Carbine Rifle inputs are 32 base damage, 444 rounds per minute, and a 1.7x PvP headshot multiplier.
Body shots against 100 health:
ceiling(100 ÷ 32) = 4 shots(4 - 1) × 60 ÷ 444 = 0.405 seconds
Headshots against 100 health:
- Head damage is
32 × 1.7 = 54.4 ceiling(100 ÷ 54.4) = 2 shots(2 - 1) × 60 ÷ 444 = 0.135 seconds
Against 200 health, the same simplified calculation gives seven body shots in 0.811 seconds or four headshots in 0.405 seconds.
This is a derived mathematical result from the extracted inputs. It is not a recorded network-match benchmark.
SMG example
The SMG has 22 base damage, 508 rounds per minute, and a 2.5x PvP headshot multiplier. Its calculated headshot damage is 55.
Against 100 health, it takes five body shots or two headshots. The corresponding times are 0.472 and 0.118 seconds. Against 200 health, it takes ten body shots in 1.063 seconds or four headshots in 0.354 seconds.
The SMG and Carbine Rifle both need two simplified headshots at 100 health, even though their base damage and multipliers differ. Shots-to-kill thresholds can hide a numerical damage difference until health, armour, or range changes.
Pump Shotgun example
The Pump Shotgun stores 29 damage per pellet and eight pellets, with a 1.0 PvP headshot multiplier. A full point-blank connection therefore has a theoretical raw total of:
29 × 8 = 232 damage
That crosses both the 100 and 200 example thresholds in one shot. The result depends on all pellets landing before falloff or other rules reduce the applied damage. Treating 29 as the whole shell would be wrong, but treating 232 as guaranteed at every range would also be wrong.
The 1.0 PvP headshot value means this simplified network field does not add a head multiplier for the weapon. It does not prove that every shotgun interaction, pellet location, script, or mode behaves identically.
Heavy Sniper example
The Heavy Sniper stores 216 base damage and a 1.0 PvP headshot multiplier. Base damage alone clears both example thresholds, so body and head calculations each return one shot at 100 or 200 health.
This shows why multiplier size cannot be read as a weapon ranking. A large multiplier can compensate for low base damage. A 1.0 multiplier can sit on top of damage that already crosses the target threshold.
Why the Ammu-Nation stat bars do not settle the question
The in-game damage, fire rate, accuracy, and range bars are presentation values. They are useful for a rough comparison but are not direct displays of the extracted damage number, pellet count, network headshot modifier, or range curve.
A weapon with a longer damage bar does not tell you its exact PvP shots to kill. Use the GTA 5 weapon database for versioned fields and the comparison tool to put the inputs side by side.
What this calculation does not include
The examples intentionally isolate base damage and the network PvP headshot field. A live outcome can also depend on:
- target health and armour
- distance and damage falloff
- pellet spread and how many pellets connect
- ammunition type and weapon modifications
- mode or mission scripts
- network state and hit registration
- NPC-specific headshot behaviour
The extracted files also contain an AI-victim headshot context. GTATracker does not currently present that as a single universal NPC promise because scripted and target-specific behaviour can matter. A value in a data file is an input to the game, not proof that every encounter exposes it without other rules.
