Basics
Damages
Health DamageDefinition The Health Damage is the amount of direct damage a bullet deals to a player's health pool at point-blank range (0 m). It is derived from the weapon's initSpeed, typicalSpeed, and possible damageOverride multipliers defined in the damageApplied block of the ammo's projectile. Formula General case: Where • = muzzle velocity from config (projectile) • = optional multiplier from the weapon (default = 1.0) • = reference speed defined in the ammo config • = damageOverride (per type or global); defaults to 1.0 if not present • = raw health damage from damageApplied → Health.damage Explanation The calculation ensures that ammo behaves consistently across different weapons. If a weapon fires the same bullet at a lower speed (for example, a revolver vs. a rifle), the effective health damage is reduced. Conversely, higher muzzle velocity increases the effective damage. The defaultDamageOverride and damageOverride entries allow fine-tuning per ammo type or damage... More

Shock DamageDefinition The Shock Damage is the amount of non-lethal trauma a projectile inflicts to the player's shock pool in DayZ. Unlike health or blood damage, shock directly affects the player’s consciousness. When the shock pool reaches zero, the character falls unconscious. Shock is determined by the ammo’s damageApplied → Shock.damage value and scaled by muzzle velocity, the ammo’s typicalSpeed, and optional damageOverride multipliers. Formula General case: Where • = muzzle velocity from the weapon’s config • = optional multiplier applied per weapon (default = 1.0) • = reference speed defined in the ammo config • = damageOverride (per type or global), defaults to 1.0 if not defined • = raw shock damage from damageApplied → Shock.damage Explanation Shock damage provides a balancing layer in combat: it can incapacitate players without instantly killing them. Small-caliber or non-lethal ammo may do little health damage but high shock, forcing unconsciousness rather than death.... More

Blood DamageDefinition The Blood Damage is the amount of damage a projectile inflicts to the player's blood pool in DayZ. It is derived from the ammo’s damageApplied → Blood.damage value and scaled according to muzzle velocity, the ammo’s typicalSpeed, and optional damageOverride multipliers. Blood damage is critical because excessive loss leads to unconsciousness or death, even if health remains high. Formula General case: Where • = muzzle velocity from the weapon’s config • = optional multiplier applied per weapon (default = 1.0) • = reference speed defined in the ammo config • = damageOverride (per type or global), defaults to 1.0 if not defined • = raw blood damage from damageApplied → Blood.damage Explanation This formula ensures consistency across weapons using the same ammo. A slower muzzle velocity reduces the effective blood damage (e.g., subsonic use or short barrels), while higher velocity increases it. The damageOverride values provide developers fine control...

Performance
Rate of FireDefinition: Rate of Fire (RPM) represents the maximum number of rounds a weapon can fire per minute in fully automatic mode (or the fastest firing mode available). It is a measure of how quickly the weapon can shoot, based on its internal reload cycle. Formula: Where: • reloadTime = the time (in seconds) it takes to chamber the next round in the current firing mode.

Shots before RuinedDefinition: Shots to Ruin is the estimated number of shots required to completely ruin a weapon’s barrel. It measures barrel endurance: higher values mean the barrel lasts longer before becoming unusable. Formula: Where: • hitpoints = base durability of the barrel (health points of the item)
• barrelArmor = protective factor of the barrel (resistance multiplier)
• damageBarrel = damage applied to the barrel per shot
Notes: • High values → the barrel can sustain more shots before being ruined.
• Low values → the barrel degrades quickly, leading to faster ruin.
• 0 → calculation is not applicable (e.g. if any variable is invalid or zero).

Ballistics
Projectile SpeedDefinition: Projectile Speed is the initial velocity of a bullet when fired, after accounting for any modifiers. It determines how fast the projectile travels immediately after leaving the barrel, directly influencing range, bullet drop, and hit registration. Formula: Where: • initSpeed = the base muzzle velocity defined in the weapon or ammo config (m/s)
• initSpeedMultiplier = a modifier applied by attachments, ammunition, or other factors

Supersonic Crack DistanceDefinition: Supersonic Crack Distance is how far a bullet travels before it slows down below the speed of sound (~340 m/s). While the bullet is supersonic, every shot produces a sharp crack that enemies can hear at long range. Once the projectile drops under 340 m/s, the crack disappears. • High values → the bullet stays supersonic longer (louder, heard further).
• Low values (close to 0) → the bullet goes subsonic quickly, reducing the audible crack.
• 0 → the bullet is subsonic from the start, no crack at all.
Formula: Where: • v0 = initial projectile speed (m/s)
• airFriction = bullet drag coefficient (negative value in DayZ configs)
• Low values (close to 0) → the bullet goes subsonic quickly, reducing the audible crack.
• 0 → the bullet is subsonic from the start, no crack at all.

Handling
Recoil ControlDefinition: The Recoil Modifier is a weapon property in DayZ that controls how much the weapon’s kick and stability are affected when firing. • It is stored as a vector (x y z) in the weapon’s config (recoilModifier). • Values are multiplicative per axis: • X, Y scale horizontal & vertical mouse recoil. • Z scales the camera effect. • Attachments with their own recoilModifier also multiply these values, creating a final per-axis recoil profile. • The game combines this with recoil patterns (mouseOffsetDistance, mouseOffsetMin, mouseOffsetMax) to generate the in-game kick and spread. Formulas: Where: • = base recoil modifier vector of the weapon • = recoil modifier of the i-th attachment Explanation: The recoil modifier works multiplicatively per axis. • A value of 1.0 = no change. • Values above 1.0 = stronger recoil. • Values below 1.0 = reduced recoil. Example: • Weapon recoil = (1.0, 1.0, 1.0)... More

Sway ControlDefinition The Sway Modifier is a weapon property in DayZ that defines how much a firearm's aim drifts on each axis while aiming. • It is stored as a vector (x y z) in the weapon’s config (swayModifier). • A value of 1.0 means no change (default sway). • Values above 1.0 increase sway (less control). • Values below 1.0 reduce sway (better stability). • When attachments are added (scopes, suppressors, handguards, etc.), their sway modifiers are multiplied per-axis with the weapon’s base sway. This system allows each weapon + attachment setup to feel unique in terms of stability. Formula The final sway modifier applied in-game is the multiplicative product per axis: • = base sway vector of the weapon • = sway modifier of the i-th attachment • Multiplication is done per axis (x, y, z) Scalar Reduction (for UI/Stats) To express sway as a single score instead of...

Damage ScoreDefinition The Damage Score is a synthetic stat in DayZ that measures the overall lethality of a projectile or weapon.
It combines three types of damage applied to the player: • Health damage (direct injury)
• Shock damage (unconsciousness potential)
The score is normalized on a 1–100 scale, where 100 = maximum effect within realistic gameplay ranges. Formulas: Where: • = base health damage dealt by the projectile
• = shock damage dealt by the projectile
Explanation: • Each damage type is scaled to a cap (200 for health, 150 for shock/blood).
• The scaling ensures that extreme values don’t push the score above 100.
• For the Damage Score, only Health and Shock are averaged, since these two define immediate incapacitation.
• Blood damage is exposed separately but not included in the final score.
Example: • Health = 120 → HealthScore=60HealthScore = 60HealthScore=60
• Shock = 150 → ShockScore=100ShockScore = 100ShockScore=100
Final Damage Score = (60+100)/2=80(60 + 100) / 2 = 80(60+100)/2=80. More

Ballistic ScoreDefinition The Ballistic Score is a synthetic stat in DayZ that measures the shooting efficiency of a projectile. It focuses on muzzle velocity, durability, and supersonic quietness. Additional ballistic properties such as rate of fire (RPM), penetration power, and damage retention are displayed separately but not included in the final score. The score is normalized on a 1–100 scale, where higher is better. Formula Speed Score (muzzle velocity): Higher projectile speed means flatter trajectory and better hit probability. Durability (Shots to Ruin): Represents how many rounds a weapon can fire before breaking. Supersonic Quietness: Measures how quiet the bullet’s supersonic crack is (lower crack = higher score). Final Ballistic Score: This averages speed, durability, and stealth (supersonic quietness) into a single efficiency score. Where • = muzzle velocity (m/s) • = number of shots before the weapon is ruined • = loudness of the bullet’s supersonic crack Explanation The Ballistic... More

Handling ScoreDefinition The Handling Score is a synthetic stat in DayZ that measures how easy a weapon is to control when aiming and shooting. It combines recoil control, sway stability, accuracy (dispersion), and rate of fire (RPM) into a single rating. The score is normalized on a 1–100 scale, where higher values mean better stability and easier handling. Formula Recoil Score: Represents how much the weapon’s recoil can be controlled (higher = better). Sway Score: Represents aiming stability (higher = steadier aim). Dispersion Score (accuracy): Lower dispersion means tighter bullet grouping and higher accuracy. A linear normalization is applied between 0.0003 (best case) and 0.01 (worst case). These bounds are based on typical dispersion values defined in DayZ weapon configs, where precision rifles usually reach ~0.0003 and less accurate firearms can reach up to ~0.01. RPM Score (rate of fire contribution): Although RPM primarily affects ballistic efficiency, it is also included... More

Overall ScoreDefinition The Overall Score is the final synthetic stat in DayZ that combines all key aspects of a weapon’s performance. It merges Damage Score (lethality), Ballistic Score (shooting efficiency), and Handling Score (stability and usability) into a single weighted value. This provides a global 1–100 rating to compare weapons at a glance. Formula Overall Score (weighted average): Each component is multiplied by its weight (w_p, w_s, w_t) to balance its influence, then summed into a single score. The result is rounded to two decimals. Where • = Damage Score (1–100) • = Ballistic Score (1–100) • = Handling Score (1–100) • (60% weight on Damage Score) • (25% weight on Ballistic Score) • (15% weight on Handling Score) Explanation The Overall Score provides a single synthetic value to quickly compare weapons.

Dispersion Score (accuracy): Lower dispersion means tighter bullet grouping and higher accuracy. A linear normalization is applied between 0.0003 (best case) and 0.01 (worst case). These bounds are based on typical dispersion values defined in DayZ weapon configs, where precision rifles usually reach ~0.0003 and less accurate firearms can reach up to ~0.01. RPM Score (rate of fire contribution): Although RPM primarily affects ballistic efficiency, it is also included... More

Overall ScoreDefinition The Overall Score is the final synthetic stat in DayZ that combines all key aspects of a weapon’s performance. It merges Damage Score (lethality), Ballistic Score (shooting efficiency), and Handling Score (stability and usability) into a single weighted value. This provides a global 1–100 rating to compare weapons at a glance. Formula Overall Score (weighted average): Each component is multiplied by its weight (w_p, w_s, w_t) to balance its influence, then summed into a single score. The result is rounded to two decimals. Where • = Damage Score (1–100) • = Ballistic Score (1–100) • = Handling Score (1–100) • (60% weight on Damage Score) • (25% weight on Ballistic Score) • (15% weight on Handling Score) Explanation The Overall Score provides a single synthetic value to quickly compare weapons. It reflects not only raw damage, but also ballistic performance and ease of handling, weighted according to their importance... More

Health DamageDefinition The Health Damage is the amount of direct damage a bullet deals to a player's health pool at point-blank range (0 m). It is derived from the weapon's initSpeed, typicalSpeed, and possible damageOverride multipliers defined in the damageApplied block of the ammo's projectile. Formula General case: Where • = muzzle velocity from config (projectile) • = optional multiplier from the weapon (default = 1.0) • = reference speed defined in the ammo config • = damageOverride (per type or global); defaults to 1.0 if not present • = raw health damage from damageApplied → Health.damage Explanation The calculation ensures that ammo behaves consistently across different weapons. If a weapon fires the same bullet at a lower speed (for example, a revolver vs. a rifle), the effective health damage is reduced. Conversely, higher muzzle velocity increases the effective damage. The defaultDamageOverride and damageOverride entries allow fine-tuning per ammo type or damage... More

Shock DamageDefinition The Shock Damage is the amount of non-lethal trauma a projectile inflicts to the player's shock pool in DayZ. Unlike health or blood damage, shock directly affects the player’s consciousness. When the shock pool reaches zero, the character falls unconscious. Shock is determined by the ammo’s damageApplied → Shock.damage value and scaled by muzzle velocity, the ammo’s typicalSpeed, and optional damageOverride multipliers. Formula General case: Where • = muzzle velocity from the weapon’s config • = optional multiplier applied per weapon (default = 1.0) • = reference speed defined in the ammo config • = damageOverride (per type or global), defaults to 1.0 if not defined • = raw shock damage from damageApplied → Shock.damage Explanation Shock damage provides a balancing layer in combat: it can incapacitate players without instantly killing them. Small-caliber or non-lethal ammo may do little health damage but high shock, forcing unconsciousness rather than death.... More

Blood DamageDefinition The Blood Damage is the amount of damage a projectile inflicts to the player's blood pool in DayZ. It is derived from the ammo’s damageApplied → Blood.damage value and scaled according to muzzle velocity, the ammo’s typicalSpeed, and optional damageOverride multipliers. Blood damage is critical because excessive loss leads to unconsciousness or death, even if health remains high. Formula General case: Where • = muzzle velocity from the weapon’s config • = optional multiplier applied per weapon (default = 1.0) • = reference speed defined in the ammo config • = damageOverride (per type or global), defaults to 1.0 if not defined • = raw blood damage from damageApplied → Blood.damage Explanation This formula ensures consistency across weapons using the same ammo. A slower muzzle velocity reduces the effective blood damage (e.g., subsonic use or short barrels), while higher velocity increases it. The damageOverride values provide developers fine control...

Projectile SpeedDefinition: Projectile Speed is the initial velocity of a bullet when fired, after accounting for any modifiers. It determines how fast the projectile travels immediately after leaving the barrel, directly influencing range, bullet drop, and hit registration. Formula: Where: • initSpeed = the base muzzle velocity defined in the weapon or ammo config (m/s)
• initSpeedMultiplier = a modifier applied by attachments, ammunition, or other factors

• initSpeedMultiplier = a modifier applied by attachments, ammunition, or other factors

Supersonic Crack DistanceDefinition: Supersonic Crack Distance is how far a bullet travels before it slows down below the speed of sound (~340 m/s). While the bullet is supersonic, every shot produces a sharp crack that enemies can hear at long range. Once the projectile drops under 340 m/s, the crack disappears. • High values → the bullet stays supersonic longer (louder, heard further).
• Low values (close to 0) → the bullet goes subsonic quickly, reducing the audible crack.
• 0 → the bullet is subsonic from the start, no crack at all.
Formula: Where: • v0 = initial projectile speed (m/s)
• airFriction = bullet drag coefficient (negative value in DayZ configs)
• Low values (close to 0) → the bullet goes subsonic quickly, reducing the audible crack.
• 0 → the bullet is subsonic from the start, no crack at all.
Formula: Where: • v0 = initial projectile speed (m/s)
• airFriction = bullet drag coefficient (negative value in DayZ configs)

Shots before RuinedDefinition: Shots to Ruin is the estimated number of shots required to completely ruin a weapon’s barrel. It measures barrel endurance: higher values mean the barrel lasts longer before becoming unusable. Formula: Where: • hitpoints = base durability of the barrel (health points of the item)
• barrelArmor = protective factor of the barrel (resistance multiplier)
• damageBarrel = damage applied to the barrel per shot
Notes: • High values → the barrel can sustain more shots before being ruined.
• Low values → the barrel degrades quickly, leading to faster ruin.
• 0 → calculation is not applicable (e.g. if any variable is invalid or zero).
• barrelArmor = protective factor of the barrel (resistance multiplier)
• damageBarrel = damage applied to the barrel per shot
Notes: • High values → the barrel can sustain more shots before being ruined.
• Low values → the barrel degrades quickly, leading to faster ruin.
• 0 → calculation is not applicable (e.g. if any variable is invalid or zero).

Damage ScoreDefinition The Damage Score is a synthetic stat in DayZ that measures the overall lethality of a projectile or weapon.
It combines three types of damage applied to the player: • Health damage (direct injury)
• Shock damage (unconsciousness potential)
The score is normalized on a 1–100 scale, where 100 = maximum effect within realistic gameplay ranges. Formulas: Where: • = base health damage dealt by the projectile
• = shock damage dealt by the projectile
Explanation: • Each damage type is scaled to a cap (200 for health, 150 for shock/blood).
• The scaling ensures that extreme values don’t push the score above 100.
• For the Damage Score, only Health and Shock are averaged, since these two define immediate incapacitation.
• Blood damage is exposed separately but not included in the final score.
Example: • Health = 120 → HealthScore=60HealthScore = 60HealthScore=60
• Shock = 150 → ShockScore=100ShockScore = 100ShockScore=100
Final Damage Score = (60+100)/2=80(60 + 100) / 2 = 80(60+100)/2=80. More

Ballistic ScoreDefinition The Ballistic Score is a synthetic stat in DayZ that measures the shooting efficiency of a projectile. It focuses on muzzle velocity, durability, and supersonic quietness. Additional ballistic properties such as rate of fire (RPM), penetration power, and damage retention are displayed separately but not included in the final score. The score is normalized on a 1–100 scale, where higher is better. Formula Speed Score (muzzle velocity): Higher projectile speed means flatter trajectory and better hit probability. Durability (Shots to Ruin): Represents how many rounds a weapon can fire before breaking. Supersonic Quietness: Measures how quiet the bullet’s supersonic crack is (lower crack = higher score). Final Ballistic Score: This averages speed, durability, and stealth (supersonic quietness) into a single efficiency score. Where • = muzzle velocity (m/s) • = number of shots before the weapon is ruined • = loudness of the bullet’s supersonic crack Explanation The Ballistic... More

Handling ScoreDefinition The Handling Score is a synthetic stat in DayZ that measures how easy a weapon is to control when aiming and shooting. It combines recoil control, sway stability, accuracy (dispersion), and rate of fire (RPM) into a single rating. The score is normalized on a 1–100 scale, where higher values mean better stability and easier handling. Formula Recoil Score: Represents how much the weapon’s recoil can be controlled (higher = better). Sway Score: Represents aiming stability (higher = steadier aim).
