Damage (EU2012)
Damage System
- Regarding the different numbers seen in the Armory info and the actual game values, it seems that the Base Damage range can vary, i.e. a weapon listed with a 9 damage can vary between 8 and 10 and you see the Maximum Damage listed onscreen during the game before firing.
- If the shot is a hit the game will then check to see its Critical Chance.
- If the Critical Chance roll is successful, the game will then calculate the Critical Damage.
- In addition, there are also specific Class perks that can increase Damage (both Base and Crit), such as:
- Headshot (Sniper) +2/4/6 Damage to Sniper Rifle, depending on weapon tech value
- Gunslinger (Sniper) +2 Damage to pistols
- Shredder (Heavy) +33% damage from all sources to the target
- HEAT Ammo (Heavy) +100% damage against robotic enemies
- Mayhem (Heavy) +1 to +3, depending on the weapon tech level
- Bring 'Em On +1 to +5 bonus, depending on the number of enemies
- Killer Instinct +50% Critical Damage
- Damage is rounded down.
- For example rocket to shredded target will do 6*1.33=7.98 -> 7 damage, and Mindfray to stimmed target will do 5*0.5 = 2.5 -> 2 damage.
- There seems to be a Damage cap (at least for explosives) - Rocket Launchers will deal 16 max damage using HEAT and Mayhem, regardless of using Shredder rockets or not.
Critical Damage
The game code that calculates Critical Damage is:
if(bCritical)
{
iDamage += 1;
iDamage = int(float(iDamage) * 1.50);
iDamage += class'XComEngine'.static.SyncRand(3, string(Name) @ string(GetStateName()) @ string(GetFuncName())) - 1;
return iDamage;
}
- Critical Damage is simply calculated by increasing the iDamage (Base Damage) roll by a factor of 1.5 before applying the bonuses/penalties from abilities/perks.
- The range for the actual iDamage seems to be a random roll with a range of -1 to apparently the integer that precedes the Critical Damage value. Thus, Base Damage from an Assault Rifle can vary between 3 and 4 while with a Plasma Sniper Rifle it can vary between 8 and 12.

- Damage can vary between -1 and +1 of the value listed on the Armory. Maximum damage is listed during missions.
- The results for the other perks can be deduced from this table by calculating the corresponding additions, i.e. Gunslinger will add +2 to Pistol iDamage, Bring 'Em On will also add a variable number, while Shredder will add 33% to the end Damage value.
- Headshot adds +2/4/6 damage to Sniper Rifle shots, depending on its tech level.
Confirmed Game Values
- Pistol: 3 crit (no extra damage perks)
- Plasma Pistol: 9 crit (Sniper, Gunslinger, all Pistol upgrades)
- Sniper Rifle: 10 crit (Headshot)
- Plasma Sniper Rifle: 20 crit (Headshot)
- Rocket Launcher: 16 (HEAT Ammo + Mayhem vs Sectopod/Cyberdisc/Drone) = max Rocket damage (tried it twice with and without Shredder Rocket, both times got the same 16 Damage result)
Weapons Kill Table
- Based on the above model, the tables below indicate how many shots (Base or Critical) are usually required to take down the aliens.
- BASE = alien can be killed with 1 shot dealing average (non-critical) damage
- CRIT = alien requires either 2 base shots or 1 critical hit with close to maximum critical damage.
