Armor and Damage System
The Armor and Damage System is a core mechanic in Counter-Strike 2 that governs how damage is calculated, how armor reduces incoming damage, and how different body parts take different amounts of damage.
Overview
Damage in CS2 is determined by a combination of the weapon's base damage, the distance to the target, the body part hit, and whether the target is wearing armor. Understanding these mechanics helps players make informed decisions about weapon purchases, aim placement, and economic strategy.
Armor Types
Kevlar Vest ($650)
The Kevlar Vest protects the chest, stomach, and arms from damage. It reduces incoming bullet and grenade damage based on the weapon's armor penetration value. The vest also nearly eliminates aimpunch (screen shake when hit) for body shots.
Kevlar + Helmet ($1,000)
The Kevlar + Helmet adds head protection to the vest. The helmet is critically important because it prevents one-shot headshot kills from most weapons. Without a helmet, even an M4A4 can kill with a single headshot.
Note: If you already have a vest with 100 armor points, you can buy just the helmet upgrade for $350.
Weapons That Can One-Shot Through Helmet
| Weapon | Notes |
|---|---|
| AK-47 | One-shot headshot at all ranges |
| SG 553 | One-shot headshot at all ranges |
| Desert Eagle | One-shot headshot at close-medium range |
| AWP | One-shot kill to any body part (except legs) |
| SSG 08 | Only against unarmored opponents (headshot) |
| SCAR-20 / G3SG1 | One-shot headshot at most ranges |
How Damage Is Calculated
The damage formula in CS2 works as follows:
- Base damage is determined by the weapon
- Range modifier reduces damage over distance (each weapon has a different falloff)
- Hitbox multiplier is applied based on where the bullet hits
- Armor reduction is applied if the target has armor covering that hitbox
Hitbox Multipliers
| Hitbox | Multiplier |
|---|---|
| Head | 4x (most weapons) |
| Chest / Arms | 1x |
| Stomach | 1.25x |
| Legs | 0.75x |
Note: Leg shots are never reduced by armor, as armor does not protect the legs. However, the 0.75x multiplier means leg shots deal less base damage.
Armor Damage Reduction
When a bullet hits an armored hitbox, the damage is multiplied by the weapon's armor penetration percentage. For example:
- AK-47 base damage: 36, armor penetration: 77.5%
- Armored chest shot: 36 x 1.0 (chest) x 0.775 (armor) = 27 damage
- Unarmored chest shot: 36 x 1.0 = 36 damage
Armor Points
Armor starts at 100 points when purchased. Each hit that is absorbed by armor reduces the armor value. However, as long as armor points remain above 0, the full damage reduction applies. There is no difference between 100 armor and 1 armor in terms of protection.
Armor is typically damaged by approximately 2 points for every 1 point of damage absorbed. A player can go many rounds without needing to rebuy armor if they take limited damage.
Aimpunch
Aimpunch is the screen shake effect that occurs when a player takes damage. Armor dramatically reduces aimpunch:
- Without armor: Severe aimpunch that makes accurate shooting nearly impossible
- With vest: 95% reduction in aimpunch for body shots
- With helmet: Near-complete elimination of aimpunch for headshots
This is one of the primary reasons armor is considered essential on buy rounds.
Economic Considerations
- Kevlar Vest ($650) should be purchased on every buy round, even force buys.
- Helmet ($350 upgrade or $1,000 full) is essential against weapons that cannot one-shot headshot through helmet (like the M4A4 and M4A1-S).
- On CT side, if the enemy team is using only AK-47s and AWPs, some players skip the helmet since these weapons kill through helmet anyway, saving $350.
- On eco rounds, not buying armor allows faster economy recovery but significantly reduces survivability.
