How CS 1.6 Damage & Hitboxes Work

Understanding hitbox multipliers is the single biggest skill jump between a casual CS 1.6 player and a competitive one. The game doesn't apply a flat damage number — every bullet is scaled by where it lands on the enemy model.

The six hitboxes

Every player model has six damage regions:

Hitbox	Damage multiplier	Notes
Head	×4.0	The reason "aim high" wins rounds
Chest	×1.0	Baseline
Stomach	×1.25	Higher than chest — aim for the belt line
Left arm	×1.0	Same as chest
Right arm	×1.0	Same as chest
Legs (each)	×0.75	Lowest multiplier — avoid

These are the CS 1.6 values. CS:S and CS:GO shifted the numbers slightly, so don't cross-reference from newer game guides.

What "×4.0" actually means

Take the AK-47. Base chest damage is 36. Apply the multipliers:

Chest: 36 × 1.0 = 36
Stomach: 36 × 1.25 = 45
Leg: 36 × 0.75 = 27
Head: 36 × 4.0 = 144 — one-shot kill (players start with 100 HP)

That's why the AK is called a one-shot-headshot rifle. The M4A1 has base 33 → 132 headshot, also a one-shot on unhelmeted enemies.

Armor mechanics

Kevlar changes the arithmetic entirely.

Kevlar (body armor)

Absorbs a portion of body damage (chest, stomach, arms, legs).
Damage passed to health is roughly halved, and the vest loses points based on the weapon's armor penetration rating.
Once armor hits 0, all damage passes to health.

Helmet

Only bought together with kevlar ("kevlar + helmet" in the buy menu).
Blocks or reduces damage from headshots specifically.
Against most pistols and SMGs, a helmet can turn a one-shot headshot into a survivable hit.
Against the AK-47, AWP, Scout, Deagle and a few others, the helmet is not enough — you still die in one head-hit.

One-shot-headshot chart (vs Kevlar + Helmet)

Weapons that kill in one head-hit even against a helmeted target (at combat distance, no falloff):

Weapon	One-shot vs helmet?
AWP	Yes — any hitbox above the knee
AK-47	Yes
SG 552	Yes
G3SG1	Yes
SG 550	Yes
Scout	Yes (head only)
Deagle	Yes (head only, close range)
M4A1	No — requires 2 head-hits vs helmet
AUG	No
FAMAS	No
Galil	No
MP5 / P90 / UMP	No

That table is why "one-tap potential" is the single most-cited stat when players argue about which rifle is better.

Distance falloff

Bullet damage in CS 1.6 falls off with distance, but slower than in modern shooters. A rifle at 40 metres still hits for close to its base value. Pistols and SMGs fall off much faster — a Glock at 30 metres feels like a peashooter.

The AWP has no meaningful damage falloff at any playable range. If it hits, it hits full.

Wall penetration

CS 1.6 uses per-weapon penetration ratings that let bullets pass through walls, doors and crates with reduced damage. Rough tiers:

High penetration: AWP, AK-47, G3SG1, SG 550, M4A1, SG 552, AUG, M249, Deagle. These will kill through most single-thickness walls.
Medium: MP5, UMP, P90, FAMAS, Galil.
Low / none: shotguns, pistols (except Deagle), grenades.

The classic use is spamming through the wooden garage door on de_train, the crates on de_nuke, or the sheetrock walls on de_dust2 mid.

Damage in numbers (rifle base chest damage)

Weapon	Base chest damage
AWP	~115 (any body shot = instant kill vs armored)
G3SG1	80
SG 550	70
Deagle	54
AK-47	36
SG 552	33
M4A1	33
Galil	30
AUG	32
FAMAS	30
Scout	75 (one-shot upper body, 2 shots leg)

Numbers vary very slightly between community documentation sources (community docs like the Counter-Strike Wiki reference weapons.res game files); the table above is the values you can verify by test-shooting bots in a private server.

What this means for aim

Three practical rules:

Aim head-height by default. Even if you miss high, the ×4 multiplier means a chest shot lands as a chest shot, not a leg shot.
Never spray legs. ×0.75 is a punishing multiplier — you'll pump 4-5 bullets into someone and they'll turn and one-tap you.
Stomach is a valid aim point at range. ×1.25 beats chest, so if the head is bobbing, aim at the belt buckle.
