Have you ever emptied an entire MP40 magazine into an enemy’s chest, seen a dozen yellow numbers pop up, and watched in horror as they turned around and killed you with two shots? You scream “Hacker!” or “Fake Damage!”
But 99% of the time, it isn’t a hack. It isn’t lag. It is Math.
Free Fire is an RPG hidden inside a Battle Royale. It has complex damage formulas involving vest durability, armor penetration percentages, damage drop-off over distance, and limb damage multipliers. If you don’t understand these numbers, you are playing blind. You are picking the wrong guns for the wrong fights.
This guide is not a “Tips and Tricks” list. This is a scientific breakdown of how damage works in Free Fire 2026. By the end of this article, you will know exactly why the UMP beats the MP40 in late-game, and why Hayato is the most broken character for 1v1s.
1. The “Vest Reduction” Formula (Why your MP40 fails)
The most important mechanic in the game is Damage Reduction. When you pick up a vest, it doesn’t just give you extra HP; it reduces the incoming damage by a fixed percentage.
Here is the raw data for Vests in 2026:
| Armor Type | Damage Reduction % | Durability (HP) |
|---|---|---|
| Level 1 Vest | 33% | 190 |
| Level 2 Vest | 50% | 225 |
| Level 3 Vest | 66% | 260 |
| Level 4 Vest | 70% | 290 |
The Math in Action:
Let’s take the MP40 It has a base damage of roughly 25 per bullet
- Enemy with No Vest: You hit for 25 damage It takes 8 bullets to kill (200 HP)
- Enemy with Level 3 Vest (66% reduction): You hit for 8 damage. (25 – 66% = 8.5)
- Bullets to Kill: 200 HP / 8 damage = 25 bullets
You need to hit TWENTY FIVE bullets to kill someone with a Level 3 Vest using a base MP40.
Considering recoil and missed shots a standard 30 round magazine is often not enough to kill one person This is why you feel like your gun is shooting peas.
2. Armor Penetration (The “God Stat”)
This is where the game changes. Armor Penetration (AP) is a stat that allows a percentage of your damage to ignore the vest’s reduction.
If a gun has 50% Armor Penetration (like the UMP or Woodpecker), it means 50% of the enemy’s vest level is ignored.
The UMP Example (vs Level 3 Vest):
- Base Damage: 25
- Armor Pen: 65% (High)
- Calculation: Instead of the vest blocking 66% of damage, the UMP forces the vest to act like a Level 1 vest
- Result: You hit for 16-18 damage per bullet instead of 8
- Bullets to Kill: 12 bullets
Conclusion: The UMP kills twice as fast as the MP40 against high level armor, even though the MP40 shoots faster In the late game (where everyone has Level 3/4 vests), Armor Penetration is infinitely more valuable than Fire Rate

3. The “Hayato” Factor (Why he is S-Tier)
Hayato’s skill Bushido grants Armor Penetration when your HP decreases. At Max Level (Awakened) for every 10% HP you lose your Armor Penetration increases by 5%
The “Clutch” Math:
Imagine you are fighting an enemy face-to-face You both start shooting
- At 200 HP: Your shots deal normal damage
- At 100 HP (50% health): You gain +25% Armor Penetration
- At 20 HP (10% health): You gain +45% Armor Penetration
This means the more damage you take, the harder you hit. In the last second of a fight, your bullets basically ignore their vest completely A shotgun shot that normally does 15 damage might suddenly do 40 damage per pellet
This allows you to win “impossible” fights where you have 1 HP left
4. Range Drop-off (The Silent Killer)
Another reason you see yellow numbers but no kill is Range. Every gun has an “Effective Range” Beyond this range, damage drops drastically.
The Shotgun Problem
Shotguns (M1887/M1014) have very short range
- 0-5 Meters: 100% Damage
- 6-10 Meters: 40% Damage
- 10+ Meters: 5-10% Damage
If you shoot an M1887 at an enemy 12 meters away, you might see hitmarkers but you are dealing 2 damage per pellet You are tickling them. You must know your weapon’s effective distance
The SMG vs AR Debate
SMGs lose damage faster than ARs. At 30 meters:
- SCAR (AR): Deals 25 damage (Full damage)
- MP40 (SMG): Deals 12 damage (Drop-off)
This is why you should never challenge an AR player with an SMG in an open field. Even if your aim is better, their math is better

5. Limb Damage vs Chest Damage
Where you hit matters. Free Fire divides the body into hitboxes with multipliers
- Head: 4.0x to 5.5x Damage (Instant Kill)
- Chest/Torso: 1.0x Damage (Base)
- Arms/Legs: 0.75x or 0.6x Damage
The Mistake: Many players aim too low If you hit the enemy’s legs, your damage is reduced by nearly 40% An AWM shot to the chest does 150 damage An AWM shot to the leg does 70-80 damage. That is the difference between a knock and a survival
Tip: Always keep your crosshair at Chest Level or Head Level. Never look at the ground while running
6. The Character “Counter-Math”
Certain characters exist solely to break these damage rules You need to know them
Wolfrahh (The Headshot Tank)
Wolfrahh reduces damage taken from headshots by up to 30% (based on spectators/kills) If you shoot a Wolfrahh user in the head it might NOT kill them instantly A Kar98k headshot that usually deals 300 might only deal 190 They survive with 10 HP and kill you
Andrew “The Fierce” (The Vest Buffer)
Awakened Andrew increases vest durability loss reduction AND reduces damage taken to armor If a full squad runs Andrew, their vests become incredibly tanky.
Explosives and snipers are less effective against them.
Justin Bieber (J.Biebs)
He blocks 15% of damage using EP. If the enemy has full EP (from K or Mushrooms), they effectively have 230 HP instead of 200 HP. That extra 15% blockage can survive an extra M1887 shot.
7. Scenario Analysis: Which Gun Wins?
Let’s simulate a fight based on math.
Scenario: Inside a House (3 Meters)
Player A: MP40 (High Rate of Fire, Low AP).
Player B: M1887 (High Burst, Mid AP).
Winner: M1887. Why? Because at 3 meters, the M1887 lands all pellets instantly. The “Alpha Damage” (damage delivered in 0.1 seconds) is higher than the MP40’s need to ramp up over 1 second. Burst beats Spray in ultra-close range.
Scenario: Open Field (20 Meters)
Player A: UMP (High AP).
Player B: M1887.
Winner: UMP. Why? At 20 meters, M1887 damage drops to near zero. The UMP maintains damage and shreds the vest.
Conclusion: The “Knowledge Gap”
Free Fire is not just about moving your fingers fast. It’s about knowing that an MP40 is useless against a Level 4 Vest unless you hit headshots. It’s about knowing that Hayato gives you a mathematical advantage when you are losing a fight.
The Final Rule: Prioritize Armor Penetration over Rate of Fire in the late game. Use the UMP, Woodpecker, M1887, or AC80. Leave the MP40 for the early game when enemies have no vests.
Frequently Asked Questions (FAQ)
Q: Does the “Damage” stat on gun skins matter?
A: Yes. A “+” in Damage increases base damage. A “++” is a significant boost. However, “++ Rate of Fire” is usually superior for Drag Headshots because more bullets = more chances to hit the head.
Q: How do I know if I have Armor Penetration?
A: Check the weapon stats in the Armory. Also, when you shoot, if you see a “broken shield” icon next to the damage numbers, that indicates Armor Penetration is taking effect.
Q: Is the Helmet Level 4 indestructible?
A: No. A Sniper or Shotgun headshot will still one-tap a Level 4 Helmet. However, it might save you from SMG spray headshots.
