In Arena Breakout: Infinite, raw gun stats like recoil and ergonomics mean very little if your ammunition cannot pierce your opponent’s body armor. The game’s ballistics engine pits bullet penetration tiers (Level 1 to Level 6) against armor materials ranging from ultra-durable Aramid to brittle Ceramic plates.
Static ammo charts only provide baseline numbers, failing to calculate what happens during an active firefight as armor health degrades shot by shot. Using a dedicated Arena Breakout Infinite Ammo Calculator and ABI Shots to Kill Calculator gives you exact, dynamic ballistics simulations to master your time-to-kill (TTK) before deploying into high-stakes raids.
How Armor Penetration & Material Degradation Work
Every round fired in Arena Breakout: Infinite triggers two simultaneous ballistic checks: whether the bullet punches through the plate to deal full flesh damage, and how many points of durability are stripped from the armor.
The Core Ballistics Formulas
$$\text{Armor Durability Damage } (\Delta D) = \text{Bullet Armor Damage} \times \text{Material Modifier}$$$$\text{Penetration Probability } (P_{\text{pen}}) = f(\text{Bullet Pen Level} - \text{Armor Tier}, \text{Current Durability \%})$$- Full Penetration: If the bullet penetrates, the target takes full raw flesh damage minus minor kinetic drag.
- Blunt Absorption: If the armor stops the bullet, the target takes reduced blunt trauma ($10\%\text{ to }20\%$ of base damage), while the armor loses durability points based on its material composition.
Armor Material Durability Multipliers
Not all armor classes degrade at the same rate. Armor material dictates how many durability points are stripped per impact in our Arena Breakout Armor Penetration Calculator:
| Armor Material | Durability Damage Multiplier | Repair Efficiency | Ballistic Profile |
| Aramid | 0.30x | High | Maximum structural longevity; degrades very slowly |
| Polyethylene (UHMWPE) | 0.35x | High | Lightweight tactical standard with great durability retention |
| Titanium Alloy | 0.40x | Moderate | Balanced protection against intermediate rifle calibers |
| Hardened Steel | 0.50x | Moderate | Heavy protection; loses integrity under rapid automatic fire |
| Ceramic Plate | 0.60x | Low | Shatters rapidly under repeated sustained hits |
Common Ammunition Matchups: Shots-to-Kill (STK)
Understanding caliber performance against popular armor tiers determines whether you should aim center-mass or prioritize limb-meta:
| Caliber & Ammo Type | Pen Level | Base Flesh Damage | Base Armor Damage | Shots-to-Kill vs. Tier 5 Chest |
| 5.56x45mm M995 | Tier 6 | 42 | 58 | 2 – 3 Hits (Immediate Over-Pen) |
| 5.56x45mm M855A1 | Tier 4 | 49 | 42 | 4 – 5 Hits (Shatters plate on shot 3) |
| 5.45x39mm BS | Tier 5 | 45 | 52 | 2 – 3 Hits (Consistent Penetration) |
| 7.62x39mm BP | Tier 4 | 58 | 44 | 3 – 4 Hits (High Blunt Trauma) |
| 7.62x51mm M61 | Tier 6 | 70 | 75 | 2 Hits (Instant Chest Kill) |
| 7.62x51mm M80 | Tier 4 | 81 | 48 | 2 – 3 Hits (Massive Flesh Pool Dmg) |
| 9x19mm PSO (Leg Meta) | Tier 1 | 77 | 12 | N/A (Aim for unarmored legs) |
How to Use the Arena Breakout Infinite Ammo Calculator
- Select Ammunition Type: Choose your caliber and bullet type from the dropdown to load baseline flesh and armor damage values.
- Choose Target Armor Tier & Material: Pick the opponent’s helmet or body armor class (Tier 1 through Tier 6) and material composition (Aramid to Ceramic).
- Select Hitbox Target Zone: Toggle between Thorax / Chest ($85\text{ HP}$) or Head ($35\text{ HP}$).
- Adjust Initial Durability: Move the slider to test encounters against already-damaged gear.
- Analyze the Shot-by-Shot Log: Review the step-by-step impact log to track the exact bullet that breaks the armor and lands the fatal kill shot.
Frequently Asked Questions
How many shots of M855A1 does it take to kill Tier 5 armor in ABI?
Using a standard M855A1 tier 5 armor ABI calculation, M855A1 ($4\text{ Pen}$) has roughly an $18\%$ chance to penetrate pristine Tier 5 armor on the first shot. It requires 4 to 5 chest shots to crack the plate’s durability and secure the kill.
What is the fastest killing caliber in Arena Breakout: Infinite?
High-tier battle rifle rounds like 7.62x51mm M61 and 7.62x54mmR SNB feature Tier 6 penetration, punching clean through Tier 5 and Tier 6 helmets for 1-shot headshot kills and 2-shot chest kills.
Why does armor material matter in ABI?
Armor material dictates repair penalties and durability loss per hit. A Ceramic vest absorbs the initial bullet effectively, but loses up to twice as much durability per shot compared to an Aramid or Polyethylene vest, making it far weaker against sustained automatic fire.
