Question 1

What is TTK and STK in Arena Breakout: Infinite?

Accepted Answer

In Arena Breakout: Infinite, TTK (Time-To-Kill) is the duration in seconds required to eliminate an opponent, while STK (Shots-To-Kill) is the exact number of hits needed to overcome armor defense and reduce the target's HP to zero.

Question 2

Which ammo has the fastest TTK against Tier 6 body armor in ABI?

Accepted Answer

Tier 5 and Tier 6 armor-piercing ammunition such as 7.62x51mm M61, 5.45x39mm 7N22M/BS, 5.56x45mm M995, and 7.62x54mm 7N37 offer the fastest TTK against Tier 6 armor by reliably penetrating on the first shot.

Question 3

How does bullet penetration probability work against body armor in ABI?

Accepted Answer

For Tier 5 and Tier 6 body armors, a binary penetration threshold is used: if bullet penetration meets or exceeds armor defense, penetration chance is 100%; otherwise 0%. For lower tiers and helmets, penetration follows dynamic probability curves based on bullet penetration rating, armor durability percentage, and shooting distance.
