All 74 Ammo Types by Caliber in Arena Breakout: Infinite

In Arena Breakout: Infinite, ammo types are the different rounds your guns fire. They're split across many calibers, and they differ mostly in two ways: how well they get through armor and how much harm they do to a target without armor. Picking the right round for the armor you're facing can be the difference between a quick kill and a fight that drags on.

How Penetration and Armor Levels Work

Every round has a penetration number, and that number decides how well it gets through armor. Armor comes in six levels, from 1 for the lightest protection up to 6 for the heaviest. Each 10 points of penetration works out to one level, and players call this the round's pierce level.

When a round's level is higher than the armor it hits, it almost always gets through and does close to its full damage. When the levels match, it usually gets through but does less. When the round is weaker than the armor, its chance of getting through drops, and so does its damage.

Armor also wears down with every hit, and a worn plate lets through rounds that a fresh one would stop. Each round has an armor damage value that sets how fast it chips away at a plate. Even a round that gets through may need several hits to break a fresh plate, and each hit on a damaged plate works better than the one before.

Why Calibers Decide Which Ammo You Can Use

Rounds are grouped by caliber, which is their size. Each gun is built for one caliber, so you can only load the rounds that match it. The 5.45x39mm rounds fit the AK-74 family, 7.62x39mm fits rifles such as the SKS, and 9x19mm covers pistols and submachine guns. The 12x70mm rounds are for shotguns, and several other calibers make up the rest.

This is why ammo choice starts with your gun. A pistol round won't fit a rifle, and a shotgun shell won't fit anything else. Once you know your gun's caliber, the rest of the choice comes down to armor and budget.

Armor Penetration vs. Flesh Damage

Most rounds trade one strength for the other. A round that gets through armor usually does less damage to bare flesh, while a round with strong flesh damage often can't get through a vest. There are exceptions, so check each round's numbers before you stock up.

Armor only protects the parts of the body it covers, and a vest doesn't cover your arms or legs. Shots to those areas skip the armor math, so even a weak round can do real harm there. That makes limbs the usual fallback when a plate is too strong for your round.

Flesh-damage rounds such as the DumDum trade penetration for raw damage, which makes them a good fit for lightly armored targets. If a plate is too strong for your round, you can also keep hitting the same spot, since each hit wears it down.

Ammo Limits by Raid Mode

The game caps how strong your ammo can be based on the mode. Normal and Lockdown raids each set a maximum tier, while Forbidden Zone lets you bring the strongest rounds. The tiers line up with pierce levels, and the game won't let you equip ammo above your mode's cap, so the top rounds stay out of easier raids even if you own them.

Best Ammo for Each Zone in Arena Breakout Infinite

In Normal raids, the usual pick is the 5.56x45mm M855A1 or the 7.62x39mm BP. Both sit at level 4, which makes them the budget default, and they're cheap enough to stock up on. The 5.45x39mm BP is a similar cheap choice for AK-74 style guns.

Lockdown allows level 5 rounds, which is the level you'll want against level 5 plates. The 5.56x45mm M995 and the 7.62x54mm 7BT1 both reach that level, so they're worth a look when you need to punch through.

Forbidden Zone has the strongest rounds. The 7.62x54mm 7N37 sits at the top for penetration, with the 7.62x51mm M61 and .338 AP close behind. These cost the most, so save them for the zone where they matter, since wasted shots add up fast.

Shotguns split into two jobs. Among 12x70mm rounds, the Armor-Piercing Slug works best against armor, while most buckshot is meant for unarmored targets. In 9x19mm, most rounds are weak against armor, and the 7N31 is the notable exception.

Where to Get Ammo

Most ammo comes from raids. You'll loot rounds off the map, and ammo boxes and weapon cases often hold them as well.

You can also buy ammo with Koen, the in-game money. Koen comes from loot, selling items and trading, so what you bring out of raids also funds your ammo. Some ammo can be crafted too, and the top-tier rounds are made at the Workbench.

FAQ

What calibers are in Arena Breakout: Infinite?

Besides 5.45x39mm, 5.56x45mm, 7.62x39mm, 7.62x51mm, 9x19mm and 12x70mm, the game has .338, .44, .45, 5.7x28mm, 5.8x42mm, 7.62x25mm, 7.62x54mm and 9x39mm.

Which rounds get through level 6 armor?

The rounds that reliably get through the top armor level are the 7.62x54mm 7N37, the 7.62x51mm M61, the .338 AP and the 7.62x54mm SNB. Every other round can only get through level 6 once the plate has worn down.

Can weaker rounds still get lucky against level 5 and 6 armor?

No. There's no random chance for a weaker round to punch through level 5 or level 6 armor. Those rounds can still get through, but only after the plate has been worn down.

Are shotgun slugs better than buckshot against armor?

Yes. The Armor-Piercing Slug lines up with level 3 armor, while Type 5, Type 7 and Type 8 buckshot sit far lower, so they hit hard against bare skin but are best kept for unarmored targets.
