How Ammo Works
Every caliber carries the same three types, so the choice is always the same three-way decision regardless of what you're shooting.
FMJ
DefaultShown in-game as Standard. Available from the start on every weapon that uses the caliber — no unlock, no cost.
HP
Early UnlockShown as Flesh. Unlocks span WARDOG Lvl 6 to 95, and every confirmed price is a flat $5,000.
AP
Late UnlockShown as Piercing. Unlocks run Lvl 63 to 140 — far beyond HP. Prices aren't confirmed yet.
The Most Important Section On This Page
HP Is Early Game, AP Is Late Game
Read the two unlock columns side by side and the split is stark. Every HP unlock sits below Lvl 95; the lowest AP unlock is Lvl 63 and they climb to 140. For most of your playtime, HP is the only ammo upgrade actually available to you.
Earliest HP Unlocks
5.56x45mm is the caliber of all three free starting rifles, so its Lvl 10 HP unlock is the first upgrade most players can actually use.
Latest AP Unlocks
Notably, AP order doesn't track HP order — 7.62x39mm has the earliest AP (63) despite a mid-range HP unlock.
The Verdict — Run Standard by default — it's the best go-to middle-ground ammo. Only switch to HP when you're specifically aiming for legs and arms. 12 Gauge is the sole exception to everything here: it has a fourth type, Rifled Slug, and none of its unlock data is confirmed.
Ammo Types
Every caliber uses the same 3 core ammo type names, regardless of which weapon or caliber they're loaded into. 12 Gauge additionally has a 4th type, Rifled Slug, not shared by any other caliber.
| Type | In-Game Name |
|---|---|
| FMJ | Standard |
| HP | Flesh |
| AP | Piercing |
Note
Damage Uses A Full Hit-Location Model
Damage isn't just chest-vs-headshot — there's a full hit-location model: head, chest, stomach, arms, and legs are all separate zones. Per-zone damage multipliers aren't confirmed yet.
