Shots-to-kill calculator
Pick a gun, a round and a target. Each hit deals gun damage × round multiplier × 2 ÷ (armor − AP + 2) when armor is above the combined AP of the gun and round, and full damage otherwise. A headshot is a critical hit: it multiplies damage by the gun's crit factor and meets the helmet instead of the body armor.

ADAR 2-15 with AP Bullet (AR) against Vida's Lv.5 Heavy Body Armor.
Assumptions
- Every shot hits the chosen location. For your own shots the game does not roll crits from the gun's crit rate: a shot is critical exactly when the aim cursor is on the enemy's head, and then it meets head armor.
- A shotgun's listed damage is split between its pellets, and every pellet hits. Armor reduces each pellet by the same fraction as a single bullet.
- Armor keeps its full value; the durability each hit strips (armor break) is not modelled. Enemy health is the base value from the enemy preset; difficulty health scaling is not included.
- Time counts the gun's full reload for each magazine emptied. Shotguns that load one shell at a time take longer. Launchers, the Fireworks Gun and the Explosive Arrow deal explosion damage and are not listed.
- Every gun is treated as physical damage. Bosses such as Pulu Pulu (×0.45) and Koko Koko (×0.33) take less of it; the factor is filled in when you pick a boss.
