The guide will be a list of all the weapons and their respective treshold. When I say treshold I mean that you meet point where you kill or stagger an enemy in a given amount of shot/time.
I will give the stats of most of the ennemis, potential spoiler are darkened.


- Basic ennemies stats -
enemy : HP / weakpoint multiplier
Shooter : 30HP / head 5x
Charger : 30HP / None
Striker : 20HP / head 3x
Giant : 120HP / head 1,5x
Big Shooter/Hybrid : 150HP / head 2x
Scout : 42HP / head 3x
Charger Scout : 60HP / None
Flyer : 16,2HP/ mouth 3x
Snatcher : 225HP / None
Big Flyer : 150HP / mouth 3x

Each damage value will be given in dmg (damage) per shot/pellet and prec.dmg
prec.dmg = precision damage
stg.dmg = stagger damage
body burst/shot = kill by shooting non-weakpoint area
head burst/shot = kill by shooting weakpoint area (mouth-shot for flyer)
pellet kill (shotguns only) = the number of pellet to kill an ennnemy (in the head when precised)
Falloff meter value : the amount of damage you would lose per meter above the effective range of the weapon which can be offset by the use of boosters

Most of the value given in this guide will be boderline unachievable but it give an idea of what difference you're making.

Damage boosters allow you do kill sleeper quicker and with less ammo. But i will focus on 2 main aspects for each weapons :

- particular treshold, a given damage bonus that allow weapons to 1,2 or 3 shot certain fows (ex. a damage bonus of 13% allow the Bataldo 3RB to one-shot strikers in the head)

- Falloff meter value, the amount of damage you lose per meter of falloff, which can be compensated with damage bonuses (ex. the Bataldo 3RB loses 2% damage for every meter of distance added higher than 10m)

It should be noted that it is quite difficult to calculate treshold with burst weapons as they tend to blow strikers head (10HP) off with the first or second bullet (same for shotguns)

As a closing note I would like to mention that i did not write "every" treshold as I would to keep a proper sleep schedule. However I'm planning on adding sentrys and melee too (Steroid and DEX) and maybe update/add some tresholds depending on feeback.
If there is a treshold that you saw was wrong or you would like to have one added, do not hesitate to post it in the comment section.

Sorry for my bad english as I am not an english native.
