Hitzones

Sirens have two weak spots, which are the head and the neck. Although the damage multiplier of head zone is lesser than for the neck it still worth aiming for the headshot as Siren's head has roughly twice as less health than body. Sirens wear a metallic plating over their bodies, which reduces the damage when they are shot in the chest and hips, acting as a crude bullet-proof vest.

Head	x1.01
Neck	x1.1
Chest	x0.5
Hips	x0.5
All other	x1
