Helmets

Description
Helmets are a random spawn on mid-game walkers. There are three types of helmets, the bone helmet, the military helmet, and the ballistic helmet. Helmets block low tier gunfire from weapons such as revolvers and pistols, and deflect melee weapons that are not aimed at holes in the helmet, or at the neck. The bone helmet has a hole by the walker's mouth, the military helmet has a hole for the entire walker's face, and a crack in the top of the helmet, and the ballistic helmet has a large hole in the back of the head. Helmets do not protect against decapitation, which makes decapitation a reliable way to take them on. Throwing knives also work quite well against the bone helmet, as it can be thrown close to the mouth and will go in instantly, instead of needing to aim the knife in a gap to brain the walker. The improved bow (and possibly the laminated bow) can pierce helmets from a close range, making it the easiest way to kill helmeted walkers.
