The idea of the Zombie is basic. Although there are many different sub-categories. These sub-categories are created by psychical aspects, length of reanimation, location of death, weather conditions, or even injuries caused by survivors unable to finish the poor zed off..The basic idea of how to dispatch a zed is to cause damage to the brain through psychical attacks, or a firearm. All zombies have varying muscular strength, although do no underestimate a zombie's strength. Due to no mental inhibitions, they do not tire, meaning the longer you fight them, the longer you are fatigued, they are not. They will kill you if you have a moment of weakness. Eliminate zeds as fast as possible.
Basic walkers are the most known and most famous types of z's. they can range in physical fitness, from skinny to overweight walkers. zombies have the basic attributes of the previous human before death and "Reanimation". At the beginning of the Z outbreak most z's will have little to no decomposition, just the occasional missing chunk of flesh from a bite. As the outbreak progresses survivors will encounter "Rotters" Or partially or completely decomposed zeds.
Not a large threat alone. But in a group they can be a massive threat to survivors. z's have a movement of a shambling limp, moving at a low speed. This may cause survivors to see them as easy to avoid, although this will cause them to rush headlong into a situation, allowing biters to move in behind them and box them into a corner or other z's. Condemning them to death if they do not analyse what they are doing
Runners/ Stalker Zeds
Runner Zs are one of the bigger threats to survivors. Fast moving as well as their blood thirsty nature. Chasing Survivors. These Zeds are a primary target and should never be overlooked when fighting hordes, as they will gain ground on Survivors and bring them down, either killing them or disabling them and leaving them for the slower "Walkers". Never try to out run the Runners. They do not tire like humans do. They only way to stop them from running is to disable their legs through severing large muscle groups or completely severing their legs. Other than that eliminate them as standard infected. There may be the chance that the "Runner" Category may also be pre-mortem humans, infected and driven insane with the need to eat flesh
Stalkers are a more feral type of zombie, human as standard, although they are not as "Human" As the other zeds. Stalkers are quadrupedal zombies. Nothing is known as to the cause of the animal like movement. As the author I theorize that the zombies brain has degraded so far that it stepped back on the evolutionary chain (No I am not completely sure that we are descendants of chimps) Reducing them to monkey like locomotion. This movement shakes and jerks their heads around, making them harder to hit with a ballistic weapon. This also increases their speed, making them faster than standard walkers, but slower than Runners. Due to their lowered profile they may be harder to spot in tall grass and dark environments. Due to their reduced intelligence, even below a walkers, they attack anything moving on sight, be it another zombie, or a rolling tire. The only creature not assaulted by them is their own specification of Z.
Crawlers/ Halfers/ Chopped/ Ankle biters
The crawlers are a well known, very, very annoying type of Z. As crawlers they are either completly disabled. As Described in the Runners section, they can be disabled through muscle severing or leg severing, Crawlers can also have their legs crushed by a heavy object or car. As crawlers they support their upper torso with their arms, crawling along on the ground slowly. As due to their low profile they are harder to spot, as well as their low speed makes them a highly dangerous zombie if not payed attention to. The second one neglects to pay attention they can be taken down by this. The zombie latching onto the survivors leg and biting down, infecting as well as disabling their leg.
The bonies are what you get when most of the flesh has rotted from the initial corpse leaving only heavily blackened, necrotic skin and limited tendons. They are the final stage of zombification and often do absolutely nothing unless a human or zombie gains their attention through interaction.
They have no eyes but would seem to have a form of echolocation as a deep humming can often be heard in their presence and they are not clumsy or shambling but slow and deliberate in their actions unless motivated to move more quickly.
Bonies are rarely seen as they most typically reside in large zombie nests like airports or shopping centers and don't tend to have much motivation to leave. They don't appear to attack out of blood lust but rather out of some will to make more zombies. They are arguably the elders or de facto alphas of any zombie pack or nest in which they reside; other Zed's follow their lead unless the hunger takes over and they become ravenous and savage.
