Horde

A Horde is a lot of zombies gathered together. This can be a combination of Normal zombies, tanks, blotters, crawlers, etc. A Horde is a survivors worst nightmare because some hordes can be dangerous enough to take out a whole community in whole night. Hordes of zombies tend to move as one due to a cause, maybe a sound, or a person or even a screamer and/or spitter. A screamer will turn a whole entire horde into red eyes, causing them the horde to be extremly deadly. A Spitter can be a direct reason of causing a horde, by a Spitter tracking its prey other zombies take notice and instinctively follow a Spitter.
