Horde

The Horde is a massive group of normal Infected who fast attack at once, reminiscent of the movie 28 Days Later, using their sheer number to attempt to overcome the Survivors. Hordes can occur due to a Survivor being splattered by a Boomer, setting off a car alarm, or just at seemingly random moments. The horde reacts violently to the pipe bomb and will ignore you to go for it. The Horde is prefaced by a musical horn cue in the soundtrack followed by a burst of techno music that plays until The Horde is significantly defeated. The infected have very little heath and a headshot with any weapon will kill one. Most second tier weapons can also down an infected with a well placed body shot. A Pistol requires 2-4 body shots to kill an infected, but are still a one shot kill in the head. Shoving an unaware infected in the back is also an instant, silent kill.

Appearances and Action
The Horde come in varying appearances, in both male and female. When not attacking, they are very vulnerable when sitting down, leaning on walls, or simply standing. They are easily provoked by light, sound, or touch, but are normally only dangerous in large groups or when completely surrounding a player. The heads, arms and legs can all be shot off, this happening easiest using a shotgun or hunting rifle. The infected react naturally to gunfire. Shooting one in the foot will cause a very different reaction than shooting one in the chest with a Pump shotgun, much like the Euphoria Engine. They are often seen doing very odd things (vomiting, attacking inanimate objects, fighting each other, etc.) but begin to rush at you when they spot you.
