Zombies (State of Decay)

The infected are individuals who succumb to a mysterious disease that transform them into a "zombie-like state. Like many "zombie plagues" in fiction, it is transferred by bites, however, unlike some zombie diseases, transformation into a zombie after a bite can sometimes be prevented with antibiotics, however, transformation into a zombie is irreversible. Also referred to simply as zombies or "zeds", the infected are the primary enemies in the video game State of Decay, where they have infested the entirety of the fictional Trumball Valley region of the US. The vast majority of the infected are "common infected", similar to zombies in other media, being slow moving unless alerted (at which point they are able to move very quickly). Most infected can only be killed either by head trauma, decapitation, or massive amounts of trauma such as explosions or being struck by a vehicle. Some individuals will undergo mutations, transforming into one of four "special infected.

SWAT Zombies are the most common special infected, not being truly mutated, but rather, simply being SWAT officers that were infected and transformed into zombies. They are slightly stronger than most zombies, likely simply do to their superior physical condition prior to infection, and are clad in body armor, making them resistant to gunfire.

Ferals are large zombies with a greenish tinge to their bodies, which prefer to walk on all fours. Ferals possess both superhuman speed and strength, with sharp bony "claws"- the remains of fingers that had flesh stripped way to reveal the bone. Ferals are extremely dangerous, especially to lone survivors. If one intends to engage a feral, they should avoid melee combat expect to finish as downed enemy and bring heavy, particularly fully automatic weapons. Explosives and vehicle impacts can also kill ferals easily.

Bloaters, also known as "Rotters", are slow, bloated bloated zombies, with a light greyish-brown tinge. Bloaters can be killed with a single attack anywhere to the body, however, when killed, they release a cloud of highly toxic orange gas. Striking bloaters with vehicles is to be avoided as they will contaminate the vehicle with toxic gas.

Juggernauts, also known as "Big Uns" or "Big Bastards" are massive zombies about two meters in height, so large, in fact, that striking one with a vehicle will severerly damage the vehicle. Juggernauts have superhuman strength, easily being able to pick up a man and tear them in half. While generally slow, they can move quickly in short-distance "charging attacks". Juggernauts can sustain large amounts of damage before dying, with explosives, Molotov Cocktails, and large automatic weapons such as the M249 SAW being most effective.
