Mutants

Mutants are non-human creatures of the post-apocalyptic New Mexico. They are shown below.

Zombies
Zombies are feral, ghoulish creatures with a need of eating flesh. The zombies first started appearing in the 2040's, likely being a result of the nuclear fallout.

Contrary to popular belief, you do not turn into a zombie if you're bitten by one. Instead, the wound can be get gangrenous if untreated, and the amount of germs and bacteria they carry will most likely make you sick.

Bruisers
Bruisers are sentient, although looking like carnivorous beasts. They are descendants of the nuclear fallout, which simply mutated into hostile brutes.

Their muscle tissue is exposed and they have a little of thin, weak skin. That mutation made them abnormally strong, yet also much more prone to pain.

Bruisers' lifespan is significantly reduced, however they rarely die of age, as they're mostly killed by humans or other bruisers.

Lepers
Lepers are often mistaken as zombies due to their putrescent appearance. Some eat flesh as well, but unlike zombies they are not feral, albeit mostly isolated from the human society. Additionally, some of them try to blend into the human environment.

Their skin constantly decays as a result of mutations. They don't feel pain from shallow wounds.

Most of them form communities focused on searching for food, except for the "civilized" lepers.

Chupacabra
The Chupacabra is an intelligent feral predator, which once was a coyote but mutated into a two-headed beast. It is fast and agile, also possesses an ability of high leaps. Even if you're in a pack of highly experienced hunters, it is still extremely difficult to kill this monstrosity.

The Chupacabra is sensitive to loud sounds and can be easily distracted with them. It is also mostly nocturnal..

Wasteland Hounds
Wasteland Hounds are canines which have been bereft by their owners and have gone feral. They started grouping up in packs and hunting for lone prey.

They still can be tamed and domesticated.

Radiation Elementals
Radiation Elementals are the aftermath of the Altar's destruction. They are near invulnerable radioactive flesh creatures that can survive nearly all attacks if their nuclei, a gooey glowing orb, is intact.

They are not sentient at all and are feral, like Zombies.
