Four Horses of the Apocalypse

The  are some of the mythical creatures unleashed in the Red Dead Redemption Undead Nightmare DLC pack.

Characteristics
These new mounts must be found and broken by John Marston and will aid him in ridding the frontier of the zombie plague.

They are War, Famine, Pestilence, and Death.

Each of them possesses a special ability:
 * Pestilence has infinite stamina and a very high pain threshold. A small cloud of greenish mist circles around it.
 * Famine has infinite stamina and has a swarm of locusts around it, though this is useless since Pestilence, War, and Death also have infinite stamina.
 * War has amazingly high stamina (not infinite, however nearly impossible to diminish) and anything its fiery mane and hooves touch will burst into flames.
 * Death has infinite stamina and it has a wind of death around it which causes the zombies' heads to explode on contact.

If a Horse of the Apocalypse dies, it cannot be called back until you complete the game or find Death, and get the challenge to get their deeds or "blood pacts". Death's is given to you when you break it.

Locations
When exploring the map, a blue marker on the radar will signify if you are close to these or any other mythical creatures.


 * Pestilence is located around the West Elizabeth region in Tall Trees, between Manzanita Post and Aurora Basin, and in the Great Plains southeast of Beecher's Hope.
 * War is located around the New Austin region between Benedict Point, Tumbleweed and Gaptooth Breach and it is also located near Thieves' Landing, Mescalero, and right outside MacFarlane's Ranch. War can also be located near Coot's Chapel.
 * Famine is located in Nuevo Paraiso region, between Chuparosa, and Tesoro Azul and can also be found northwest of Torquemada.
 * Death can be found between Las Hermanas, Sepulcro and Agave Viejo. Death may also be found in Gaptooth Breach and at the Scratching Post. Can also be found at the regions you found the other horses at. Death can also be given to you after completing the game storyline.
 * Don't get disappointed if you don't find the horses in the precise locations listed here because the overall locations are Pestilence in Tall Trees, War in New Austin, Famine in Mexico and you get Death as soon as you finish the story.
