Dead Horse

 is the popular name for a mount which was included in the original Red Dead Redemption retail game, but was seemingly left out of the actual storyline. As a result, the mount is available for use (i.e. it appears within the game's code itself) but is not obtainable by ordinary means.

Description
While it has been suggested that it's an easter egg, the only known way to unlock the Dead Horse is by directly editing the Red Dead Redemption save game data itself. This implies that the horse, which clearly does exist within the original game code, is simply the remnant of some mission/item that was left out of the game's final release (but not completely removed from the code itself).

The horse appears to be missing its lower jaw and half of one leg, as well as being covered with claw marks. The horse appears very similar to the mutilated horse from the mission Spare the Love, Spoil the Child, leading some to suspect that the two mounts are rendered by the game engine using similar/identical art assets.

Obtaining
The only confirmed way to unlock the Dead Horse is to use an edited save file or mod one. As always, before attempting anything with the game save file, always back up some save data first; seemingly innocuous errors may result in file corruption if done improperly.

There are two rumors on how to get this horse.

Also, always remember to be careful when attempting to edit a save file, as Rockstar may ban you permanently for doing so.
 * 1) Rumors that it may be released in the Undead Nightmare DLC, possibly in October.
 * 2) Another is that if the owned horse dies 1000 times when called, it will be a zombie horse.

Trivia and Notes
Jack's Dead Horse.


 * What modders and other RDR enthusiasts have affectionately nicknamed the "Zombie Horse" is actually referred to the game (internally) as "@RIDEABLE_ANIMAL_HorseDead01"; however, lacking any kind of storyline (or a deed) to identify the creature, it's difficult to know what name (if any) the developers originally had in mind for it.
 * While the Dead Horse appears to be missing it's front left leg from the knee down, if the area where the missing leg would be is shot it still takes damage and spews blood as if the leg were there.
 * It may appear in the Undead Nightmare DLC Pack.

 * After you kill the bear in the mission Spare The Love, Spoil the Child go to the cave and you will find a the corpse of Jack's dead horse.
