War is dark red with a mane and tail that turns from black to light grey. War possesses a blazing mane and apparent battle scars. The flames which engulf its mane, tail, and hooves ignite the undead on contact, transforming them into smoldering ash after ramming them two to three times. War also possesses infinite stamina.
Sometimes, if the player fast travels to Manzanita Post, a second War will be hitched to the post. This is a glitch. If it dies, nothing happens, and the regular War the player has tamed will be unaffected. This glitch also happens with the three other Horses of the Apocalypse.
Whistle for War, mount it and switch to the Blood Pact of another Horse of the Apocalypse then dismount, mount the other horse then switch back to War's blood pact and whistle. There will be two Wars near each other. (Note: do this in an open place so that the first War will remain in sight and can be caught up to.)
The above glitch works for all four Horses of the Apocalypse.
Rarely, War may randomly die. This is probably a bug.
War tends to follow the player if they jump off a cliff near him. (This will kill him)
There is a glitch in which if an undead pulls the player off of their horse, the undead may glitch first on top of War, before glitching down into War, and then walk along inside the horse, still chasing the player. War will move with the undead. The undead can still be killed normally and will hit the player normally.
There is a glitch when traveling to another destination. Sometimes War will be invisible, but his flames are still there. The player can mount him, but the horse will not move. After dismounting he should appear again.
When entering the invisibility glitch with War, his flames will disappear.
There is a glitch upon first entering Mexico, War's flames will go out for a while and then come back on when the Chupacabra is found.
Sometimes, the blue circle that signifies War's location will not appear, and you will be left to find War without the aid of the map.
