If you're talking about the outfit then you have to complete all the undead challenges(not including the tomahawk challenges and the explosive rifle challenges).
only if you aquire the blood pacts
I dont think so
No. War and the other three Apocalypse horses were made only for Undead Nightmare.
its on Undead Nightmare
You cannot get Red Dead Redemption - Undead Nightmare on the PlayStation Portable.
No you can only use them in the undead nightmare.
The fourth horse of the apocalypse, Death has the ability to instantly kill any enemy in the game by simply running into them.
The four horseman are Death, War, Pestilance, and Famine.
No you cannot join with the zombies in undead nightmare
no you have to have undead nightmare..... if u do want the horses you either have to download undead nightmare or buy it at the store.. but i recommend downloading it...
Undead nightmare is a addaption to rdr. Like a extentionpack but diffrent
