Unleashed upon the world of Red Dead Redemption™, the Undead Nightmare Pack features an entirely new single-player campaign following John Marston as he tries to find a cure for the highly infectious undead plague spreading across the frontier.
In addition to this epic single-player adventure, the Undead Nightmare Pack also features a brand-new multiplayer mode in addition to new gameplay mechanics, weapons, undead animals and mythical creatures.
I installed it last night (big update). When you start the single player campaign, it gives you the option of the original game or the new one. It is more or less "
night of the living Red Dead" and has some interesting new features. The bad news: since it is a new game, none of your existing money or weapons carry over. There are no shop keepers, so your money isn't any good anyway! Right away it tells you ammo is very limited, and they aren't kidding, but you quickly get a new melee weapon: the torch
I've only played the first sequence in Blackwater so far, but it is pretty fun.
