The Sights And Shocks Of Red Dead Redemption's Late October Undead Nightmare

Zombie bears. Desperate people who need rescuing. The great weapon of Holy Water. A flaming horse called War. A plague of violent weirdness is coming to Rockstar's hit western Red Dead Redemption. The forthcoming Undead Nightmare is infested with it.

The zombie-filled fall expansion to Red Dead Redemption, which will be available for download on the PlayStation 3 and Xbox 360 on October 26, is a grander project than any of the previous additions to Rockstar's game. It is the biggest bundle of downloadable content since the company's Grand Theft Auto IV episodic expansions last year. While Undead Nightmare is not as huge — or as expensive — as those GTA extras, I recently saw firsthand at Rockstar's New York office how impressively deep and transformative this new helping of horror is.

Undead Nightmare is a standalone menu option, a separate sliver of Red Dead Redemption that public relations representatives for the game told me occurs during the "homestead" portion of the base game. They won't say if it "counts," if it is "real." Then again, players of the original Red Dead Redemption will recall that game had at least one hint about the supernatural in its otherwise-realistic setting.

(Check out the official Undead Nightmare trailer.)

John Marston is the hero in Undead Nightmare. In a cut-scene I was shown, he encounters Redemption's creepy gravedigger Seth who is playing cards with an even creepier and nearly motionless zombie named Moses. Marston, still voice-acted by the same guy who did him in Redemption, as are the other returning characters, is incredulous: "I've seen husbands eating wives, mothers eating sons!" He wants to know what's up.

After some chatter, Marston got on his horse. It was a zombie horse. I was warned that the rotting steeds are loyal but harder to control. This one was, sometimes steering with a half-mind of its own but exercising more endurance. Zombie horses can be found in the wilds of Undead Nightmare and broken in, but I was more delighted to learn of an alternate way to obtain one. If your normal horse dies in the expansion and you make Marston whistle, the zombie version of his dead horse trots over.

The conversation with Seth had opened one of Undead Nightmare's new elements, five zombie-polluted graveyards. I described one of them last week. Each is cleansed with a combination of torching coffins, shooting zombies and fighting a zombie leader of some sort.

Undead Nightmare looks different from Red Dead Redemption. The color palette is tinged with sickened greens and the skies above its familiar terrain are darkened. Zombies and zombie animals are everywhere. As I rode Marston west on his zombie horse I was distracted by what I thought was one of the new "random events," the zombie versions of the robberies, hunts, and suicides that populated Redemption's west. I never got a chance to find out because I was set upon by zombie animals. Wolves, I think they were. Like zombie people, they were harder to kill then their properly-born counterparts.

The military has established safe zones in Undead Nightmare. In these few places, you need not worry about zombies. Elsewhere, they shamble and march. Towns are taken over. I rode into one where the hordes of undead had forced its surviving citizens to the roof. When reaching such towns, a town safety meter appears atop your TV, shifting toward the positive as you kill zombies or head to the roofs and help arm the survivors. Cleared towns become save points, though they can be overrun again. You won't be able to save in the wilderness in Undead Nightmare. There be zombies.

Human zombies groan through Undead Nightmare in four types: standard Undead, nimble Bolters, bulky Bruisers and projectile-vomiting Retchers.

In Red Dead Redemption there were outlaws to hunt. In Undead Nightmare, there are missing people to rescue. Rockstar let me send Marston toward an icon on the mini-map which represented a big house overrun by the recently un-deceased. The missing person was in the house, anxious for me to clear the zombies and let him on my horse. In this fight, I tested some of Marston's new weapons. Zombies don't shoot guns, but they attack in packs. Against them, the new blunderbuss is a one-shot kill. Holy water is essentially a tossed grenade of zombie-frying potency. Zombie bait is another throwable item with a stink that attracts zombie. Toss bait. Let them gather. Bless them with holy water. Zombie problem solved. Rescued people must be brought back to safe zones.

Undead Nightmare has quests and more "stranger" missions, the latter of which were the intriguing adventures spurred by odd people who popped up in various parts of the Redemption world. Undead has new outfits and hunting challenges as well as the promise of mythical creatures, such as the Four Horses of The Apocalypse: War, Death, Famine and Pestilence, each with special abilities. The score is new, composed by the musicians behind the music of the original game.

Mysteriously, the game also features a "new location," the Rockstar reps told me, though they were cagey about where on the map it would appear.

I wasn't able to try the game's new multiplayer mode, which was described to me as a variation of a "horde" mode. Two to four players team up to fight waves of increasingly tougher zombie hordes, racing toward lighting strikes that deposit ammo and rushing against the clock to rack up a high score.

Rockstar's Undead Nightmare will run about five hours in single-player and cost $10. It is the first expansion to Red Dead Redemption to primarily offer content for solo players. It will require players to own a copy of Red Dead Redemption, and it will be out just before Halloween.

Other game creators have done the zombie thing before. Undead Nightmare is Rockstar's first stab at it. What I saw was eerie and violent and not as tonally jarring as I suspected. As I controlled John Marston in Red Dead Redemption, through his eyes I saw many peculiar characters, many strange things. On a zombie horse, I would be ready to see more, whether it is real or whether it is just a nightmare.
