Red Dead Redemption 2: Undead Nightmare 2

Undead Nightmare 2 is an expansion pack for Red Dead Redemption 2 made by Rockstar Games that adds a whole new story mode, focusing on Arthur Morgan as he searches for a way to stop the outbreak of supernatural creatures spreading around each of the states; not only zombies, but also vampires and werewolves.

The story of Undead Nightmare 2 is non-canon, because it coincides with the same timeline as Red Dead Redemption 2.

It is to be released October 28, 2019, three days prior to Halloween.

Plot
TBD

Undead (Zombies)
The undead are humans who were infected with the Mask's curse. They show no emotion, and only have the goal of feasting on human flesh, infecting more humans in the process. There are four types of Undead.
 * Normal - Slow, but can run for short periods of time. Can only be killed with a headshot or being lit on fire, but can be stunned with non-headshots.


 * Bolter - Fast zombies that are hard to hit. Can only be killed with a headshot or being lit on fire, but can be stunned with non-headshots.
 * Bruiser - Big, durable zombies that can charge and knock the player down. Can only be killed with a headshot or being lit on fire.
 * Retcher - Zombies that spit toxic snot at the player. Can only be killed with a headshot or being lit on fire. They explode upon death, which can kill the player.

Vampires
Vampires are either people infected with the Blood Curse or were born as so. They show pure hatred towards humanity, killing and draining the blood of their victims. They are strictly nocturnal, as sunlight burns them. There are three normal types, plus a fourth boss type.
 * Normal - Vampires with no special abilities, but are the only type that can carry firearms. Can only be killed with Silver Cross, Silver Ammo, Holy Water, Holy Light, Ornate Dagger, or just being hogtied in place until daylight comes. Garlic wreaths repel them, but do not kill them.
 * Swarm - Vampires that can transform into a swarm of bats to attack the player, but are generally easy to kill. Can only be killed with Silver Cross, Silver Ammo, Holy Water, Holy Light, Ornate Dagger, or just being hogtied in place until daylight comes, as they cannot transform into a bat swarm unless they jump. Garlic wreaths repel them, but do not kill them.
 * Shadow - Vampires that can transform into a shadowy mist which can be hard to spot by the player during the night, and can ambush the player by doing so. Can only be killed with Silver Cross, Silver Ammo, Holy Water, Holy Light, and Ornate Dagger. Can be hogtied, but can transform into shadowy mist and escape. Garlic wreaths repel them, but do not kill them.
 * Overlord - Beastly, large, powerful vampires that no longer look completely human, but a combination of man, bat, and dragon. They have the ability to fly, and can instantly kill the player by pinning them and draining their blood if the player doesn't break free. Can only be killed with Silver Cross, Silver Ammo, Holy Water, Holy Light, and Ornate Dagger. Cannot be hogtied. Garlic wreaths repel them, but do not kill them.

Werewolves
Werewolves are people who can transform into a bipedal, wolf-like beast under the Moon Curse, and have a savage hunger and a vigorous instinct to hunt. They have immense strength and are very fast. They are nocturnal, but can only be found during a full moon. They can be skinned for their pelt, meat, etc., just like regular animals. There are four variants plus a legendary boss variant that can be found in Tall Trees.
 * Timber - A werewolf with black colorations much resembling a timber wolf. Can only be killed with Silver Ammo and Ornate Dagger.
 * Grey - A werewolf with grey and white colorations much resembling a grey wolf. Can only be killed with Silver Ammo and Ornate Dagger.
 * Rougarou - A light brown variation of werewolf that can only be found in Bluewater Marsh and Bayou Nwa. Can only be killed with Silver Ammo and Ornate Dagger.
 * Snowy - A white variation of werewolf that can only be found in Grizzlies West. Can only be killed with Silver Ammo and Ornate Dagger.

The Goatman is unique to the Obediah Hinton survivor mission "An Unforgivable Sin - IV" (see Missions) at Butcher's Creek, where Arthur must search for a special black goat as a sacrifice to the pentagram at the abandoned shack outside of Butcher's Creek's boundaries. Upon being killed, its horns can be cut off as a trophy.

The Four Horses of the Apocalypse (Mythical Animals)
The Four Horses of the Apocalypse are unique horses with unlimited stamina, invincibility, and their own unique special abilities. They are found in separate areas on the map. The Four Horses of the Apocalypse consist of: War, Pestilence, Famine, and Death.
 * War - A crimson-colored horse with flames trailing from his mane and tail. His special ability is igniting every enemy he comes in contact with. He can be found in the open desert near Armadillo, New Austin.
 * Pestilence - A red-eyed albino horse with blood dripping from his eyes, patches of scars on his body, and a green miasma emitting from his body. His special ability is stunning enemies on contact. He can be found in Tall Trees.
 * Famine - A dark brown horse with locusts swarming his body. He is the fastest of the Four Horses, and his special ability is to send swarms of locusts at enemies. He can be found near Butcher's Creek in Roanoke Ridge, New Hanover.
 * Death - A multi-colored black, brown, and grey horse with ghastly white eyes and a white mist trailing from his body. His special ability is to explode the heads of the Supernatural upon coming in contact with them. He can be found anywhere on the map, but has the highest chance of spawning in Bluewater Marsh, Lemoyne. Alternatively, he is rewarded after completion of the Undead Nightmare 2 story mode.

Unicorn (Mythical Animal)
The Unicorn is a very rare mythical animal that can be found anywhere on the map. It is pure white, and has a trail of rainbows shooting from its back. It has infinite stamina, and cannot die from fall damage, as it slowly hovers down to the ground while it is in the air.

Manmade Mutant (Mythical Animal)
The Manmade Mutant is a mythical animal unique to the survivor missions "The Mad Scientist - I", "The Mad Scientist - II", and "The Mad Scientist - III". In the third mission, the creature comes to life as an abomination and starts to go on a violent rampage throughout Annesburg.

Mechanics
There are many mechanics present in Undead Nightmare 2 not present within the base game that relate to the mechanics of the original Undead Nightmare.

Town Defense
Sometimes, the towns and cities around the map will be under attack by the undead or the supernatural. The player must clear the location of any present undead or supernatural. Once the zone is cleared, rewards such as ammo are given, and the player will be allowed to sleep safely in a bed. Over time, the town/city will become filled with undead and supernatural, and the player must return to aid the survivors once more.

A unique town defense scenario occurs during the survivor mission "The Mad Scientist - III", where the player must kill the Manmade Mutant mythical animal boss at Annesburg.

Graveyard Cleansing
Mostly mission-specific, the player travels to graveyards around the map to cleanse them of the undead. The cleansing process starts once the player burns a single coffin with the torch, then must burn the rest of the coffins. Once all the coffins are burned, the player must destroy all of the undead. Upon burning the final coffin, a unique undead bursts from its slumber. Cleansed graveyards cannot become overrun with undead again.

Catacomb Cleansing
Mostly mission-specific, the player travels to ancient catacombs around the map to cleanse them of vampiric sources. The cleansing process starts once the player enters the catacombs and raises the silver cross. Then, the player will awaken sleeping vampires that must all be destroyed. After a unique vampire is destroyed, the player must place a garlic wreath at the entrance of the catacombs to cleanse them.

Den Cleansing
Mostly mission-specific, the player travels to werewolf dens hidden around the map to cleanse them of the lycanthropes that reside within. The cleansing process starts automatically once one of the werewolves within the den detects the player. After killing each werewolf including the unique pack alpha, the den is cleansed.

Trivia

 * The legendary Werewolf in Tall Trees is a reference to the rumor of a werewolf in Tall Trees in Red Dead Redemption. However, the werewolf in Red Dead Redemption was proven fake.
 * Dr. Frank Styne is a wordplay on the famous character Dr. Frankenstein.
 * The Manmade Mutant is a reference to the "Manbearpig" from South Park. The Manmade Mutant appears in the base game as an easter egg, but never comes to life.
