Pokémon Snakewood is a hacked ROM of Pokémon Ruby, created by ROM hacker Cutlerine. The game is set a few years after the events of Ruby, and you play as the younger brother or sister of Ruby's protagonist (called Landon in this game). The game takes place in a post-zombie apocalyptic Hoenn region, where the hero must fight his/her way through the decaying region to restore order.
Pokémon Snakewood begins with the player (Wraith (boy) or Jericho (girl)), waking up in a destroyed Littleroot Town with no memory of what has happened. Amidst the rubble of Professor Birch's laboratory, there are three Poke Balls containing Paras, Koffing, and Baltoy. After selecting a Pokémon, the player ventures out of the town to find Birch being attacked by a zombie, who then attacks the player. After defeating the zombie and its zombified Pokémon, Birch takes the player to Oldale Town, which has been turned into a fortified safe-zone. There the player is informed that the entire region has been taken over by a zombie apocalypse, and that player's older brother Landon (who is also the Champion) and his his girlfriend May have gone off to fight the zombies but haven't been seen since.
The player decides to investigate the matter by searching for them. On his way out of Oldale he is assaulted by a Deathcaller named Alicia, who claims to be testing his strength. After making his/her way to Petalburg, the player comes across a survivor. Before the player can ask about Landon, however, a horde of zombies appears and the survivor sacrifices himself to save the player.
After battling through a horde of demons in Petalburg Woods, the player makes it to Rustboro City, which is infested with zombies and more demons. There the player comes across Alicia again, who reveals that she was the one who left the demons behind to kill the player. The two battle again, and Alicia flees to Verdanturf after her defeat.
Then the player notices a conversation between a possessed body and another person, who claim they cannot be seen through the latter's forcefield. The player, intrigued by their air of familiarity and the fact that he can see them, goes to join them in battling the demons. The person introduces himself as a Taoist named Gleis, and the possessed corpse as his servant, Dantalion. At first shocked by the player's introduction, Gleis later agrees to have the player as an ally, after a battle to test his strength.
The player is told to meet Dantalion at Rusturf Tunnel. Now possessing a Triathlete, he informs the player that Gleis is waiting inside to fight back the demons. Inside the cave, Gleis tells the player that he intends to seal off the portal allowing the demons to pass into the human world, using May's friend Elise as a vessel for the portal. The player must battle back several demons trying to escape before the portal is sealed off. However, the energy given off by Gleis' spell destroys Elise's body. After thanking the player, Gleis goes on his way, leaving the player to go to Verdanturf Town.
After reaching Verdanturf, which is now a giant lava pit surrounded by rock wall, the player confronts Alicia and Pestilence of the Four Horsemen of the Apocalypse. The player battles and defeats Pestilence, and she flees. Alicia confesses that she was in fact the player's ally before he lost his memory when his house collapsed. She also apologizes for attacking the player and leaves. However, she drops a Pokedex on her way out, and the player recognizes it as May's. The player decides that he/she should head for Dewford, which is predicted to be zombie-free because it is surrounded by water.
After surfing to Dewford, the player makes a deal with the Gym Leader, Haruko, to investigate strange noises coming from inside Dewford Cave (now Solar Caverns) in exchange for a battle. The source of the noises turns out to be the Dragon King, Meteor. Claiming that the two have met before, Meteor battles the player and loses. He leaves, and the player heads back to the gym to battle Haruko. Second gym badge in hand, the player is contacted by Birch, and is told to go to Slateport to search for Landon and May.
Once in Slateport, the player comes across numerous zombified or "former" chefs. After some searching, the player notices something under a pool of water inside the shipping building. The object turns out to be the SS Cangrejo, a large submarine manned by a man named Usher. Usher asks the player to fix the ship's engine, and when he/she does, Usher thanks the player by dropping him/her off in front of the Cycle Road, on the other end of Slateport.
As the player makes his/her way up to Mauville, he/she is attacked by several strange Footmen. When the player reaches Mauville, Gleis appears and beckons the player to join him in watching the Footmen from before battle back several zombies and former chefs. Gleis explains that the Footmen are part of the Inquistion, a militant organization that is all that's left of Hoenn's collapsed government. Shortly after, the Inquisition's boss, a Taoist named Chloe, appears and vaporizes the zombies and former chefs, and orders the Footmen on to a new area.
Gleis tells the player to go to New Mauville, where Dantalion is waiting to give further orders. Once there, Dantalion briefs the player on the mission: To find out who has committed a murder in New Mauville, where all of Mauville's residents have taken up shelter from the zombies and Inquisition, led by Wattson. After some scouting, the player determines that the murder victim was killed by supercharged attacks by Electric-type Pokémon. With the only Electric-type user in the area being Wattson, the player immediately accusses him of the murder. Wattson gladly confesses that he was, and shortly defeats the player using his Electric-type Pokémon, which have been connected to New Mauville's generator to maximize their power (aka make them all Level 100).
The player, determined to defeat Wattson, finds a switch that shuts off the generator and promptly defeats Wattson, forcing him to flee New Mauville, only to be caught by the officer investigating the murder.
After this, the person must enter the Island of Calm on Route 110 and go through a frustratingly repetitive puzzle and fight the Deadly Seven (which is actually 10 people) and infiltrate the inside of the base to save Gleis and his Pokegear from the Inquisition. Upon defeating the leader of the base, Maifenense, the player returns the stolen Pokegear to Gleis, who gives him HM06 and an escape to Mauville City. At this point, the player goes north, and seeing Alicia, has another flashback. He defeats Alicia and Famine and they flee, allowing the player to head west.

Pokémon Snakewood also adds a new classification of being called Denjuu, which is a reference to the Telefang game series. As far as the hack's coding is concerned, Denjuu are Pokémon, but the story classifies them as a different group of beings from a different dimension called the Denjuu World. Unlike regular Pokémon, Denjuu have been shown to talk, and their names are stylized with all lowercase letters. Below is a list of known Denjuu:
