Halloween Episode / Video Games

• Every October, Artix Entertainment games like AdventureQuest and DragonFable have "Mogloween" quests, each year producing a new mini-story arc. They also have Frostvale in December and Hero Hearts Day in February.
• Batman: Arkham Knight takes place on Halloween and features the Scarecrow as the main villain. What makes this a significant Halloween Episode requires a bit of explanation. Scarecrow, aka Dr. Jonathan Crane, is a long-standing villain in Batman's Rogues Gallery who uses an inhalable fear toxin to make his victims experience their worst nightmares. One of the effects of the Evil Power Vacuum left by Joker's death at the end of Batman: Arkham City is that many of the Rogues step up to try their hand at taking over and holding Gotham in their grip. Scarecrow is much more ambitious, wishing to spread a much more potent form of his fear toxin not only across Gotham, but across the entire Eastern Seaboard, locking a significant portion of the US population into endless nightmares forever. This effect is explored in fairly horrific detail throughout the game, and Batman himself finds himself haunted by the ghost of the Joker who lives within his mind, due to Batman's exposure to Joker's tainted blood in the previous game. The mooks roaming around note that the fact that Scarecrow chose Halloween to enact his plot proves he has a sense of humor.
• Magia Record: Puella Magi Madoka Magica Side Story: For Halloween in 2017 the game introduced the Halloween-themed Karin. It also ran a special event, "Magical Halloween Theater", where characters put on a play for some young children; Kyoko and Felicia got special Halloween costumes.

• Team Fortress 2 has run special Halloween events every year since 2009, featuring bosses and enemies ranging from ghosts, giant undead headless monster wearing a pumpkin on its head that runs around beheading people, giant floating eyeballs that shoot exploding eyeballs, angry magicians, skeletons, and a haunted carnival. The mercs also get to find and wear unique, Halloween-only cosmetics during these events.
• Halloween is one of the major event holidays in Animal Crossing both in the Nintendo GameCube version and in the City Folk version, where you buy candy throughout the month of October in Tom Nook's store and give them to villagers to prevent them from playing tricks on you by transforming your clothes and pocketed items into Halloween themed items, while trying to find the real Jack (one of the special holiday NPCs) who all your villagers are dressed as and give him candy in order to get the Spooky furniture series from him. Though this is the point of the holiday in both versions of the game, there are some subtle different features added to the holiday in the City Folk version, such as being able to get villagers who are inside their homes to give you candy with a complete costume outfit which was not possible in the GameCube Animal Crossing's version of the holiday.

DLC, which opens up a new area of the Floating Graveyard and a side plot in which Cicini and Syaro, who are from the outside world, introduce Halloween to the island, with Lilith designing costumes.
