All NCSoft titles will be sporting events to celebrate Halloween. Guild Wars, Aion and City of Heroes will have special events, quests and rewards for players to participate in from now through each game's specified end date. Zombies, pumpkins, thrills and chills will greet players on log in so be sure to head into your favorite game to participate.

• Aion – Harvest Revel: The Harvest Revel is upon us once again! This year, the residents of Pandaemonium and Sanctum decided to treat their immortals with homemade treats and candy. However, in the ultimate Trick or Treat heist, a bunch of devious Shulacks have stolen the sugary, sweet lollipops and fled the two cities.
• City of Heroes: Not Even Pretoria is Safe from the Halloween Apocalypse! Even the utopian, clean streets of Emperor Cole’s empire hide dangerous secrets this Halloween season. Those caught “Trick or Treating” and knocking on doors in Praetoria, the Rogue Isles and Paragon City may be greeted with treats such as temporary costumes or tricks such as rocks or unique monsters. And no area is safe enough to repel zombie hordes, as the nefarious walking dead that will infest Praetoria, the Rogue Isle and Paragon City this Halloween, lead by powerful monstrosities such as Eochai and Jack in Irons.
• Guild Wars – Halloween Signals the Return of the Mad King: Once a year, Mad King Thorn and his spooky cohort return to Tyria for a creepy celebration full of new holiday quests, the Costume Brawl PvP event, Halloween-themed guild vs. guild battles, imposing new Halloween costumes, and lots of other surprises.
• Lineage: Lineage Halloween Event - Forget running from things that go bump in the night, you’re going to hunt them! Follow the story hints in the forums as they lead up to the monster-hunting Halloween Event. Players can use the Candle of Reminiscence to reallocate stats, hunt down monsters for their souls then trade them in for special Halloween-themed items. Watch out for tricks along the way as well, as players quest and conquer ghouls and monsters in their effort to obtain the Spartoi Doll.
• Lineage II – GM Event: Trick or Treat - This year the treats come swiftly during the Halloween Event. While out hunting for tricks and treats, players may randomly encounter an elpy. Tell this elpy the secret Halloween phrase and be transported to a special room of elpies. Once there, players will undergo a Halloween transformation and for a limited time will be able to collect as much loot as they can! The loot will vary, but players will have the chance to walk away with fun, useful and valuable items.
