Halloween is less than two weeks away and NCsoft has its hands full with plans for holiday events in Aion, City of Heroes, Lineage, Lineage II, Guild Wars and Exteel. We've already told you about Aion's "Harvest Revel" event, which begins Oct. 25 and runs through Oct. 31. We've also reported on the festivities in Lineage and Lineage II, so let's jump right into the other MMOs.

The annual Halloween event in City of Heroes returns today as zombies, werewolves, Jack-o-Lanterns and other monsters descend upon Paragon City and the Rogue Isles. The attacks will end on Nov. 3, so you'll have plenty of time to participate.

Mad King Thorn returns in Guild Wars from Oct. 23 to Nov. 2 with a bag of tricks and treats. You can also participate in a new series of quests and a costume PvP brawl. Orange and purple paint will be free in Exteel from Oct. 28 to Nov. 4, and players will receive +50% bonus credits during the Halloween celebration. You can read all of NCsoft's holiday plans after the jump.

Aion – Harvest Revel
During the Fall harvest, the people of Atreia have always celebrated the bounty of the land. Years ago, the joy of the annual revels was troubled by an eclipse—a peculiar and magical eclipse that brought darkness to Asmodae and Elysea. Ever since, for days during Harvest Revel, the sky goes dark and the people of Atreia join in the hunt.

Asmodians celebrate the bounty through the Wild Hunt, racing after the Wild Kurthanir hunt leader and cooking special dishes made from the meat. On the other side of Atreia, the Elyos encounter undead creatures pulled back into a semblance of life by the power of the eclipse. Elyos must join roving Dark Night bands to hunt and destroy the undead before they invade Elyos villages.

Each day during Harvest Revel players will be rewarded for their investment with new lore and tasty treats including a Halloween Hat and candy that will transform players into in game creatures!

But non-tricksters fear not, there are plenty of ways to celebrate Halloween – participate in several special events (a new series of quests and a costume PvP brawl) or explore the decorated cities/towns adorned with Halloween décor.
