It’s the Halloween season again, and TERA’s Harvest Festival Hall event has returned for another year. For the rest of the month, players can get into the spooky holiday spirit by taking part in the Festival Hall dungeon event, where they’ll have to man the Halloween Cannons “to repel waves of monsters intent on stealing every last bit of candy they can get their grubby paws on.” To participate, players just have to talk to the witch Serena at the Eldritch Academy. Should they succeed in defending the precious Halloween confections, Serena will reward them with some Halloween candy of their own, which they can then trade in for a variety of seasonal goodies, including the exclusive Boneshaker mount and the looting ghost Pet Boo.En Masse is also rolling out special costume packages on the in-game shop, with new costumes available each week in October. This week, players can get their hands on the succubus-esque Devilicious costume (for the ladies) and the sentai-inspired Titan Force costumes (for the gents). Week two will feature police and nurse costumes, while week three will introduce cowgirl and wrestler costumes, and week four will wrap things up with undead costumes that are described in the press release as “glowing skeletons and mummy outfit[s].” For all the details on TERA’s Halloween festivities, check out the announcement post on the game’s official site.
