Starting today till the end of the month, MapleStory Taiwan will be holding a special event where players will get to enjoy content from the popular manga and anime series, Attack on Titan. I am not sure if the Japan server already had this promotional event previously, but it seems really cool.
Players will be sent by an NPC through a dimension rift and find a way to close it, and of course lands upon a world ravaged by Titans. Before aiding familiar characters such as Eren and Mikasa in the battle, players must first embark on a training course on how to effectively damage Titans.
Other than meeting with several different Titans, there will apparently be a boss battle with the largest of them all, Colossus Titan. In conjunction with this crossover, there will be several Attack on Titan items on sale in the cash shop, as well as special costumes and exclusive loot drops.
