Shadow of the Mad King
Release Overview
Halloween has a long history in Tyria, and in times past was always marked by the spirit of Mad King Thorn cavorting among the people unleashing his own brand of insanity. However, it’s been over 250 years since he was last seen, and for most people he is merely a figure of folklore. Despite this, rumors persist among the populace that something wicked this way comes.
Shadow of the Mad King is the first major game release for Guild Wars 2 and will go live on October 22. This new game update will include a number of new features for all of our players to enjoy, new content to explore and see, and a week-long Halloween event.
