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.
 

• Halloween
  Halloween is coming! Festivities are afoot, and Tyria will be transformed with decorations, new mini-games, new dynamic events, and more. Despite the celebrations there are those who dread the coming of Halloween and all that it may bring, for it is the time of year when barriers between the realms are weakest. Be prepared for an epic adventure in four acts starting October 22 and running until October 31.
• Black Lion Trading Company
  Never one to miss out on an opportunity, Evon Gnashblade has stocked all new items at the Black Lion Trading Company, including Halloween costumes and new transforms that will allow you to play Costume Brawl with fellow costumed players.
• PvP Paid Tournaments
  Paid tournaments will be available for competitive, five-person teams. These tournaments require tickets to enter and give better prizes than normal tournaments. Participating teams will earn qualifier points that will allow them to compete in future, larger tournaments. Tournament tickets can be earned from winning normal tournaments or purchased in the Gem Store.
• Tyria Evolving
  The world continues to evolve with new events, jumping puzzles, bosses, mini-dungeons, and achievements appearing across a variety of maps.
