Halloween is close by, and ArenaNet will be joining in on the fun. Guild Wars 2's first major content update is called Shadow of the Mad King. that will include a Halloween event, new minigames, new dynamic events, PvP paid tournaments, and more.
If MMO events is not your thing, the PvP paid tournaments is something to look forward to. It is still has the same 5v5 tournament format but has better prizes. You will require tournament tickets to participate, and you get to earn qualifier points that are needed to join bigger tournaments in the future.
Shadow of the Mad King is scheduled to go live on October 22.
