Returning testers will notice many new features have been added since the closed beta runs, like events, a plethora of new cosmetic items, and more streamlined skill, talent, and crafting systems. And jetpacks -- who can forget the jetpacks! Players will also find over 80 dungeons, over 100 quests, new PvP maps, open Wilderness levels, customizable gear, and more... and that's only to start! The devs have an aggressive release schedule plan of adding new features and content on an almost bi-weekly basis throughout the beta.
