Within the next four weeks, NCsoft will treat European and North American gamers to two opportunities to jump into the world of Aion and explore Atreia as Asmodian or Elyos characters ahead of its release in Europe on 25nd September and North America 22th September. Aion’s Open Beta Test featuring version 1.5 will take place 6-13th September and will include numerous Western enhancements, including improvements to Aion’s innovative character customisation with a host of Western styles, as well as new zones, instances, skills, quests and continued game balancing and improvements. Open Beta will retain a level cap for both Elyos and Asmodians characters at 30 allowing players to focus on getting to the same level so they can explore the lands of Atreia together, as well as the Abyss.

Players who have pre-ordered Aion will be treated to a Pre-Select and a two-day Headstart period giving them the opportunity to explore, organise and progress through the game prior to the official launch. Pre-Select will take place on 18th September, while Aion’s Headstart will begin 20th September. Players can still participate in the Aion’s Pre-Select and Headstart programs by pre-ordering the game through several participating online and brick-and-mortar retailers.
