The Aion Classic version announced in May, as it turned out, will be available soon. The developers have set the date for June 23rd. However, for now, you will have to play on servers located in North America.
Aion Classic will be distributed free of charge with the option to purchase a Siel’s Aura subscription for faster development. In total, options are available with 30, 90 and 365 days. They also promise a battle pass with additional quests, rewards and premium currency.
The western version starts with version 1.0, and then updates 1.5 and 1.7 will gradually come out. The rate at which patches arrive will depend on how quickly players progress through the content.
Additional information can be obtained on the official website of the project.
