Due to player feedback, Artix Entertainment has announced that the start of the Adventure Quest 3D closed beta will be delayed slightly to July 26th. During the closed beta, players will be able to take part in 11 new dungeons with several new features as well. Artix is hoping that this will be "the shortest closed beta ever" and anticipates that open beta will begin from 1 to 7 days later.
The best news for players is that there will be no character wipe, though levels and gold will be reset during the closed beta.
Artix also hopes that the Android beta will begin soon after the Steam open beta.
You can read more about the new content for closed beta and see the schedule of events on the Adventure Quest 3D site.
