Elite: Dangerous' premium beta is coming next Tuesday. In newsletter #28, Frontier Developments said that Premium Beta 2 will begin on June 24th and include several new features, including gameplay optimizations, three new star systems, high-resolution screen capture, German localization, and the Zorgon Peterson Hauler trading ship.
Premium Beta 2 will begin with a wipe, although Frontier will be giving players in-game credits that correspond to progress made to date. Players can buy into the premium beta only through July 15th, which could indicate that the standard beta test is slated for later this summer.
