In the latest edition of the Elite: Dangerous newsletter, David Braben and crew refine the game's alpha and beta schedule. "The final stage of the Alpha [Alpha 4] will be released on May 15th and will be followed two weeks later by the first stage of the Premium Beta on May 30th," the letter states. Until then, Premium Beta purchasers are able to download the single-player combat build.
Frontier also talks up Alpha 4's 400 billion star systems, discusses its proprietary Cobra software tech, explores the Boötes constellation, and dishes on the game's three modes of travel: conventional drives, frame shift drives, and upgraded frame shift drives that permit full hyperspace jumps.
