In celebration of its 30th year, Blizzard announced today that it is relaunching three of its oldest games: Rock N Roll Racing, The Lost Vikings and Blackthorne. They are getting a little sophisticated at the Blizzard Arcade Collection, with varied features, including setbacks and extra levels, as well as a ‘museum’ of old development resources and interviews. It is now available for PC, although currently only if you buy Blizzard’s big pack of goodies from Blizzard.
