In celebration of their thirtieth year, Blizzard announced today that they are releasing three of their oldest games again: Rock N Roll Racing, The Lost Vikings and Blackthorne. It’s a bit of a hit in the Blizzard Arcade collection, with features that include backwash and extra levels, plus a ‘museum’ of old development assets and interviews. It is now available on PC, but currently only if you buy Blizzard’s large bundle of BlizzCon treats.
