Blizzard Entertainment has announced the opening of beta registrations for “World of Warcraft: The War Within,” inviting players to explore new subterranean worlds beneath Azeroth.
Danish from eXputer: "Despite Blizzard's attempt to give a fresh new spin to World of Warcraft, some fans still seem to be stuck in the past."
HG writes: "Blizzard is usually pretty bad at keeping secrets, but the company somehow managed to keep this one under wraps until now. Plunderstorm is a special limited-time event that’s basically World of Warcraft’s take on the Battle Royale genre."
