Blizzard Entertainment deployed the Battle for Azeroth Alpha Build 26433 which introduced the Battle for Lordaeron scenario. If you loved the cinematic, this scenario takes place minutes before the cinematic, and beyond -- ending with the capture of High Overlord Saurfang.
From the point of view of the Horde, first they battle in the Ruins of Lordaeron; and shortly after, a team is put together by Nathanos Blightcaller to rescue Saurfang from Stormwind City's The Stockade.
Both scenarios lead to the journey into Kul Tiras or Zandalar, and the responsibility to heal the wounded world with the Heart of Azeroth, gifted by Magni Bronzebeard.
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."
