World of Warcraft has officially begun its alpha for The War Within. Over the next couple of months, lucky players will be incrementally invited to test various zones from The War Within as the game is further developed, leading to the beta test period planned for late spring or early summer. Each build will add new sections to the game until much of the expansion is available, including most of the zones, dungeons, Hero Talents, and other features in the game. Alpha marks a major milestone in the development of the World of Warcraft expansion, and the hype is already growing to a fever pitch across the community.
