Heroes from Azeroth, Sanctuary, and the Koprulu sector have been sucked into the Nexus, a transdimensional storm. Stranded in a strange limbo of clashing universes, these combatants are joined by the same fate—to engage in pulse-pounding combat, to team up in a deadly struggle for survival, and to answer the age-old question...who would win? Heroes of the Storm draws in characters from all of Blizzard Entertainment's franchises, including World of Warcraft, Diablo, StarCraft, and Overwatch, as well as some of their older games.
