Warcraft II: Tides of Darkness (usually simply called Warcraft II; sometimes abbreviated to WCII, WC2, or War2) is the second, highly popular real time strategy game from Blizzard Entertainment set in the Warcraft universe. The novel Tides of Darkness, by Aaron Rosenberg, focuses on the events in this game. Both Tides of Darkness and Beyond the Dark Portal were later compiled and ported to the PlayStation and Sega Saturn as Warcraft II: The Dark Saga.
