This expansion added a new campaign for each faction (a prologue campaign for the Orcs and an epilogue campaign for the Humans), new multiplayer maps, and a new setting (the hellish world of Draenor), while expanding the use of powerful Hero units. The game received an expansion pack by Cyberlore, titled Warcraft II: Beyond the Dark Portal, on April 30, 1996. Set six years after the events of Warcraft: Orcs & Humans, where the Orcish invaders have conquered the kingdom of Azeroth and driven the Human survivors out through the Great Sea, the game pits the Orcs (now allied with trolls, ogres, and goblins) against the Human kingdom of Lordaeron (now allied with the high elves of Quel'thalas and the dwarves and gnomes of Khaz Modan). Warcraft II: Tides of Darkness is a medieval-fantasy real-time strategy game developed and published by Blizzard for the PC (running MS-DOS) and Macintosh on December 9, 1995.
