Instead, they have rediscovered their noble, shamanistic heritage. Although not quite heroes, the orcs are not the villains they were in the previous games. In Warcraft III, the orc side is still called The Horde and is composed of the orc, troll, and minotaur peoples. Wiii.net Note - Later in the storyline the Horde is to ally with the Alliance to fight the Burning Legion. Their return to nobility and a shamanistic heritage is seen throughout the Horde.
Grunts are no longer savage and bloodthirsty warriors.
Little is known of this race thus far. As for the undead, they are called The Scourge, and they are also a villainous blight on the world, consisting of all manner of the living dead. They have not been seen in any screenshots, and only two Demon Units, the Infernal and Demon Warlock, have been released. The reason for this is Blizzard is really still developing the race and will release more information at a later point. Because the game takes place 15 years after the events of Warcraft II and follows up on the untold story of Blizzard's cancelled project Warcraft Adventures, several familiar faces will return in the game.
