not having done enough to defend their home, and of two Human kingdoms, which advocated exterminating the remaining Orcs rather than keeping them in captivity. One Orc clan that had fought in the Second War's final battle was unaccounted for. Although the Dark Portal had been destroyed, a tear in reality hovered over the ruin. New features The expansion adds two new campaigns and several multiplayer maps. The expansion also adds a new swamp tileset for the world of Draenor. The new campaigns feature ten new heroes for Warcraft, five for the Alliance and five for the Horde. Warcraft II: Tides of Darkness had a few hero units, but these units were only marginally stronger than their basic unit and they had their own unique sayings different from their non-hero counterparts. The new heroes have increased unit statistics, making them more powerful than regular units, have their own unit portraits, and their own speech. The Alliance heroes are Alleria (Ranger), Danath (Footman), Turalyon (Paladin), Khadgar (Mage) and Kurdran (Gryphon Rider on his mount Sky'ree). The Horde heroes are Grom Hellscream (Grunt), Kargath Bladefist (Grunt), Dentarg (Ogre-Mage), Teron Gorefiend (Death Knight) and Deathwing (Dragon). While regular units of the two armies are balanced (only the spells wielded by spellcasters differ), the heroes have greater distinctions. The Orcish heroes are more powerful than their human counterparts. The heroes are important to the story and may not be killed without resulting in the player's defeat during missions with exception of the final missions in both campaigns, and with the exception of Khadgar in the Human campaign and Teron in Orcish campaign (in 11th mission).

In addition, there is a special track at the end of the disc that incorporates unit voices as well as lyrics to create a comical song entitled "I'm A Medieval Man". The song is a medieval parody or tribute song of the Command & Conquer song "Mechanical Man", which features voices as well alluding to the fact that Warcraft served as a primary competitor in real-time strategy games, the expansion being released only a year after Command and Conquer. Development Following the successful release of the base game, Blizzard planned to focus development resources on StarCraft, their next real-time strategy game. As a result, they contracted the development of
