Evil has survived. Diablo, the Lord of Terror, now seeks to free his demonic brothers. The armies of Heaven are forbidden to interfere with his plan, so an Amazon, a Barbarian, a Necromancer, a Paladin and a Sorceresses join the battle.

Evil has survived. Diablo, the Lord of Terror, now seeks to free his demonic brothers. The armies of the High Heavens are forbidden to interfere with Diablo's plan. Again, it is up to a single mortal to stand in Diablo's path, to prevent the Three Prime Evils from reuniting. If that mortal fails, the world of Sanctuary will become a permanent outpost of the Burning Hells.—Chris

The world is torn by war being made by Diablo, the demonic lord of terror from Hell itself. With his brothers, the Satanic manifestations Mephisto and Baal, Diablo wages war on the mortal world. However, holy warriors and rebels, along with the help of a celestial Archangel sent by Heaven, stand against Diablo and his malignant forces as they prepare to fight in the truly apocalyptic conflict. In the expansion, Baal takes over command of Diablo's forces as the end of the war draws near.—Flotis

The Lord of Terror is back! Diablo has taken over the hero who managed to defeat him, and is on a quest to release his brothers, Mephisto, Lord of Hatred, and Baal, Lord of Destruction. You choose from seven heroes to go after Diablo and destroy him once and for all. Through the course of the game you are taken to the ruins of Tristram, destroyed by Diablo, to the deserts of Lut Gholein, and down into the bowels of Hell itself. Aided only by the last Horodrim, Deckard Kain, and a benevolent Acrchgangel, Tyrael, you must find and destroy Baal, Mephisto and Diablo's soul stones and lock them in the bowels of Hell forever. In the expansion, Baal, escapes to Mount Arreat, where the Worldstone, the Heart of the world is kept. He is trying to corrupt it for his own purposes, you have to stop him, and send him to hell with his brothers.—Anonymous
