Exodus of the Horde was used as the game's demo of Warcraft III and called "Prologue". In the retail version of Warcraft III: Reign of Chaos, the last three missions were cut out and just the tutorial levels were left as the "Prologue campaign" — with the Introduction: The Prophecy and Cinematic: Thrall's Vision added — however, it was extended in the official "Custom campaign" in Warcraft III: The Frozen Throne adding the last three missions back. Although the remaining missions were added in the Frozen Throne, the voice acting was removed.
