Xtreme Legends and Empires
In 2002, an Xtreme Legends (Moushouden in Japan) expansion was first released for the main games, beginning with Dynasty Warriors 3. This expansion features new Musou Modes for the characters in the Other category as well as new stages, weapons, items, and modes. The Xtreme Legends expansion only have the new contents by its own, so players would require the original game disc and use the "Mixjoy" option to access all features. The following games would continue the tradition by having Xtreme Legends expansion, save for Dynasty Warriors 6. New characters were also added through the Xtreme Legends starting with Dynasty Warriors 7.
Beginning on 2004, another expansion line, titled Empires was first released for Dynasty Warriors 4. In Empires, the game would combine the action gameplay of the regular series with strategical and tactial elements from Koei's earlier series Romance of the Three Kingdoms. Unlike the Xtreme Legends, Empires did not require the original game disc to access all of its features as it is considered a unique game of its own. Again, the following games would continue having the Empires expansion, including Dynasty Warriors 6, which did not receive an Xtreme Legends expansion.
