Xenophonia makes several factions in the game speak their respective languages instead of accented English. Originally, the goal was to record new audio to allow each faction in the game to speak the medieval form of their respective language, but this soon proved to be a much too ambitious undertaking. Instead, Xenophonia is a collection of sounds from the translated (localized) versions of Medieval II: Total War. This means that the French speak French, the HRE speaks German, the Italian factions speak Italian, the Russians speak Russian, and the Spanish speak Spanish. In addition, if the Kingdoms expansion is installed, the Aztecs in the original game will speak the Native American accent used in the Kingdoms: Americas campaign. Downloads will be available shortly.
The Holy Roman Imperials speak German.
