Tired of "Hollywood-like" battles with modern music?
Do you want to "feel" really ancient battles?
Then Iberia Total War Gold Edition Sound System is your ideal addendum for Iberia Total War Gold Edition.

Features:

1. Eliminated music custom battles, substituted by other sounds (troops movement, silence, war songs, war instruments, orders, swords, voices...).
2. All voices from soldiers are in ancient language voices (latin, greek, aramean, godelic...).
3. Players can listen enemy voices from near enemy troops.
4. Speeches from general before battles in ancient recreation languages.
5. Improved Vanilla sounds like wind, rain, horses, animals, elephants, troops marchings.
6. Added new music to every campaing.
7. New sounds effects for menus.
And much more...

Visit our forums for more information.
Of special interest is the ancient languages + general's speeches in ancient languages.

I though EB might want to incorporate it or look into it.
