Just a few tid-bits i have just finished reading about for the Expansion Pack.

1.The Roman Empire is split into two parts.The Eastern and Western Empires.

2.The Persian Sasanid Dynasty is now a playable faction.

3.Attila the Hun and his merry men will start the campaign with 15 full armies and no settlements.They have the ability to recruit mercs and re-inforcements for plunder(sounds like the Mongols in Shogun)

4.The Saxons will specialize in coastal landing and raiding by sea.

5. The Vandals are a playable faction......no info on them.

6. The Roman Empire(both halves) are huge but rebellious and in dire straits.

7.Light troops including cavalry can now swim across rivers on the battle-field making it possible to flank units guarding a bridge.

8.Night battles are now options for experienced commanders and affect morale accordingly.

9.Composite bows available with a longer range and armour piercing early model of the x-bow.

10.Many new units and formations(couple of fantasy units as well unfortunately).
