Features
Empire: Total War will feature a new game engine as well as 3D naval battles, a feature new to the series, as well as large land battles with muskets, cavalry and artillery. Buildings and structures can be garrisoned, as well as being destructible, and there is a plethora of new formations and strategies to be mastered. The naval battles feature destructible sails, realistic cannon fire, grapeshots and boarding action. Weather effects are also a key chapter in naval battles.

The battles on land have been given a makeover too:

* The firing of cannons, arrows and muskets is made more realistic.
* Music makes its way into the battlefield in the form of bagpipes, drums, fifes and trumpets.
* Weapons may jam and misfire, and cannons can explode.
* Generals shout orders at their troops as the regiment goes into combat or fires at enemies.
* The battlefield becomes strewn with dead, dying and dismembered bodies. The game makes use of ragdoll physics to add to the chaos.

A full list of confirmed features can be found in the frequently updated TotalWar.org forum summary thread.
