Like the elephants it contains, you will never forget this update.

Creative Assembly have released a few more pieces of new content for Total War: Rome 2, and leading the charge is a “beautifully-designed African elephant model”, which replaces the generic elephant model currently in the game.
The Epirus faction also have some new extras, such as the ability to recruit Thessalian Cavalry, Royal Peltasts and Illyrian Coastal Levies. Epirus also gets a new Mercenary Indian War Elephant unit that they can hire.
According to Creative Assembly you’ll be able to see these new changes if you face Epirus in battle, or use them yourself if you own the Greek States Culture Pack DLC.
