Last week, Creative Assembly discussed the direction of its historical Total War series. This week, the developer teased something new for Total War: Rome 2. And today, the turn-based strategy expert has unveiled Empire Divided as the new DLC heading to its 2013 stalwart. 

Set in 270 AD, Empire Divided visits the Roman Empire as it faces economic collapse and its "gravest crisis yet". With that, it's on you to restore the capital to its former glory (or, you know, run it into the ground) as you assume control of ten different playable factions across five cultures (each with its own cultural and faction-driven traits), negotiate new victory conditions, and handle new campaign features—not least plagues, bandits and cults.
