The next DLC update for Total War: Rome 2, Wrath of Sparta, will be released on December 18 and if you pre-order the content, you can take 10% off.
You have until December 16 to take advantage of the offer.
Set during the outset of the Peloponnesian War, the Wrath of Sparta expansion is rather large, as you can see via the Steam page, and is the “earliest period that Total War has ever attempted.”
The pack features all new tech-trees, battlefield and naval units, wonders, and famous Greek heroes along with athletic competitions and festivals.
