Two new Civilization V DLC packs will be released on Thursday, 11th August.
They are the Civlization and Scenario Pack: Korea, and the Wonders of the Ancient World Scenario Pack.
The former involves Korea, China, Manchuria and Japan. You can play as any of those factions and plot your part in history after Toyotomi Hideyoshi unifies Japan. You can even fill the boots of Korean leader Sejong, King of the Chosen Dynasty.
Wonders of the Ancient World brings three new wonders to the game: the Mausoleum of Halicarnassus (boosts economy), the Statue of Zeus (boosts siege power when attacking cities) and the Temple of Artemis (makes cities grow faster). The scenario involves building all nine ancient wonders first - or taking them by force from local rivals.
You can buy each pack separately for $4.99; alternatively, you can buy them together for $7.49.
Incidentally, there's a patch on its way to Civilization 5, but "not necessarily releasing before this DLC", wrote 2K Games community manager 2K Greg on the game's forum.
Civilization 5 was released in September 2010. Eurogamer's Civilization 5 review awarded 8/10.
