Civilization 5's next expansion, Brave New World, will launch in North America July 9, and will see an international release July 12, Firaxis announced today during its PAX East 2013 panel.

The game's add-on was demonstrated during the panel, showing off the new World Congress, which is geared for diplomacy, as was the game's new civilization, the Polish Empire. The expansion will add other new features to the game as well, including new paths to a Cultural victory, eight new wonders, new trade systems and two new scenarios.

Check out our recent interview with Firaxis for more information on the expansion.
