Ironclad and Stardock are teaming up once again on the second micro-expansion pack for Sins of a Solar Empire. Dubbed, Sins of a Solar Empire: Diplomacy, the new micro-expansion pack will vastly increase the amount of diplomatic options available to players in the game and help make forging good relations with other empires a major option for would-be galactic conquerors. The beta is due out this Fall with the general release Winter 2010.
GameSpot got a quick preview of Diplomacy and featured it in their blog.
"The studio also made a brief showing of the next Sins of a Solar Empire microexpansion, Diplomacy. Diplomacy will, like the last microexpansion, Entrenchment, sell for $9.95 and will offer new gameplay content to the space strategy game. Diplomacy will add new interfaction diplomacy features and new diplomatic tech-tree options to research, including the ability to form treaties with other alien races and to trade treaties with other races. While Sins of a Solar Empire currently has an excellent space combat system, it doesn't have a way to manage relations with other space races, so the new microexpansion will draw inspiration from the diplomacy system of Galactic Civilizations II. Diplomacy will go into beta this fall and is planned to launch next year."
