Stardock today announced that Galactic Civilizations II: Twilight of the Arnor has gone into final testing. The expansion pack to the space strategy game, Galactic Civilizations II: Dread Lords, completes the Dread Lord saga with the return of the Precursor civilization, the Arnor. Arguably the most comprehensive expansion pack in strategy game history, Twilight of the Arnor has more new features and content than Galactic Civilizations II had over the original.

Among the new features are unique technology trees for each of the 12 major civilizations. This also means unique weapons, ships and planetary improvements for each civilization. Moreover, a new victory condition has been added called Ascension in which players can take control of the Ascension crystals (introduced in the campaign) for victory. In addition, the graphics of Twilight of the Arnor have been revamped to bring the game’s visuals to 2008 standards.

Stardock has set April 30 as the lauch date for the digital release. Twilight of the Arnor does require the first expansion pack, Dark Avatar, to run. A bundle of the entire saga is available at a discount.
