Galactic Civilizations II: Twilight of the Arnor is a 2008 turn-based strategy expansion for PC, developed by Stardock as the second add-on to Galactic Civilizations II: Dread Lords. The expansion introduces Terror Stars, enormous vessels capable of destroying entire solar systems, alongside a significant overhaul to civilization differentiation — each faction now has its own distinct technology tree, planetary improvements, and weapons rather than sharing a common research path. A map pointer and custom scenario editor give players greater control over how games are constructed and played. On the technical side, new graphics reduce memory requirements by more than 90% compared to previous versions. The expansion also adds an exceptionally large map size designed to support campaigns of such scale that they may span millennia of in-game time before reaching a conclusion.
