Stardock has launched "Galactic Civilizations IV: Federations & Empires," an expansion introducing four distinct government types that fundamentally alter gameplay. Previously, the base game offered one governing path; this expansion rebuilds the Government screen around unique resources, core loops, and free hero ships for each new government: Oligarchy, Technocracy, Empire, and Federation. These join the free Colonial Charter available in the accompanying v4.0 update.

"Our goal is that each government type changes the way players play the game," stated Lead Designer Brad Wardell. "Each government has its own special ships, resources, improvements, and more." The expansion also introduces four political parties—Militarists, Progressives, Traditionalists, and Industrialists—whose influence drives in-game events like elections and coups, moving beyond random rolls.

Simultaneously released, the free Version 4.0 update for all "Galactic Civilizations IV" owners adds a Map Editor, custom maps, improved turn notifications, a mini-map, Institutions for leaders, a redesigned Diplomacy & Trade screen, and enhanced AI. "Federations & Empires" is priced at $19.99 with a launch discount until August 6.
