Civilization 7 Unlocks Atomic Age with a Massive Free Update
Firaxis’s free Arc of Tomorrow overhaul for Civilization 7 adds an Atomic Age (1950s–2050s) with new buildings, units, and a nuclear diplomacy system, plus City-State transformations, proxy warfare, and Great Works of Film; a paid Earthrise expansion teases space-focused content. Set for 2027—about two years after launch—Arc of Tomorrow aims to be Civ 7’s biggest overhaul as it struggles with mixed reviews, while the game remains free-to-play on Steam through Sept 10 and Update 1.5.0 is near.
