Civilization 7 is set to significantly expand its gameplay scope in 2027 with the free "Arc of Tomorrow" update, which will push the game's timeline into the atomic age and beyond. Firaxis announced that this update will be "even bigger in scope" than the previous "Test of Time" overhaul, introducing a fourth Act that extends the game's playable years from 1950 to 2050. This significant expansion will bring new features and strategic opportunities, including an "expanded nuclear gameplay" system featuring new units and a novel approach to mutually assured destruction. Players will also gain access to new atomic-era diplomacy options, allowing for calls for nuclear disarmament or escalating conflicts towards a doomsday scenario.
Beyond nuclear warfare, "Arc of Tomorrow" will also introduce mechanics for transforming settlements into City States, enabling proxy wars and Cold War-style conflicts without direct engagement between major empires. The update will also add the capability to manufacture advanced resources like enriched uranium and introduce a "Great Works of Film" system, where film crews can scout global locations for cultural benefits.
Alongside "Arc of Tomorrow," Firaxis also revealed details about Civilization 7's first major expansion, "Earthrise," which is slated for release in 2027. This expansion will focus on humanity's venture into space, integrating stellar exploration throughout the game rather than confining it to an end-game Space Age. Players will be able to chart the night sky from antiquity, name celestial bodies, launch orbital missions in the modern era, and establish their own space agencies for solar system exploration.
Both the "Arc of Tomorrow" free update and the "Earthrise" expansion are planned for release in 2027, though Firaxis noted that announced features are still in development and subject to change. Currently, Civilization 7 is available to play for free until September 10, with the full game offered at a 50% discount until September 17, reducing its price to $35 (£30) from its original $70 (£60).
