Civilization 7's biggest free update, Arc of Tomorrow, brings Atomic Age in 2027

Firaxis will take Civilization 7 into the Atomic Age with Arc of Tomorrow, the game's biggest free update yet, arriving in 2027. The update follows patch 1.5.0 and will be trailed by a paid space-race DLC called Earthrise, according to PCGamesN.
The Atomic Age arrives more than two years after Civilization 7's launch, a delay that reflects the game's staggered content rollout. Arc of Tomorrow is positioned as the largest free addition to date, extending the game's timeline past its current eras.
The update's 2027 window and the separate Earthrise DLC suggest Firaxis is treating the Atomic Age as both a free milestone and a commercial hook. The space-race expansion, paid and separate from the free update, points to a post-Atomic Age direction for the strategy title.
Kotaku's report confirms the free update and its 2027 timing but does not detail the Earthrise DLC, so the paid expansion's contents and pricing remain unconfirmed.
The Atomic Age update extends Civilization 7's core timeline for free while a paid space DLC tests whether Firaxis can monetize the game's endgame two years after launch.
