Civilization 7 adds Atomic Age in free 2027 update

At a Pax West 2026 panel marking 35 years of Sid Meier’s Civilization, Firaxis announced three planned releases for Civilization 7: patch 1.5.0 in September 2026, a free Arc of Tomorrow update in 2027 and a paid Earthrise expansion expected in 2027.

Patch 1.5.0 will add several quality-of-life changes and a True Start Earth map option that places each civilization in historically accurate locations and positions Natural Wonders in their proper regions. Firaxis said the game will randomly vary which Natural Wonders appear each match. The September update will also use the studio’s Voronoi map-generation algorithm on two additional maps, Terra Incognita and Shuffle, and will speed up map loading and generation while increasing resource placement variety.

The update will refine diplomacy and game setup. Leaders will be able to use Influence to remain allied without being obliged to join allies’ wars. Firaxis will revise tooltips, settlement banners and the game setup screen and add a tile ruler to help city planning.

Arc of Tomorrow is a free content update scheduled for 2027 that introduces Civilization 7’s fourth Age, the Atomic Age. The update extends the playable timeline roughly a century beyond the current mid-20th-century endpoint and will add new civilizations, leaders, buildings, units and gameplay systems.

Firaxis said the Atomic Age will expand nuclear options for offensive and defensive play and will include mechanics for multilateral agreements, allowing multiple leaders to act together on issues such as disarmament or escalation. Settlements will be able to transform into city-states with enhanced interactions. A proxy warfare system will provide alternatives to full empire-wide conflict. The update will add a Manufactured Goods mechanic to combine commodities into powerful resources, with Enriched Uranium given as an example, and will expand cultural content to include Great Works of Film.

Earthrise, the title of the first paid Civilization 7 expansion, will focus on the historic space race and missions across the solar system. Firaxis said players will be able to chart and name celestial bodies as early as the Antiquity or Exploration Ages. Reaching the Modern Age will unlock early orbital missions around Earth and the Moon. In the Atomic Age, players can establish national space agencies, launch missions across the solar system and discover planetary features and resources that can affect a civilization’s development at home. Firaxis said Earthrise will not be a full science-fiction conversion of the game.

Firaxis noted the True Start Earth option aims for historical accuracy at the expense of traditional multiplayer balance, since real-world geography can advantage some civilizations. The studio said it will keep familiar maps feeling fresh by varying Natural Wonders between games.

Creative Director Ed Beach closed the panel with a message of thanks: “35 years of ‘one more turn’ memories is a tremendous milestone. On behalf of the team at Firaxis Games, thank you for being a part of Civilization, and for making all of this possible.”

Earlier in 2026 Firaxis deployed the Test of Time rework, which redesigned many systems in Civilization 7. Arc of Tomorrow will continue that expansion of the game’s scope, and Earthrise will be the franchise’s first paid Civilization 7 expansion with major official space-themed mechanics.
