Firaxis has revealed Arc of Tomorrow, a major free update planned for Civilization 7 in 2027. The update will add the Atomic Age as a fourth Age and extend the playable timeline from approximately the 1950s through the 2050s. Firaxis has not announced a specific release date.
The new Age is intended to provide more than a longer endgame. Firaxis says it will bring period-specific gameplay alongside new buildings, units, visuals, and music. New civilizations and leaders are also planned, although their identities will be disclosed later. Players will be able to guide an empire into the Atomic Age from Antiquity or begin there through an Advanced Start.
Nuclear strategy becomes a broader political system
Expanded nuclear gameplay is one of Arc of Tomorrow’s main additions. Firaxis is developing new offensive and defensive options and units, together with what it calls a “fun twist” on mutually assured destruction. The studio has not yet published a complete unit list or detailed balance rules.
The design also includes Multilateral Agreements. These will allow several leaders to react collectively to developing situations, including a growing stockpile of nuclear warheads, with calls for disarmament or escalation. Firaxis presents the system as part of its attempt to represent the tensions and choices associated with the period without reducing the Atomic Age to a simple technology upgrade.
All of those systems remain in development. Firaxis says the timing and details may change while the team works on the update and incorporates player feedback. That qualification applies to the announced mechanics as well as the wider 2027 schedule.
City-States, proxy warfare, and manufactured goods
Arc of Tomorrow will expand the role of City-States. One planned empire-management option will let players turn their own settlements into City-States, providing another way to manage the settlement limit while retaining access to enhanced City-State abilities.
A related Proxy Warfare system is designed around directing attention and resources toward smaller City-State conflicts instead of entering an all-out war between empires. Firaxis has announced the broad purpose of the feature but has not yet provided a complete ruleset.
The economy will gain a Manufactured Goods system based on recipes. Players will combine specific commodities to create more powerful resources, with enriched uranium given as one example. The update will also introduce Great Works of Film. Film crews will search for locations suited to a chosen genre, and the resulting benefits will vary according to the quality of the film they produce.
Firaxis says Arc of Tomorrow is planned to be larger in scope than the Test of Time update released in May. The developer also intends to put the new content through its Firaxis Feature Workshop so community feedback can help shape the systems before their final release.
Earthrise will be Civilization 7’s first paid expansion
The 2027 roadmap also includes Civilization 7: Earthrise, the game’s first paid expansion. According to the 2K Newsroom announcement, Earthrise will explore humanity’s relationship with space and the environment across an entire campaign rather than limiting space activity to a separate final stage.
During the Antiquity and Exploration Ages, players will chart the night sky, build early observatories, and name celestial bodies. Later progress will include orbital missions, the creation of a space agency, and missions across the solar system. 2K says more details about the expansion will be shared in the coming months.
Arc of Tomorrow and Earthrise are separate releases. Arc of Tomorrow is a free update for owners of Civilization 7, while Earthrise is a paid expansion. Both are planned for 2027, but exact dates have not been announced. Firaxis emphasizes that development is still at an early stage, leaving room for the schedule and individual features to change before launch.
