Firaxis has described the upcoming free update as "even bigger in scope" than May's Test of Time patch. That's a significant claim given Test of Time was the largest single update Civ 7 had received since launch, and it still only nudged the game's Steam rating to 51% positive.
Sid Meier's Civilization VII is about to get a lot more explosive. The studio announced Arc of Tomorrow, a free update targeting a 2027 release window that extends the game's timeline from 1950 all the way to 2050, adding a fourth Act and finally bringing nuclear submarines, ICBMs, and Cold War-era diplomacy into the fold.
What the current game is missing
Here's the thing: Civ 7 at launch already let players drop atom bombs via World War 2-era bombers. But the game's modern age hard-stops at 1950, which means the entire Cold War arms race, nuclear deterrence, and late 20th-century geopolitics simply don't exist. For a series that built its reputation on letting players race from stone tools to space stations, that felt like a conspicuous gap.
Test of Time addressed a lot of structural complaints, bringing mechanical reworks and a fresh wave of players back to the game. The problem is that even after that overhaul, the missing late-game content remained a sticking point for players who wanted to see their civilizations survive into the modern era.
Arc of Tomorrow: what Firaxis is adding
The fourth Act introduced by Arc of Tomorrow covers a full century of history from 1950 to 2050. The headlining addition is expanded nuclear gameplay, which brings new unit types and what Firaxis is calling a "fun twist" on mutually assured destruction. Atomic-era diplomacy options will let players push for nuclear disarmament treaties or escalate warhead production and watch the in-game doomsday clock creep toward midnight.
Beyond the bombs, the update introduces a system for transforming settlements into City States and using them as proxies in conflicts, effectively letting players fight Cold War-style shadow wars without direct empire-to-empire confrontation. There's also a resource manufacturing system for materials like enriched uranium, and a "Great Works of Film" mechanic where film crews travel the world scouting locations for cultural gains.
The Earthrise expansion arrives alongside it
Arc of Tomorrow won't be landing alone. Earthrise, Civ 7's first major paid expansion, is targeting the same 2027 window. The expansion focuses on space exploration, and what makes it interesting is that it doesn't confine the space race to a single end-game era. Players can chart the night sky and name celestial bodies as early as antiquity, launch first orbital missions in the modern age, and eventually build out a full space agency to venture into the solar system.
That design choice, threading space exploration across the entire game rather than bolting it onto the final act, is one of the more structurally ambitious things Firaxis has announced for Civ 7 so far.
Where Civ 7 stands right now
The update announcement dropped alongside the release of update 1.5.0, which adds improved resource generation and a historically accurate Earth map where factions start at their real-world locations. For players who've been tracking the game's evolution through patches, our Civilization VII update 1.4.1 patch rundown covers what the previous major update changed, including the reworked Governments system. If you want to get up to speed on how those government changes actually play out, the Civ 7 governments explained guide breaks it all down.
The base game is currently free to play through September 10, and the full game is 50% off at $35 until September 17. That's a reasonable entry point if you want to see whether Civ 7's age-based structure works for you before Arc of Tomorrow and Earthrise arrive next year.
Firaxis has noted that all announced features are still in development and subject to change, so the specifics of the nuclear gameplay twist and the Earthrise space systems could look different by the time 2027 rolls around. What's clear is that the studio is committed to a significantly larger update than anything Civ 7 has seen before, and for a game that's been fighting perception problems since day one, that ambition is probably the right call.
