Civilization VII's Arc of Tomorrow free update arrives in 2027, dragging the timeline from the 1950s into the near future with a new Atomic Age and a reworked take on nuclear annihilation that actually tries to make MAD feel like more than a science victory shortcut. Firaxis promises updated tech trees, new units including helicopters, manufactured goods like enriched uranium, Great Works of Film mechanics, and the return of Gandhi as a leader while introducing a one-turn delay on nuclear launches so defenders get a shot at retaliation or countermeasures. The real twist comes in the revived loyalty system that lets empires splinter settlements into city-states for proxy wars, turning late-game stalemates into layers of shadow conflict instead of one big button press toward oblivion.
