Civilization 7 dataminers have discovered a fourth, unnanounced Atomic Age which could soon be added to the game.

Civilization 7 has a new mechanic, Ages, and a recent datamine suggests a fourth is on the way. In Civilization 7, a new system has replaced the previous Eras of the game. In Civilization 6, there was both a World Era and an Individual Era, with the former being the median of all civilizations in play.

Sid Meier’s Civilization 7 doesn’t officially launch until Feb. 11, but that hasn’t stopped folks from datamining the strategy game during its advanced access period and potentially uncovering future content.

Civilization VII isn't even out officially until tomorrow, 11th February, but Deluxe and Founder's Edition owners have been playing for a few days via early access. Inevitably, this means that PC users have had more than enough time to crack the whole thing wide open.
