Features:

EXPANSIVE EMPIRES

See the marvels of your empire spread across the map like never before. Each city spans multiple tiles so you can custom build your cities to take full advantage of the local terrain.

ACTIVE RESEARCH

Unlock boosts that speed your civilization’s progress through history. To advance more quickly, use your units to actively explore, develop your environment, and discover new cultures.

DYNAMIC DIPLOMACY
Interactions with other civilizations change over the course of the game, from primitive first interactions where conflict is a fact of life, to late game alliances and negotiations.

COMBINED ARMS
Expanding on the “one unit per tile” design, support units can now be embedded with other units, like anti-tank support with infantry, or a warrior with settlers. Similar units can also be combined to form powerful “Corps” units.

As with other games in the series, the goal for the player is to lead their fledgling civilization from an early settlement through many millennia to become a world power and achieve one of several victory conditions, such as through military power, technological superiority, diplomatic leadership, or cultural influence, over the other human and computer controlled opponents.Players do this by exploring the world, founding new cities, building city improvements, deploying military troops to attack and defend from others, researching new technologies and cultural civics, and engaging in trade and negotiations with other world leaders.
