After a city has been conquered, it can be: razed, annexed, or transformed into a puppet state. Cities can also fire at sieging units, softening them up for a counterattack. Garrisoning units and building defensive buildings will increase a city's defense rating. All cities possess hit points-if this reaches zero, the city will fall under the attacker's control. Sieges in Civilization V are different from the previous games, as cities are now able to defend themselves. However, they are weak in melee combat and require good positioning or a melee defender to avoid from being destroyed. They can attack units from a distance, allowing them to take potshots at invading armies. Ranged units also make a return to the franchise. Unit stacking from previous games has been removed, replaced with a one military unit-per-tile system. The combat system has been completely overhauled in Civilization V. Players can win through having the highest score, capturing all enemy capitals, being the first to reach Alpha Centauri, winning the United Nations vote, or even being the most culturally affluent of all the civilizations and building the Utopia Project.

Throughout the game, the player will encounter other civilizations, and can form relations and become strong allies, or crush them to smithereens. The game usually begins in the Stone Age, although players can choose a pre-determined age to start off from, and will progress through the ages to the Future Era. In Civilization V, the player chooses a civilization and manages its cities and units, trying to achieve victory. This wikipage is reflective of the mechanics as employed in the base game.
