[[TOC]] Part of the [wiki:0adManual 0 A.D. Gameplay Manual] = Quickstart Guide - if you've played other RTS games = This guide aims to give you the basic facts you need to get into playing without boring you with the details and concepts which are the same in all RTS games. If this guide doesn't give you the answer you're looking for you might want to read through the [wiki:Manual_BasicGameplay Basic Gameplay] page, or another of the pages in the [wiki:0adManual manual]. == Citizen Soldiers == The main difference is that some units have the dual role of being both workers and soldiers. They are called Citizen Soldier and are the most basic soldiers, a few of them can be built from the Civic Centre (comparable to a Town Center in Age of Empires etc) and the rest from the Barracks. == Resource Dropsites == 0 A.D. uses resource dropsites, like the original Age of Empires games and Empire Earth. == Damage Types == Damage in 0 A.D. comes in three types: hack, pierce and crush. Units have different armour for each type. In addition, unit attacks may be of multiple types simultaneously (e.g. a Hoplite does both pierce and hack damage). Therefore, you may see some units do different amounts of damage to different enemies.
