The game includes multiple units and buildings specific to each civilization as well as both land and naval units. During the game, the player advances from "village phase", to "town phase", to "city phase". The phases represent the sizes of settlements in history, and every phase unlocks new units, buildings, and technologies. Multiplayer functionality is implemented using peer-to-peer networking, without a central server.

0 A.D. originated in 2001 as a comprehensive total conversion mod concept for Age of Empires II: The Age of Kings. The development team later decided that making the project as a mod was too limiting to their creative freedom, and elected to move their art and ideas to an in-house engine, making it a standalone game. Matei Zaharia was a noted member of the team. The historical accuracy of game elements has been the highest development priority. Unit and building names are shown in the original language of the civilization they belong to, and they are also translated into the language in which the user is playing the game. There is also a strong focus on attempting to provide high visual accuracy of unit armor, weapons, and buildings. On 10 July 2009, Wildfire Games released the source code for 0 A.D. under the GNU GPLv2 (or later) license, and made the artwork available under the CC BY-SA license. There were around ten to fifteen people working on 0 A.D. around 23 March 2010; since development started, over 100 people have contributed to the project. On 5 September 2013, a crowdfunding campaign was started on Indiegogo with a goal. They raised a total of to be used to hire a programmer. The majority of the project's finances are managed by the Software in the Public Interest organization. There is no official release date set for the finished version of the game. • Illustration — Let's Play video of the game (2016) The composers of the music in the game are Omri Lahav, Jeff Willet, Mike Skalandunas, and Shlomi Nogay.
