0 A.D. is a free, open-source, cross-platform real-time strategy game under development by Wildfire Games. It is a historical war and economy game focusing on the years between 500 B.C. and 1 B.C. for the first part, and a planned second part for the years 1 A.D. to 500 A.D. The game is cross-platform, playable on Windows, OS X, Linux, and OpenBSD. The game aims to be entirely free and open-source, using the GPL 2+ license for the game engine and CC BY-SA for the game art.

0 A.D. originally began as a comprehensive total conversion mod concept for Age of Empires II: The Age of Kings in June 2001. With limited design capabilities, the team soon turned to trying to create a full independent game based on their ideas. The game has been in development since 2000, with actual work starting in 2003.

In November 2008, the developers confirmed that they would soon be releasing the project as open-source. On 10 July 2009, Wildfire Games released source code for 0 A.D. under the GPL 2+, and made the art content available under the CC BY-SA.

There were about ten to fifteen people working on 0 A.D. around 23 March 2010, but since development started there have been over 100 people who have contributed.

On 5 September 2013, an Indiegogo crowdfunding campaign was started with a US$160,000 goal. They raised a total of US$33,251 to be used to hire a programmer. The majority of the finances are managed by the Software in the Public Interest organisation.
