0 A.D.[a] is a free and open-source, real-time strategy game under development by Wildfire Games. It is a historical war and economy game focusing on the years between 500 BC and 1 BC for the first part, and a planned second part for the years 1 AD to 500 AD.[1][2] The game is cross-platform, playable on Windows, macOS, FreeBSD, Linux, and OpenBSD.[3] It aims to be entirely free and open-source, using the GPLv2+ license for the game engine and CC BY-SA for the game art.

0 A.D. features the real-time strategy gameplay components of building a base, economic development, training an army, combat, and technology research.[4][2] The game includes multiple units and buildings specific to each civilization as well as both land and naval units.[5]

During the game, the player does not advance through time, but from village phase over 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.[6]


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.[7]

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.[8][9]

There were about ten to fifteen people working on 0 A.D. around 23 March 2010, but since development started over 100 people have contributed.[10]

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.[11][12] The majority of the finances are managed by the Software in the Public Interest organisation.

There is no official release date set for the finished version.[13]


For 2010, 0 A.D. received an honorable mention for Player's Choice Upcoming Indie Game of the Year. 0 A.D. has been generally well received.[14] It was voted as LinuxQuestions.org "Open Source Game of the Year for 2013".[15]
