0 A. D.
0 A.D.[a] is a free and open-source real-time strategy video game under development by Wildfire Games. It is a historical war and economy game focusing on the years between 500 BC and 1 BC, with the years between 1 AD and 500 AD planned to be developed in the future.[2][3] The game is cross-platform, playable on Windows, macOS, Linux, FreeBSD, and OpenBSD.[4] It is composed entirely of free software and free media, using the GNU GPLv2 (or later) license for the game engine source code, and the CC BY-SA license for the game art and music.[5][6]
0 A. D.
0 A.D. features the traditional real-time strategy gameplay components of building a base, developing an economy, training an army, engaging in combat, and researching new technologies.[7][3] The game includes multiple units and buildings specific to each civilization as well as both land and naval units.[8]
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.
0 A.D. originally began in 2001 as a comprehensive total conversion mod concept for Age of Empires II: The Age of Kings.[10] 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.[11]
The historical accuracy of the 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 a high visual accuracy of unit armor, weapons, and buildings.[10]
There were around ten to fifteen people working on 0 A.D. around 23 March 2010; but since development started, over 100 people have contributed to the project.[12] 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.[13][14] The majority of the project's finances are managed by the Software in the Public Interest organisation. There is no official release date set for the finished version of the game.[15]
In 2012, 0 A.D. received second place in the IndieDB Player's Choice Upcoming Indie Game of the Year competition.[17] 0 A.D. has been generally well received.[18] It was voted as LinuxQuestions.org "Open Source Game of the Year for 2013".[19] Between 2010 and June 2021, the game was downloaded from SourceForge.net over 1.3 million times.[20]
A year zero does not exist in the Anno Domini (AD) calendar year system commonly used to number years in the Gregorian calendar (nor in its predecessor, the Julian calendar); in this system, the year 1 BC is followed directly by year AD 1. However, there is a year zero in both the astronomical year numbering system (where it coincides with the Julian year 1 BC), and the ISO 8601:2004 system, the interchange standard for all calendar numbering systems (where year zero coincides with the Gregorian year 1 BC; see conversion table). There is also a year zero in most Buddhist and Hindu calendars.
Previous Christian histories used several titles for dating events: anno mundi ("in the year of the world") beginning on the purported first day of creation; or anno Adami ("in the year of Adam") beginning at the creation of Adam five days later (or the sixth day of creation according to the Genesis creation narrative) as used by Africanus; or anno Abrahami ("in the year of Abraham") beginning 3,412 years after Creation according to the Septuagint, used by Eusebius of Caesarea; all of which assigned "one" to the year beginning at Creation, or the creation of Adam, or the birth of Abraham, respectively. Bede continued this earlier tradition relative to the AD era.[citation needed]
Neither the concept of nor a symbol for zero existed in the system of Roman numerals. The Babylonian system of the BC era had used the idea of "nothingness" without considering it a number, and the Romans enumerated in much the same way. Wherever a modern zero would have been used, Bede and Dionysius Exiguus did use Latin number words, or the word nulla (meaning "nothing") alongside Roman numerals.[1][4][5] Zero was invented in India in the sixth century, and was either transferred or reinvented by the Arabs by about the eighth century. The Arabic numeral for zero (0) did not enter Europe until the thirteenth century. Even then, it was known only to very few, and only entered widespread use in Europe by the seventeenth century.[citation needed]
The anno Domini nomenclature was not widely used in Western Europe until the 9th century, and the 1 January to 31 December historical year was not uniform throughout Western Europe until 1752. The first extensive use (hundreds of times) of 'BC' occurred in Fasciculus Temporum by Werner Rolevinck in 1474, alongside years of the world (anno mundi).[6] The terms anno Domini, Dionysian era, Christian era, vulgar era, and common era were used interchangeably between the Renaissance and the 19th century, at least in Latin. But vulgar era fell out of use in English at the beginning of the 20th century after vulgar acquired the meaning of "offensively coarse", replacing its original meaning of "common" or "ordinary". Consequently, historians regard all these eras as equal.[citation needed]
Historians have never included a year zero. This means that between, for example, 1 January 500 BC and 1 January AD 500, there are 999 years: 500 years BC, and 499 years AD preceding 500. In common usage anno Domini 1 is preceded by the year 1 BC, without an intervening year zero.[7] Neither the choice of calendar system (whether Julian or Gregorian) nor the name of the era (Anno Domini or Common Era) determines whether a year zero will be used. If writers do not use the convention of their group (historians or astronomers), they must explicitly state whether they include a year 0 in their count of years, otherwise their historical dates will be misunderstood.[8]
Finally, in 1740, the transition was completed by French astronomer Jacques Cassini (Cassini II), who is traditionally credited with inventing year zero.[12] In his Tables astronomiques, Cassini labeled the year simply as 0, and placed it at the end of years labeled avant Jesus-Christ (BC), and immediately before years labeled après Jesus-Christ (AD).[13]
Attention! This is an early version of the game so bugs, such as lag when many units are moving or lag issues with very large maps, may exist.However The game is updated regularly to mitigate those concerns.//
The next alpha of 0 A.D. will feature an experimental Vulkan backend!You can test it and report bugs by downloading the development version of the game.More information here: -vulkan-new-graphics-api/#comments
Wildfire Games is an international community of dozens of game developers and gamers, who mostly contribute in their spare time on a volunteer basis. We strive to create strategy games as great as the classics of the genre, and to contribute to its evolution.
For the last few years, we have been exclusively developing "0 A.D.", a free, open-source strategy game of ancient warfare, set for release on Windows, GNU/Linux and the Mac. It's a tribute to the ancient world, from Greece and Rome to Carthage and India, with its first edition focusing on the five centuries following 500 B.C. It is powered by our custom-made, powerful and free engine, named "Pyrogenesis".
Another notable project we once made is a total conversion mod for "Age of Empires II: The Age of Kings", named "Rome at War". Released in 2001, it remains one of the top mods for this classic strategy game.
We work within an organized structure (more). We are always looking for skilled programmers and other types of contributors. We invite you to head to our forums and join our active community, and to say hello on our IRC channels, #0ad and #0ad-dev on QuakeNet. Please feel welcome!

0 A.D. (pronounced "zero ey-dee") is a free, open-source, cross-platform real-time strategy (RTS) game of ancient warfare. It's a historically-based war/economy game that allows players to relive or rewrite the history of twelve ancient civilizations, each depicted at their peak of economic growth and military prowess.
The fourteen factions are: Three of the Hellenic States (Athens, Sparta and Macedonia), two of the kingdoms of Alexander the Great's successors (Seleucids and Ptolemaic Egyptians), two Celtic tribes (Britons and Gauls), the Republican Romans, the Achaemenid Persians, the Iberians, the Carthaginians, The Hans, The Kushite and the Mauryan Indians. Each civilization is complete with substantially unique artwork, technologies and civilization bonuses.
Developed using Pyrogenesis, a game engine custom-built to suit our needs, 0 A.D. will give players a rich and entertaining real-time gaming experience. 0 A.D. is portable, running not only on Windows, like most games, but also on Linux and Mac OS X.
We believe free, OS software like 0 A.D. encourages sharing, learning and creativity. That's why we have made the code and data available under the GPL license, and released the art, sound and documentation under CC-BY-SA. Modifying the game's data files is as simple as editing JavaScript and XML files, so anyone can learn how the game was developed and share their own contribution to the 0 A.D. world. 041b061a72
