A downloadable game for Windows, macOS, and Linux

0 A.D. (pronounced “zero-ey-dee”) is a free, open-source, historical Real Time Strategy (RTS) game currently under development by Wildfire Games, a global group of volunteer game developers. As the leader of an ancient civilization, you must gather the resources you need to raise a military force and dominate your enemies.

History is Yours for the Taking

 “0 A.D.” is a time period that never actually existed: In the usual calendar, one goes from 1 B.C. to 1 A.D. and skips zero. This reflects the historical fiction in the game: Who would have won if all the factions were pitted against each other when each of them was at its prime?

We intend to portray some of the major civilizations over the millennium of 500 B.C. to 500 A.D. (Hence the midpoint, zero.) That is an ambitious prospect, so in the first edition of 0 A.D. we focus on the last five centuries B.C. Perhaps in future expansion packs, more civilizations will be added, along with additional gameplay features.

We put a strong emphasis on historical accuracy while developing 0 A.D. We plan all our units and all our buildings based on reconstructions of how the units and the buildings might have looked like in the ancient world. We even name them in the original languages, such as Greek and Latin. But it’s worth remembering that any game should be fun to play, so, in many cases, we preferred playability over historical accuracy.

0 A.D. is Free of Charge

0 A.D. is completely downloadable at no cost and always will be. No “freemium” model, no in-game advertising, no catch. This is our iron-clad guarantee.

Although you might find some people selling copies of 0 A.D. on physical media, remember, you will always have the option to download 0 A.D. gratis on the internet, directly from the developers.

0 A.D. is Free as in “Freedom”

0 A.D. is freely licensed software, because we believe everyone should have access to great games, and that everyone can learn from developing them. You can redistribute and modify the game as long as you abide by the GPL. And you can even use parts of the art and sound for your own projects as long as you abide by CC BY-SA.

0 A.D. is Still Under Development

Work on 0 A.D. began in 2001, first as a mod concept for Age of Empires II: The Age of Kings. In 2003 development moved to a standalone game with its own engine, Pyrogenesis. In 2009-2010, the game was released as free, open-source software and and much of the codebase was rewritten. Learn more about the story of 0 A.D. »

Currently, 0 A.D. is still in alpha phase, which means an early experimental phase. It is playable, and you can already download and test the game, but some features are still missing. When will 0 A.D. be released? It is very hard to predict. Even after we are done implementing all the features, we will want to conduct extensive beta testing, which can take a while. Information about release dates will be released at the appropriate time.

Gioco semplicemente FAVOLOSO e GRATUITO !!!

Hello! First of all, thanks so much for being here. I remember the times I discovered 0 A.D. years ago thanks to CD-Action magazine giving it on CD as “freemium games collection”. Loved it instantly! So I’m very happy to rediscover it and see that the game is more beautiful than ever! And even there are mods for it, this is amazing. I have a question for you, though: is there any plans for expanding economical aspects of the game? I ask especially because I know it’s focused on fight, so I should not expect another Emperor: Rise of the Middle Kingdom, but in the same time, I feel like some additions of aesthetical builds/optional economical path would make this game perfect for all types of strategy players. I started “infinite no-AI” game to relearn things and if I have to be honest, it was a lot of joy just to build beautiful stuff around.


minimun requiriments?

Should be pretty low

Look out Sid Meiers Civilization! A competitor has entered the field!

Downloaded the win file through Itch app and ran the installer. It says error opening file for writing. Whats the issue here?

Maybe your computer is 64-bit? Cos the file says 32-bit

Very good looking game. It's a lot like Rise of nations.

Will the .exe be returned anytime soon? No matter which download button I hit it shows its downloading the .dmg file.


Thanks for the report should be fixed now.

Thank you so much!

omg iamsoo bored waiting for this to install but after reading the comments i think it will be a great game. 


Made a video about this game

What are the system requirements? since I have an potato of a laptop

See https://play0ad.com/download/

But it runs on a lot of different hardware. Expect lags on games with lots of units moving.

looks great but 845MB is

Well there are a lot of assets. Most AAA games are a few dozen GB.

True it's kinda small for how good looking it is

Really great game, it's interesting to see it evolve over the years. I'm glad developers are still working on it. This game deserves to be more popular!

not playable because there is no exe to start

We uploaded an exe to itch.io so you should be able to download that. The default download links on our webpage do link to a torrent file but you can also download directly from releases.wildfiregames.com

Is the reason there is no Linux version on Itch because most distro repos have it already ?

I suppose, we should have an appimage, although I'm not quite sure how to provide one. Currenlty you have to download the two archives and compile them yourself as there are too many distri butions

I can both understand your reasoning as well as offer no idea on how to  provide an app image.  I see there are a flatpack and an app image on the 0 A.D. website, would they not be able to be uploaded to Itch ?

We don't maitain the flatpack so it's a bit complicated to ensure the security, same for the appimage which is also A23B. hence the disclaimer :)
