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 twelve 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, 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.

0 A.D. is being developed by Wildfire Games, a community of volunteer, hobbyist game developers from all over the world. 0 A.D. has been an open source project since July 2009. We're looking for programmers, 3d artists and more.

Wildfire Games, an international group of volunteer game developers, proudly announces the release of“0 A.D. Alpha 19 Syllepsis”, the nineteenth alpha version of 0 A.D., a free, open-source game of ancient warfare. This alpha features building and siege engine capture, a new pathfinder, visual replay and more!

Easy Download and Install

Download and installation instructions are available for Windows, Linux and Mac OS X. 0 A.D. is free of charge and always will be. Although you might find some people selling copies of 0 A.D., either over the internet or on physical media, you will always have the option to download 0 A.D. completely gratis, directly from the developers.



Moreover, you can redistribute the game and modify it freely as long as you abide by the GPL. You can even use parts of the art and sound for your own projects as long as you abide by CC BY-SA. No “freemium” model, no in-game advertising, no catch.

New Gameplay Features in This Release

  • Building and Siege Engine Capture: Non-siege units can now capture buildings and siege engines. When you hover your mouse over an entity that can be captured, two crossed flags appear so you can issue a “capture” order. If you do, you will start gaining some of that entity’s “capture points” at a certain rate. (On screen, you will see your color taking up a greater proportion of the width of the entity’s capture bar.) Once you gain all of these points, you capture the entity, and it is yours! (Note: You can still specify a regular attack on buildings and siege engines by holding CTRL when right-clicking on a target.) There is currently no animation for the units which are capturing, that will be added in a later version.
  • New Victory Modes: “Conquest Structures” (destroy or capture all enemy structures to win) and “Conquest Units” (destroy all enemy units to win).
  • Ceasefire Game Mode: The game can be set so that all players are completely unable to attack their enemies for a predetermined time at the start of a game.
  • Attack Coordination: Players can request allies (including bots) to attack a specific enemy by clicking a button next to the player name in the diplomacy window. Also, Petra AI now supports attack coordination.
  • Petra AI now warns its allies when it needs a tribute and lets them know when it advances to a new phase.
  • The Ptolemaic lighthouse now has its special feature implemented: It reveals the shore on the entire map.
  • New Skirmish Maps: Tuscan Acropolis (for 4 players; map preview), Northern Island (for 2 players;map preview), and Alpine Mountains (for 3 players; map preview).

Preview of the new skirmish maps added in Alpha 19

Graphics and User Interface

  • Increased Maximum Map Height: The engine now supports an eight times greater range of terrain heights, allowing for the creation of maps with more diverse and impressive landscapes.
  • Visual Replay: Re-run a game and understand what took place in real time.
  • Aura Visualization: Units affected by an aura are now marked with an icon when the aura giver is selected.
  • New animals: New mastiff and wolfhound units have been added as well as a new rhinoceros.
  • The Roman units now have voices in Latin. Voice actors and people with knowledge in ancient languages are invited to contribute more voices to the game!

Under the Hood

  • New Pathfinder: The pathfinder is the component of the game engine that picks a route for a unit to move along from its current location to its target location, so that it does not collide with other units or with structures or with impassable terrain. The new pathfinder improves performance, but at the same time, it also introduces some new bugs. We have done as much as we could to ensure it was bug-free, but please report anything unusual!
  • XML Validation: In 0 A.D., the behavior of units, buildings and other world objects is defined by their components, such as cost, health and more. All of these are described in XML files. The “grammar” of the XML files is now checked for correctness before being used by the game engine, which helps prevent technical problems.
  • The generic Hellenic and Celtic factions have been removed.
  • Linux users, please be advised that SDL2 is now enabled by default on Linux.

Getting Support

Please see the “Get Support” page on our website to find ways to get help from the active and friendly 0 A.D. community.

We are well aware there is some room for improvement in 0 A.D. Some known issues are: Lag, visual glitches or textures not loaded, missing animations and more. When you provide feedback, we would ask you to focus on some of the other points that could be improved. Thanks.

Please Contribute!

We are seeking volunteer contributors in programming, art, sound, documentation and more. Programmers are especially welcome and can get started immediately.

Interested? Log onto #0ad-dev on QuakeNet on IRC and meet the developers. Also, you are invited toregister on our forums and start participating!

Why “Syllepsis”?

We name our releases according to development status (“Alpha” or “Beta”), successive release number (1, 2, 3, …) and a word relating to the ancient world, in alphabetical order (“Argonaut” for A, “Bellerophon” for B, …).

“Syllepsis” relates to 0 A.D. as it means “capture” in Greek, and refers to the building and siege engine capture feature implemented in this version (Thanks, bouke!).

For the next alpha, we welcome fan suggestions for words relating to the ancient world beginning with the letter T. Keep it original and related to the time frame portrayed in 0 A.D. (appx. 500 BC – 1 BC)!

The game is amazing, however, the let down would be that resource, such as wood, is highly demand then most other RTS games, in fact, most the time would be spent gathering food. Another issue would be the map editor and its limitation, and tutorial for beginners. Overall the game receive good recommendation from me, since it is in alpha, and will have my support, however, it would be great to fix some parts.

Increase wood source or decrease wood cost.

In what area is the map editor limited? I've created several awesome maps with it (Northern Islands comes from my hands f.e.)

Well this one depends, not alot of guides to work with on map editor, it limits me on how to actually know which part is which, but its not that big of an issue unlike alot of parts.

This game need to fix in this area-

-Formations are terrible, lack of proper coding, makes them run up and down while being attacked, until most unit dies, it fights back.
-Path finding is still hard to work around with.
-Units are unevenly balanced, specials within factions are off.
-Wood is a high pain, resource are very lacking, require less cost or more deposit.
-AI require a more better strategy.
-AI rushes instantly without failing to notice them being stuck.
-Walls are useless, archer ontop can only shoot infront, they are very vulnerable to enemy range.
-palisade are useless, most wood would go to units instead of weak walls.
-low amount of different unit types, leads gaps in some faction strategical outtake.
-AI barely builds ships.
-controls must be better worked, annoyed how we had to always capture their siege. Capture should be a separate button.
-Javelin units are under powered compare to bows.
-terrain fix, enemy scale cliffs somehow.
-AI spam towers all over the place.

I love this game. Just started playing it and i already went to multiplayer. I hope this game stays free to play. Wouldn't have money to pay for it. :v
But the only problem about multiplayer is that there is too much lag. It's barely playable(only mp, sp works perfectly) :)
Keep up with this game, love you <3

It would also be cool if like in Stronghold 2 you could move your guys on the wall.

It should already be possible using the garrison command. :)

It would be cool if units switched their weapons like AOE3. Like a bowman has a backup sword.
