Developer’s description: 0 A.D. Alpha 14 – A free, open-source, cross-platform RTS game.

0 A.D. (pronounced "zero ey-dee") is a free, open-source, cross-platform real-time strategy (RTS) game of ancient warfare. In short, it is a historically-based war/economy game that allows players to relive or rewrite the history of Western civilizations, focusing on the years between 500 B.C. and 500 A.D. The project is highly ambitious, involving state-of-the-art 3D graphics, detailed artwork, sound, and a flexible and powerful custom-built game engine.You can find all downloads (including those for Mac and Linux) HERE.The game has been in development by Wildfire Games (WFG), a group of volunteer, hobbyist game developers, since 2001. The code and data are available under the GPL license, and the art, sound and documentation are available under CC-BY-SA. In short, we consider 0 A.D. an an educational celebration of game development and ancient history.Top features – TechnicalThe engine core is written in C++ for performance, but the scripting language, javascript, is what we try to write as much in as possible.Rendering: OpenGL with shadersLibraries used: OpenAL, OpenGL, Boost, Crypto++, CxxTest, DevIL, SDL, SpiderMonkey, Vorbis, wxWidgets, XercesOperating Systems:Windows 2000, XP, XP64, Vista/7/8LinuxMac OS XSystem Requirements: 1 GHz CPU, modern graphics card (GeForce 3 at minimum), 512 MB RAMTools used: Visual Studio, g++, CppDoc, COLLADA, Debugging and Profiling tools includedGraphicsOpenGL-based rendering engine with shadersHierarchal skeletal animation and deformation system based on COLLADAFancy animated water with refraction, reflectionRealistic shadowsParticle effectsEnvironmental lighting effects (time of day, sunset)Flexible terrain renderer that uses alpha maps to seamlessly blend terrainMultiplayer networking: Peer to peer, no central server.Includes a level editor (Atlas) integrated with the Pyrogenesis engine.Extreme moddability: WFG started out as a game modification team, and true to our heritage and the FOSS philosophy, we believe being able to tinker with a game contributes to lasting fun and learning. Aspects of the game like game logic, artwork, and data can be tweaked with tools or by modifying XML and javascript files to totally change the game…. click here for more…
