Wildfire Games (WFG) is a group of hobbyist game developers in the process of producing a freeware real-time strategy (RTS) game. The name of this project is 0 A.D. (zero ey-dee"). 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.

That game engine is called Pyrogenesis and it is specifically designed for flexibility and ease of modification. Game logic, artwork, and data can easily be changed through data files. The engine itself is modual in design to provide maximal flexibility while still remaining efficient. Pyrogenesis therefore provides a solid platform on which to work on individual features of RTS games, and can be used to create a completely different game from 0 A.D.'s design.

0 A.D. has been in development since 2001. The team members are largely students and game development hobbyists. The game has always been intended to be released as freeware and available to all. None of the participants have been or will be compensated financially for the contributions they have made. The reward for those that have contributed is as varied as: the ever elusive experience gained by working on a large scale group projects, to simply the pleasure of creating an RTS game they have always wanted to play.
