0 A.D. is a FOSS game of ancient warfare, belonging to a genre of games called Real-Time Strategy (RTS). It is mostly implemented in C++, along with scripts in JavaScript, and runs on Windows, Linux and Mac OS. The game was last presented at Haifux in December 2009 and has developed tremendously since then, with advances in graphics, A* pathfinding, opponent AI and more. Aviv will demonstrate some of the new features of the game of particular interest to Comp Sci people and explain how he manages the PR and social media aspect of a volunteer FOSS project. Probable bonus: Pictures and experiences from Wikimania 2011, where Aviv is set to assist the organizers with media and PR aspects.
