0 A.D. 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, from Iberia to Mauryan India, each depicted at their peak of economic growth and military prowess. Developed using Pyrogenesis, a ground-breaking new game engine custom-built to suit this project, 0 A.D. will give players a rich and entertaining real-time gaming experience.
Previews of the three new skirmish maps (maps where everything is placed by the designer but where you can change the settings: what faction the players are, starting resources, etc) added in Alpha 19. From the left they are: Alpine Mountains, Northern Island and Tuscan Acropolis.
