0 A.D.

About

0 A.D. casts you as the commander of an ancient civilization in a real time strategy battle for dominance. Build settlements, collect resources, and train armies to outmaneuver rivals in fast-paced combat scenarios. The single player and multiplayer modes let you test tactics against AI or human opponents while managing economic and military growth. Units and structures reflect historical design without strict period accuracy prioritized over fun. This free open source project runs on PC Linux and Mac systems. Despite ongoing development the core gameplay loops show strong polish with over 100 unique units and evolving community mods. Strategy forums highlight its depth for RTS fans while accessibility keeps new players from feeling overwhelmed. The volunteer team updates the game regularly adding civilizations and mechanics since its 2009 debut.
