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.
The Triarii were veterans of military service, usually in their 30s or 40s, with money to afford the best weapons and equipment. They made up the third line of heavy infantry, armed with stabbing spears. If the Hastati and Principi could not defeat the enemy, the Triari would come forward and finish them off. Usually they didn't have to fight.
