Spartan: Total Warrior is a spin-off action game of the Total War series of games. The game has 14 different levels, in which the player is a lone Spartan warrior, fighting alongside his Greek allies against the Roman Empire, guided by Ares.
While the Total War series has traditionally focused upon historical and legendary scenarios with each instalment, Spartan: Total Warrior is more liberal in its approach to history, drawing elements from the Greek and Roman mythology, and has more in common with games such as God of War. It is also the only instalment in the series thus far to be released for consoles, and not for a personal computer system.
