Gladius is a turn-based gladiatorial RPG. Players try to build a championship gladiator school by gaining experience through fighting battles in the arenas and recruiting new members.

The story of Gladius starts just as two schools begin the pursuit of the Championship. It follows the epic saga of two young heroes: Ursula, daughter of the barbarian king from the land of Nordagh; and Valens, the son of Imperia's greatest gladiator. Become one of these characters and embark upon a spectacular and brutal journey to fulfill their destinies to keep the world from heading into another disastrous war.
