Hero Online was created in collaboration with authors known for their work in Asian Martial Arts Fiction. The story-specific quests deepens the single player -likeness while maintaining the MMORPG elements.
Choose from four characters: The Ruthless Blade, Overseer of the Sky, The Piercing Eye, or the Elegant Mystic, each with their own strenghts, weaknesses and stats. Every character can choose from four classes (Warrior, Hunter, Physician, and Assassin) and advance to upgraded classes with more and better skills. The game also features mountable and non-mountable pets, which can be either tamed or bought. Mountable pets can't fight but can carry the master while the master is fighting and the non-mountable pets can fight and defend the master controlled by an AI system configurable by the player.
