Ninja Prophecy is a traditional RPG game, taking place in a fictionalized version of Japan.
The player controls a party of up to 5 characters during the main quest, which is centered around their efforts to stop Ozunu, a powerful being that has been resurrected in a failed attempt to gain his powers. Sub-quests are also available from a guild. Traveling between areas can be done with a simple click on the game's map. During exploring, enemies are encountered randomly and fought in turn-based combat using physical and magic attacks. Aside from the usual experience points and money, successful battles may also yield materials, which can be used for new items at a laboratory or blacksmith.
