In Untold Legends: Dark Kingdom players choose to play as one of three classes, each with its own style and weapons: the Warrior, who mainly uses strong melee attacks with a large hammer; the Mage, who uses a combination of ranged magical attacks and close range strikes with his staff; and the Scout, who is the agile alternative of a warrior, landing multiple strikes in quick succession with her daggers. Once selected, a character's class may not be changed.
When levelling up, the character is given predetermined additions to all attributes, and 2 extra points that can be added freely to any of these attributes. A skill point is also rewarded, which can be put into useful techniques that are dependent on each class, relative to the level requirements to learn these skills.
Game play consists of completing complex combos and using them to the players advantage (such as completing a combo to launch a fireball into a stone pillar, which proceeds to land on the enemies). Players can also collect weapons, armour sets and other items to aid them.
The game can be played by 1-2 players on the same screen. Online play for up to four players is provided via the PlayStation Network.
After serving the King loyally for years in foreign conflicts, an elite unit of knights return home to find it a changed place. They are appalled to discover that dark magic has corrupted their kingdom and that the King now plans to use the knights against his own people. The knights devise a plan to assassinate the malevolent ruler, but when the attempt on the King's life is foiled the would-be assassins barely escape and are on the run from an army they once served.
Many critics[who?] have praised the game's hack and slash system which is easy to pick up for most gamers and the ability to play as three characters. Criticism of the game came from its repetitive gameplay and lack of other elements.
