Kingdom Under Fire: The Crusaders

Kingdom Under Fire: The Crusaders is a South Korean game from 2004 developed by studio Blueside in collaboration with Phantagram, which on Xbox offered an unusual and ambitious genre combination - the player simultaneously commands entire armies in real time as in a strategy game while also personally fighting in dense battlefield melees as a hero of hack-and-slash action. The campaign followed a sprawling fantasy conflict between the human kingdom of Hironden and the dark empire of Encablossa, offering two distinct storylines from the perspective of both warring sides, allowing players to experience the war from two entirely different points of view.

Battles in The Crusaders could depict hundreds of infantry, cavalry, and supernatural units on screen at once, while the player, as commander, could at any moment choose a specific hero and personally dive into the fray, blurring the line between tactical command and direct action in a manner unusual for its time. Units had their own type, formation, morale, and stamina, so even the best personal performance couldn't save a battle if infantry got flanked by cavalry or exhausted itself during a long march. Between missions, players could reinforce their army, train it, and upgrade its equipment, giving the whole campaign strategic depth and forcing players to think about army composition before even entering combat.

Critics praised the game precisely for this original hybrid concept and the epic scale of its battles, though they noted occasionally clunky controls and technical limitations on the first-generation Xbox hardware. Despite that, Kingdom Under Fire: The Crusaders stands as one of the most ambitious and expansive strategy-action games of the generation and cemented Korean development's reputation as a source of unconventional gaming concepts. The scale of the battles and the level of detail with which the game could depict massive armies in motion were, for the hardware of the time, quite literally pushing the console's technical limits.
