King's Knight is an NES shoot'em up action-adventure game set in the Kingdom of Izander. The quest follows four warriors working toward the rescue of Princess Claire from a dragon.

• Cleaned, tested, and guaranteed to play. Authentic cartridge.
• Fast-action shooting gameplay is spread across five stages with changing terrain and enemy patterns.
• The playable team includes a Knight, Wizard, Monster, and Thief, each tied to the game’s four-warrior structure.
• The story centers on Princess Claire and the Kingdom of Izander, giving the arcade-style action a fantasy quest framework.
• Stage progression builds toward a combined-warrior finale after the earlier character-focused areas.

King's Knight carries early Square Soft fantasy styling into an NES action format rather than a traditional turn-based RPG. Its mix of shooter movement, fantasy characters, and five-stage structure gives it a distinct place among Square’s 8-bit releases.
