Slay The King is an action strategy game designed for Windows that immerses players in a battle against a corrupt monarch. In this game, players are tasked with building settlements of warriors to defend their lands and ultimately confront the king's forces. The game features fully destructible environments, allowing for dynamic gameplay where players can strategically place defenses like catapults, traps, and towers to protect their settlements. With a focus on resource gathering, players must collect wood and stone to enhance their defenses and prepare for the inevitable clash with the enemy.

The gameplay is characterized by classic real-time strategy (RTS) controls, enabling players to directly command their troops during battles. Equipping warriors with a variety of weapons such as axes, bows, spears, and shields adds an additional layer of strategy. Each level presents unique challenges that require players to hone their tactical skills and make critical decisions to emerge victorious in their quest to defeat the king.
