Who Guards the Demon Castle?

Defend the demon castle

Who Guards the Demon Castle? is a single-player isometric defense strategy game for PC. You play a rookie demon lord trying to hold a growing castle against daily invasions, with a slime, goblin, and imp as your defenders. World domination can wait: the campaign follows the crew through 30 days of preparations and battles.

Plan each defense

Resources are limited, so you decide whether to build facilities, develop companions, or save for the next attack. Before a battle, check what intruders are trying to reach and the routes they’re predicted to take, then place monsters along the approaches. Afterward, review battle results and records to adjust your plan for the following day.
