Castle Defense Online

Castle Defense Online puts you in charge of a small group of soldiers protecting a city from frightening monsters. Its origami-inspired 3D style gives the battlefield a distinctive look while the changing enemy types keep your formation decisions important.

The core challenge is to block each attack by moving soldiers into useful formations. Since monsters have different weaknesses, success depends on observing what arrives and directing your limited forces toward the most effective response.

Slide on the game area to draw formations and lead the soldiers.

Watch the monsters approach, then change your soldiers position to block their path.

Adjust the formation continuously because different monsters require different responses.

Keep directing the group until the attacking monsters are defeated and the city is protected.
