About Castle Guardian

Castle Guardian is a tower defense game set in a fantastical medieval world. You protect your castle from armies of skeleton soldiers and monsters, fighting alongside your companion, the Centaur. Strengthen your character and the Centaur as you repel enemy forces.

Defend the castle

Use traps, weapons and special abilities to hold off the attacking armies. The abilities let you teleport, attack from the air, stop enemies and deliver powerful spear strikes. Defend the castle across different maps, where each map has its own Market section.

Enemy armies grow stronger as wave levels increase, with up to 10 wave levels in a level. You also face powerful bosses that require strategy to defeat.

Markets and chests

Spend money at a map’s Market to buy items, level up the Centaur, repair your castle, set traps and empower yourself. You can also open chests from the Menu section using Magical Mushrooms to earn Gold and Costumes. Find mushrooms on the map based on your luck, or buy them from the Menu for 50 Gold.
