Castles on Clouds

Castles on Clouds is a roguelike tower defense game set on a procedurally generated island. You build towers to protect your castle from endless goblin hordes, planning your layout to counter the threats to your kingdom. User-controlled procedural generation lets you shape each level, while unpredictable challenges make every playthrough different.

Towers and defenses

The game has five core tower types, each with multiple upgrade paths, distinct damage types and characteristics. Artillery towers deal area-of-effect damage, magic towers ignore enemy armor, and melee towers spawn units that fight enemies at close range.

Cards and relics

Leveling up earns unique cards, while defeating bosses rewards powerful relics. Cards grant bonuses to towers, spells and buildings, and their effects can combine into powerful synergies and distinct interactions. Relics enhance tower stats and abilities or grant new powers.

Progression

Completing challenges earns metaprogression rewards that enhance tower abilities and unlock upgrades. Challenges also provide access to new buildings and powerful spells.
