Royal Defense - Invisible Threat PC

Battles rage on in the kingdom with Invisible Threat, a tower defense expansion delivering three fresh episodes for dedicated fans. Players tackle balanced levels in Wasteland's sharp cliffs, Fiery Plateau's burning terrain, and Mystic Valley's enchanted forest. New enemies demand fresh tactics, while four unique units-Skeleton, Necromancer, Fire Elemental, and Nature Elemental-bring diverse abilities to the strategy mix. This indie casual title challenges true tower defense players with four new achievements and unique quests tied to the episodes. It includes 150 free crystals for store upgrades, offering flexibility without requiring their use to finish. Casual strategists ready for intense trials will find plenty to conquer on PC.

The battles haven't stopped raging in the kingdom! Invisible Threat contains three new episodes for true tower defense fans. We've spent more time on balancing the levels for Steam players. We've also added new enemies to diversify the game. You'll need to use new tactics to beat them!
