About This Content

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!

Key Features


• Three new episodes
Wasteland – orcs have hidden amongst sharp and dangerous cliffs.
Fiery Plateau – destroy all the enemies on a burning plateau.
Mystic Valley – defend yourself against mystical creatures in an enchanted forest.


• Four new units, each with its own unique abilities.
Skeleton, Necromancer, Fire Elemental, Nature Elemental.


• Four new achievements. Unique quests made specially for the new episodes. Challenge yourself with exciting trials!


• The DLC also contains 150 free crystals for store upgrades. You can spend them however you like, since you don't need them to complete the game.

Please leave your comments and suggestions for improving the game and the genre!
