Poly TD is a strategy game with random generation elements, where the core mechanic is the merging of units on a circular arena. Unit evolution, achieved through fusion, allows for the creation of powerful beings that transcend time and space. The battlefield may feature the most unexpected historical and fictional figures, from humble peasants to legendary figures such as Siegfried, Joan of Arc, or Guan Yu. Even characters from Lovecraft's works can join your squad, opening the door to bold tactical experiments and unique combinations.
