Our take on Planet Modular TD

Rather than centering on one solved tower arrangement, the game makes changing combinations part of the structure. More than 60 modules, limited resources, varied enemies, and level-specific mechanics replace the fixed-build expectation common to simpler tower defense formats.

What is Planet Modular TD?

Planet Modular TD is an offline tower defense game about protecting a space base from waves of aliens, humanoids, and predators.

Players place and construct towers along enemy paths, then modify their performance with more than 60 modules. Modules can add effects such as poison, freezing, confusion, stunning, enemy redirection, weakening, income, or splash damage. Levels introduce different mechanics across planets, while enemies may weaken, disable, or bypass defenses. The game includes 40 levels, three skills, tower upgrades, crafting, exploration, achievements, and easter eggs. Resources are limited, and there is no single ultimate strategy, so tower and module combinations must change across levels.
