Star Tower

Star Tower is a three-dimensional tower-defense game about stopping another universe from pushing stars into yours. Starting with a single star-killing spaceship, you build a defense network to repel the incoming stars. You balance research and upgrades against buying more defenders, while the universe’s growing mass threatens to make it implode.

Advance through the rift

The game begins in two dimensions. You can move forward into the dimensional rift to reveal more of the path and take on greater challenges and rewards, or retreat when the fight gets too difficult. The path is near-infinite, with increasingly difficult obstacles and bosses.

Towers and powers

Research unlocks seven additional tower types, each with its own abilities and game-wide upgrades. Defeating boss enemies can unlock special one-use powers that temporarily change the laws of physics.
