Space Invasion Tower Defense

Build and upgrade a dozen kinds of space towers to stop 60 waves of alien ships. Pick Fall-Down or 2-Way mode and a difficulty, and spend gold and gems wisely.

How to play

Mouse: click a tower in the right panel, then click the map to place it; click a placed tower to upgrade or sell. Space cancels placing; Next Wave calls the wave early.

Click the game first so it gets the keyboard. P or Esc pauses; the speaker button in the corner mutes the sound.
