Space tower defense

Rapid fire, splash damage, or a well-timed slowdown? Mix three tower types to defend your space base, and keep upgrading as the battle unfolds!

8 waves. Bosses in waves 4 and 8.

How to play

Select a numbered site and build a Pulse, Mortar or Frost tower. Each enemy wave starts automatically when the countdown ends.
Use Mortars against armor and Frost against fast enemies. Earn credits from defeated enemies and upgrade towers to level 3. The battle keeps running while you build!
Protect your base through all eight waves to win. Need a different setup? Sell a tower to recover 70% of its cost.
