Build a long, winding maze of towers and hold the line for 50 waves. A Mothership arrives every 10 waves. The aliens are coming for the pale blue dot. Hold the line. Blue Dot Defense is a classic maze tower defense. Enemies march from the top of the board toward Earth — place towers to build a long, winding maze, and make every step they take count. • 7 towers: Pulse Cannon, Gatling, Plasma Mortar, Homing Missile, Gravity Well, EMP and Tesla Coil • 7 enemy types, including warpers that fly over your maze, shielded drones and splitting swarms • 50 waves with a Mothership every 10 waves • Normal, Hard and Endless modes, plus fastest-clear records • Upgrade towers up to Lv.5, sell and rebuild freely • Play offline — no timers, no energy Ads are optional: watch a short ad only when you want a revive or a bonus shield. A one-time "Remove Ads" purchase gives those rewards without ads. Images courtesy of NASA/JPL-Caltech.
