## What is Blue Dot Defense?

The aliens are coming for the pale blue dot. Hold the line.

Blue Dot Defense is a classic maze tower defense game you can play offline. 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.
