Tower Defense: Galaxy

Far from Earth, a blue portal stands at the edge of a remote planet under attack. In Tower Defense: Galaxy, alien ships push across winding routes through 40 missions, and the invasion ends only if that portal falls. Defensive lines rise across several locations, with fortifications bending the route into a maze that stretches enemy movement and cuts down wave after wave.

How to play?

Place structures along the road before the first assault reaches the map. Money from destroyed ships pays for turret upgrades, and stronger guns change how each defense works on the field. Slowing fire can hold attackers in range. Area blasts hit groups clustered inside the maze. New weapons unlock after several completed missions, adding more firepower for later battles. Survival Mode removes the mission limit and sends wave after wave at your defenses. A nuclear strike can hit one selected area when the line begins to break.
