Deplete enemy's invasion forces and stop their offensive. When facing a large number of enemies, the only way to deter them is to use the powerful Haiphong battery.
Strategically deploy troops, vehicles, and aircraft to defeat the enemy and defend your base. Explore the battlefield to find enemy units hidden in the fog of war. Control of the Galaxy depends on your command!
Use towers to build a labyrinth from entrance to exit. Each tower can be upgraded 4 times. With each wave, enemies will become stronger, so use money you earned to upgrade reasonably.
One last turret stands between you and total annihilation. Destroy all malevolent alien ships by upgrading your cannon and building the ultimate killing device!
