Galactic Missile Defense is a strategy tower defense ( TD ) game set in galaxy, where you are in charge of 3 anti-missile defense bases that are the last hope to defend Earth.
Rush in defense action and defend against the alien invaders using strategic weapons like classic defense Missile, Laser, Plasma Missile, Black Hole, Nuclear Missile (Armageddon) and Heat-Seeking Missile!
You can upgrade any defense-missile base with a variety of weapons and boosters but you must be careful as each choice requires strategy and skill. The Martian space invaders have their own missile weapons as well, you must be prepared for quick decisions as the action increases dramatically once you reach the higher levels and the invasion from the Martian space Kingdom reaches it's peak. Make sure to destroy their missile attacks or Earth's last line of defense will fall.
