Arcade fun with space invaders! Use the missiles against alien invaders to win! Galactic Missile Defense is a strategy tower defence ( TD ) game set in space, where you are in charge of 3 secret anti-missile technologically-advanced bases that are the last hope to save Earth. Rush in defence action and clash with the alien invaders using strategic weapons like classic Missile, Laser, Plasma Missile, Black Hole, Nuclear Missile (Armageddon) and Heat-Seeking Missile! You can upgrade any anti-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. So what do you say Missile Commander, are you ready to answer the call of duty and defend Earth along with the whole Galaxy, or will Earth bow down to the power of Mars? Galactic Missile Defense is the latest free arcade / strategy / Tower Defense game from the makers of Angry Chicken : Egg Madness!
