Galactic Missile Defense is a strategy tower defense (TD) game that takes place in space and puts you in control of three advanced anti-missile bunkers that are the last line of defense for Earth.
Any anti-missile base can be upgraded with a variety of weapons and boosters, but you must be careful because each decision requires skill and strategy. Once you reach the higher levels, the action will pick up significantly, so be ready to make quick decisions!
Have fun and good luck!
