Galactic Missile Defense is a strategy tower defense ( 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.

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. Be prepared for quick decisions as the action increases dramatically once you reach the higher levels!
