About Galactic Missile Defense
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!
It leans fully into strategy, so if that's your thing, it delivers. Whether you want a quick five-minute break or a longer session, it runs smoothly on just about any device.
A couple of things help once you get going: Reload during cover, never in the open. Memorize the spawn points of enemies on each level — patterns repeat.
Galactic Missile Defense is free to play and ready to go on Glaze Games — no app, no account, just tap Play and start.
