About Galactic Missile Defense
Galactic Missile Defense is an endless, leaderboard-based shooter and tower defense game. You defend Earth from Martians who declare war after a space rover accidentally ruins their picnic, using three technologically advanced bases to hold the front line and attack enemy spaceships.
The Martian attack
In 2015, the Pry Rover lands on Mars and searches the planet’s desert for signs of life. The Martian inhabitants become infuriated by the robot’s presence, and you must protect Earth from the coming alien threat.
Defend the bases
You can upgrade your bases with machine guns or ultra-charged laser beams. Against tougher green-skinned enemies, you can activate more powerful weapons and booster packs. The game combines strategy and action, with fast-paced play that is easy to pick up but hard to master; higher levels have a hardcore difficulty.
Weapons and boosters
The game offers a range of weapons and boosters, including nuclear explosions, black holes, lasers and chain lightning guns.
