DT Challenge - 7/8 Javascript - Space Invaders

Enlist now to command an alien space fleet to save your home planet from global catastrophe. Build a fleet of drone ships using advanced top-secret technologies, like algorithms, sequence, iteration and branching. On your journey to Earth, meet the Doctor, slingshot around a black hole, land on distant moons and mine for valuable resources. Your mission is to outsmart Earth’s Global Defense System in your quest for precious water.

We are counting on you, Commander! Long live the Zargan Empire.
