Earth Defense

Here, the story is initiated with a catastrophe spin—Jupiter has mysteriously vanished from the Solar System. Because the gas giant's enormous gravity is the barrier which protects Earth, now that it is gone, the world is open to an unprecedented surge of asteroid impacts. As NASA's leader, you play the role, and it is your responsibility to protect humanity and ensure survival in this apocalypse from space. To address the issue, you must access the master control panel by pressing W. The panel is your mission hub: pressing A activates side duties and missions that pay you money, and pressing D activates the deflector panel in which asteroid defense stations may be tracked and improved. Every mission that you complete pays you cash, which you will use to purchase advanced deflectors to defend Earth.

The deflector panel reveals three basic pre-installed asteroid defense systems, offering limited but crucial cover to players. Proper progress is achieved, however, through the built-in quiz of the game. The quiz tests your space and alien object information with correct responses being rewarded with more efficient and powerful deflector systems. The more clever and accurate you are, the stronger your planetary shields are, basically giving you more time against the unrelenting onslaught of asteroids. In charge of missions for profit, strategic purchasing, and intellect-based unlocks, you have to carefully navigate Earth through its most dangerous time in history.
