SQUARE: Block the World

You think you can stop doomsday's arrival?

Well you're our last applicant so you'll do just fine.

SQUARE: Block the World is the beginning of Project Square being used for the greater good, and that means saving the entire world from an asteroid shower. Vaporize those in your path, make it to the depths of the galaxy, and maybe after all that we'll find a way to get you home. Eventually.

Game & Assets - Nerreave

The world's most brilliant and scientific minds have been collectively working together to create a perfect shuttle to protect the earth with. Today was the projected day for doomsday, where the asteroid belt would come to crash with Earth and destroy everything. SQUARE is the last hope of humanity, being a shuttle in which its bullets can vaporize any asteroid it shoots. Your goal is to go deep into the belt and block the world from disaster. After your excellent performance, and your ammo has been used up, it would be time to take the galactic highway back home.
