Nobody knows where these stone formations are coming from, or who sent them to Earth.
But you are the Defender, so its your job to use your spaceship to protect Earth by launching rock cubes into them.
Since these formations are made of anti-gravity rocks, your rock
projectiles will be magnetized by them.
If you complement them into rectangles, they will be annihilated forever.
Do this before they reach your shield and your ship!
