Universe Destruction

Introduction to Universe Destruction

One day, in this vast universe, a strong force appears to destroy the interstellar federation. The Federation are trying their best to protect their civilizations from extinction in the whole universe. YOU with your BEST FRIEND or alone will control your own spaceship which can travel millions of light-years with a blink of an eye. The spaceship is named after its creation name, Weed, the Destroyer. Weed, the Destroyer is an ultimately advanced spaceship. It can make a planet vaporize in a few shots, a big star collapse, and turn into a black hole in a few seconds of continuous shooting mode. YOU are, fortunately, not part of the federation alliance. YOU ARE THEIR BIGGEST ENEMY OF ALL TIME.
