Alien Invasion - The Mission

The professor worked on a secret project his entire life, of which nobody knew anything, except his little son, Albert, who lives with him. He had a grand plan: to end the lonely, secluded life of humanity in the universe once and for all, and open the gate to new worlds, new galaxies, new technologies. The Star Gate, his great invention, was supposed to open a wormhole to worlds where peaceful, benevolent aliens live, who have the technology to cure all known diseases that humanity has long been fighting against. But something went wrong! Evil aliens have learned about the Star Gate and are on their way to Earth. They only have one thing in mind: to conquer the planet and enslave or kill everything that lives on it. The Star Gate MUST be closed immediately! Are you capable of accomplishing this? Can you save the future of humanity?
