On May 13, 1976, chaos erupted as an alien invasion occurred. The aliens used a space hyper tunnel to travel to Earth from far away. Their mission: conquer and destroy. They had a weapon, a special sphere, which could destroy anything in its path. Humanity was unable to stop or avoid its devastating impact. Despite all efforts, the future seemed grim as the world prepared for the worst.
Faced with a threat to their existence, the US leaders decided to re-attack the aliens. The plan was to send astronauts through the hyper tunnel to destroy the alien's base. However, the aliens had set up barriers that conventional weapons couldn't destroy. So, NASA scientists designed a spaceship that could bounce back the alien's sphere weapon, effectively destroying the barriers. The astronauts were trained, the spaceship prepared, and the world waited as they set out on their dangerous mission.
