Doc Vs. Aliens is a shoot em'up game, set in the near future, where he tells the story of Dr. Ferdinand Stein, who was arrested in the asylum for believing that his predictions (that the aliens would attack) would be wrong.
However, scientist was right and a few days later they invaded Earth. with the attack happening, one of the aliens ended up stopping in the asylum and, unintentionally, released Stein. Desperate, he fled the scene and went to his secret hiding place where it contains some special vehicles (Ship, Car and Moto) that he made for that type of situation that the whole globe was suffering.
The aliens live on a planet called Planet Loo, which lies in another star system (but still in the Milky Way), yet they managed to reach Earth with a portal they had created. The purpose of the attack is because humanity is polluting space and, as a consequence, damaging other planets.
So for Ferdinand needs to leave the home planet, travel into space to reach the
portal and finally go to Planet Loo to try to make a peace agreement between them.
Will they accept the Doctor's proposal?
