Commander Keen 9: Battle of the Brains Overview
Commander Keen 9: Battle of the Brains presents a scenario where the protagonist must prevent the destruction of the universe. The antagonist, Mortimer McMire, intends to achieve this by destroying a giant star.
Keen operates from a space station equipped with multiple transporters, which allow travel to distant worlds. Access to the final teleporter, believed to lead directly to Mortimer, is secured behind controls that must be activated first. This requires Keen to successfully navigate four different worlds to enable his confrontation.
The narrative follows directly from the events of the previous installment, Dead in the Desert. Keen is now reunited with his friends aboard the Bean-with-Bacon Megarocket, having escaped the planet Calidune, when he learns of the impending threat.
