Commander Keen 7: The Keys Of Krodacia

Commander Keen 7: The Keys Of Krodacia is a direct narrative sequel, picking up the plot immediately after the events of the previous installment. The protagonist's objective is to locate and collect seven specific keys, which are required to unlock the sole entrance to a large structure on the planet Krodacia.

The story impetus comes from a discovered recording left by Mortimer, which Billy Blaze finds after returning to Earth and convincing his sister to let him search her brother's room. This message reveals that the antagonist is constructing a device called the Universal Toaster Cannon on the distant planet. The player's mission is to infiltrate this fortified base and prevent the weapon's completion.

This episode serves as a bridge, with its conclusion leading directly into a subsequent fan-made modification titled Dead in the Desert.
