Capital City is the fourth level in Keen 1. It contains the second Vorticon Guard in the game. Despite the name, it is not very big or complex, but it is a long and horizontally oriented level. It requires Keen to get a yellow and a red keycard in order to get to the end. It also features a strange pedestal at its entrance, and is the only level to feature yellow blocks along with the blue and red ones.
There are relatively few hazards in the level. There is only one Garg and one Vorticon, as well as several Pat Pats guarding the red key. As is generally the case in Keen 1, the Vorticon can be easily surpassed; it is possible to trick the Vorticon into running off of the right edge of the level.
It seems that there is no way to get the upper and left-most lollipop on the level's entrance. (There is, but jumping left at the right moment is statistically very uncertain.)
This level contains one of the missing parts from Keen's ship, the Joystick.
