King Cola's Court is where Oswald Oppenheimer, stage name Oswald the Outrageous, worked alongside his girlfriend Rachel Watkins before the Great War. A group of their friends also worked there, putting on magic shows for children as the main attraction.
The entrances to King Cola's Court are the theater main entrance and behind the King Cola's Castle Tower. There are restrooms to the right of the concession counters, and the theater room is located behind the counters.
Backstage there are two dressing rooms. There are stairs that lead to the second floor of the stage area and an elevator that takes the player character to the top of King Cola's Court. The sound room is also located on the second floor, down the hallway to the other side of the theater, past the storage room.
The top of King Cola's court is where the player character will confront Oswald and make the decision on how to handle the situation concerning him. In this area, the player character will find Oswald's terminal that requires his password, a cooking stove, a chemistry station and numerous radiation barrels. After confronting Oswald, there is a door that leads outside to the signal flagpole. The player character can unchain the other door by exploring the outside area.
