The NES version of the game contains an Easter egg by entering the "CREDITS" door after starting the game. If the player holds right and presses A, A, A, B, A, Start, A, Select, A, Select, A, Start, A, B, A, and A, the name of programmer Erik T. Kiss will flash on-screen for two seconds. Afterwards, if the player heads to the Personnel floor and enters the apartment, they will start the game in Vancouver instead of San Francisco. This is a reference to the game's developers Distinctive Software, whose headquarters were located in Vancouver.
