Detailed walkthrough
After receiving the personality holotape for the Sink Central Intelligence Unit from the doctors in the Think Tank, proceed to The Sink, activate the Central Circular Structure in The Sink and then install the Central Intelligence Unit's personality holotape. After this, the player must locate the modules for the other utilities in The Sink, which at the time of arrival have all been turned off. The first holotape, for the Sink, is located in the Magnetohydraulics Complex, inside the small building, on a desk against the back wall with a ruined terminal. Next comes the Auto-Doc, which can be found in the Y-17 medical facility on a desk on the upper level of the facility. The next module, the personality module for the Biological research station, is located along a fallen girder in the center of the X-22 botanical garden. Then comes the module for the Jukebox, named Blind Diode Jefferson, found on a desk in the the left second floor room of House #108 of Higgs Village. Following this comes the module Book Chute, which is found on the desk in the second floor office of Higgs Village House #101. Light Switch 01's module can be found in the X-2 transmitter antenna array, leaning against a coffee maker on the ground floor. It's counterpart's module, Light Switch 02, can be found on a storeroom shelf just inside the Big MT north tunnel. After this is Muggy's module, which is located in the back of a truck in front of the entrance of the Securitron de-construction plant. Finally comes the Toaster's evil module, located in a shrine to the right from the entrance inside the The Cuckoo's Nest. Then return to The Sink to activate the utilities, which can, if wanted, be shut down from the Sink Central Intelligence Unit.
