Kill Buck with the fire extinguisher on training day. You can find it in the apartment's kitchen on the ground floor. After your shift, return to your apartment and sleep. Continue sleeping until day four. Go to the facility to encounter the gangsters. You will eventually get to the location where you earn "Playing House". Instead of allowing the android beat you up, reprogram it with the Android Reconfiguration Device. Then, escape the lower levels. Once you are in front of the facility, continue to left until you reach the train station. Get on the train and end the game.
