@Mudsox couple of notes when you turn off the power in the basement..
Make sure elevator does not work without power (as idea script a code where it reads the text: ''Hmmm no power or this elevator has no power''
Make sure the washing street spinning things are turned off
Make sure the spinning thing on the police station roof is turned off
Make sure to turn off all lights at the gass station (i still see some lights that are on)
Make sure the spinning piramide is turned off at the arcade building
Make sure to turn off the 2 lights behind the arcade b
