I am curious I have never played the nightclub version how do I play it?
Im guessing you mean how to start the Nightclub mode. Just pick Nightclup instead of admin.
But for the way its played, you basicly have to keep the characters from shutting down the generators in each areas by making sounds at the area thats being tamperd with. There is two characters that does that, but only one of them will tamper with the generators.
On the left side of your station, you have to block them from stealing the diamond.
The front of the station is your lights for the club, and they have to be the same color as the DJ using on the stage in the monitor.
There is a room to your right, but i have not found out what its for yet, other then it might be the room were the diamond is kept.
