There is no actual "bunker" but the PDC is in the basement of the Green Square video store (play on Redbox). Once you have spoken to the conspiracy theorist and brought him the bag of shredded documents, he will give you a fake badge to show to the receptionist at the video store.
The 35th island (August 2013) will be Virus Hunter Island.
