Check your messages when you get back from the Stay Puft Marshmallow level. The new person's father or friend says "You're doing adequate work out there Luke, keep it up!". This reveals that his name is Luke Hoss.

When you are in the firehouse, go down by the containment unit. Look on one of the work desks to see a circular ghost trap that was used in the late 1990's cartoon called The Extreme Ghostbusters.

In the Ghostbusters headquarters, one of the monitors on the upstairs desks has the ending screen from the original Ghostbusters game on the NES. The monitor comes complete with all the spelling and punctuation errors.

When listening to the answering machine messages, one will be of a man talking in a gruff voice asking, "Who busts the Ghostbusters?"
