This isnt an easter egg but I thought it was funny. As I play the game over and over I try different things to see what happens and if you let Stay Puff get to the top of the building he will not only kill you but knock you off the building.
I only mention it because I remember Dan saying in an interview that Ghostbusters dont die and that was an important part of the game to him. As far as I can tell this is the only place in the game that you are actually killed not just incapacity but killed. Knocked off the top of a 30 story building!
That does sound like a interesting thing to try out. I'll check that out.
