MrM! Here are the answers for ya
Issue 1
* Page 8-9: Was that giant mask from the African ghost in "Deadcon I"? (If not from where?)
Yes * Page 9: Are those eyes in the wall based on "The Thing from Mrs. Faversham's Attic"?
No * Page 19: When Peter crashes through the wall, Winston was looking at mirror. What was that mirror based on?
The mirror is based on the one from the first magic trick in "The Cabinet of Calamari." Issue 2
* Page 5: When the Ghostbusters come down the stairs, there's that square shaped device atop the cabinet on the left, what is it?
That is just a device I made up Issue 3
* Page 9: There's this yellow device obscured by the "Clang Clang" sfx on the shelf in the bottom right panel, what is it?
Those are Spectral Gloves from the RGB robbritton, thank you for your question as well. The new pack in issue 3 is not based on the Zootfly design, however I can see the similarity. I remember seeing a trailer for the game, but it was just driving in the Ecto 1. When designing the pack, I referenced a lot of airline engines. We wanted something big and bulky that packed some punch.
