Unlockables and Supplemental Data should be the archive side of Ghostbusters: The Video Game, not a loose pile of extras. In practice, this is the material that helps the section feel documented: collectible markers, side data, guide references, and the kind of mission-by-mission details that matter when you are cleaning up the whole campaign instead of only clearing the story once.
The Prima guide folds a lot of this information into the walkthrough layer itself, especially through map markers and side notes. So the most useful version of this page is not a vague celebration of unlockables. It is a clean path into the live pages that already carry the real useful data.
How the guide handles the collectible side of the game
The guide’s mission maps call out three especially useful kinds of extra material: Cursed Artifacts, Water Fountains, and Easter Egg / Achievement / Trophy spots. That means the collectible layer is tied directly to the mission pages rather than living off by itself in a vacuum.
That is the right way to think about this part of the game. You do not really separate the campaign from the archive work. You move through a mission, keep an eye on the side markers, and come away with more of the case file filled in.
Mission pages with collectible and side-data value

Reference pages that support cleanup and completion
If you are trying to use the section like a working guide instead of a one-page overview, these are the pages that help the most.
- Ghostbusters: The Video Game story and campaign overview
- Levels and missions in Ghostbusters: The Video Game
- Tools of the Trade in Ghostbusters: The Video Game
- Ghost Wrangling in Ghostbusters: The Video Game
- Tobin’s Spirit Guide in Ghostbusters: The Video Game
How to use this page
Use this page as the archive-side hub for the game. If you are cleaning up a run, start with the mission pages for collectible markers, then jump to the reference pages when you need wider help on gear, ghosts, or overall campaign structure.
That keeps the page honest and useful. Ghostbusters side material works best when it feels filed, cross-referenced, and ready to help the player find something real.
