Ghostbusters: The Video Game is full of ghosts, but not every memorable encounter is really a boss fight. The true boss layer is the group of named set-piece fights that change the pace of a level, force you to use the tools differently, or feel like the chapter’s real supernatural centerpiece.
The biggest fights in Ghostbusters: The Video Game are the encounters that turn a chapter into a showdown. They change the pace, force a different tool rhythm, and usually leave the clearest memory of the level around them.

What counts as a boss fight here?
A boss fight here is any encounter that works like a chapter climax, a major gate, or a full set-piece showdown. That includes giant monsters, elite ghosts, and a few franchise icons that turn into full encounter events instead of ordinary enemy pressure.
1. Slimer
Slimer is the game’s first big tone-setter. He is not the hardest fight in the campaign, but he sets the tone because he teaches the section what kind of game this is going to be: fast movement, environmental chaos, and Ghostbusters history wrapped into a playable chase.
Use the early campaign material around him as your starting point:
2. Librarian Ghost
The Gray Lady works as one of the campaign’s cleanest “learn the encounter logic” bosses. The fight is not only about burning down one target. It is about controlling the shield pieces around her, staying calm when the room gets noisy, and then switching quickly when the opening appears.

3. Stay Puft Marshmallow Man
Stay Puft is the biggest spectacle fight in the front half of the game, and the one that most instantly sells the “playable third movie” pitch to people who grew up with Ghostbusters. He is part nostalgia flex, part crowd-control problem, and part giant target-management set piece.
The most useful walkthrough lane for him is Panic in Times Square.
4. Spiderwitch
Spiderwitch is one of the better examples of the game mixing pursuit, interruption, and survival pressure. She is dangerous partly because she will not politely stand still for you. If you let her feed and reset, the fight drags. If you keep pressure on her and manage the extra threats around the room, it feels much cleaner.
Use these pages together:
5. The Chairman
The Chairman is a great example of a fight that looks like a straight duel but is really an environmental priority test. The important lesson is not “shoot the boss harder.” It is “control the portals, then punish the opening.” Once you respect that rhythm, the fight makes much more sense.

6. Azetlor the Destroyer
Azetlor is the kind of fight that rewards knowing the full kit. It is not enough to stay alive. You need to understand what the fight is asking for and switch into the right answer at the right moment. That makes him one of the better late-game checks on whether the player has actually learned the toolset.
Use these together:
7. Imprisoned Juvenile Slor
The Juvenile Slor is one of the campaign’s most distinct creature fights because the whole thing turns around the Slime Blower lane. That makes the encounter useful beyond its spectacle value. It proves the equipment tree is not decorative. The game expects you to know what certain tools are for.

8. Shandor
Shandor is the full late-game payoff. He is more than a stronger ghost. He is the fight where the story, the cult material, the ghost-world pressure, and the upgraded weapon logic all finally collapse into the same moment. By then the game expects you to read phases, swap tools cleanly, and stay composed while the arena gets loud.
The most useful support pages here are:
A few named encounters that sit just below the top tier
A few fights live in the gray area between regular enemy and full boss. Pappy Sargassi, Chef DeForrest, and some of the heavier composite enemies are all memorable enough to matter, but they do not quite dominate their chapters the way the biggest set-piece encounters do. They still deserve coverage, just usually through the mission pages and entity pages rather than a whole top-level boss hierarchy of their own.
Why this boss layer matters
These fights are where the campaign shows what its combat system can really do. They test tool switching, target priority, movement, and the ability to stay calm when a room turns chaotic all at once.
