Each page of the Walkthrough section describes one stage of the game's Career mode. Within each page, each section represents a checkpoint you reach within the stage. If you should go down, the game will reload the last checkpoint you reached. You can also do this manually from the Pause Menu. Any checkpoint you've reached in your career can be replayed from the Replay Mission option in the Main Menu. This feature is handy for trying to scan ghosts or Cursed Artifacts you may have missed on your first trip.
Throughout this guide, the following sidebars are used to bring your attention to certain aspects of the game.
This sidebar is used to show you any Ghostbusters that will be accompanying you for a particular segment. This is important since they will assist you and can come to your rescue if you're incapacitated. Proceed with extra caution if the sidebar reads None since that means you're alone; the mission will fail if you go down.
Scattered throughout each stage are an assortment of Cursed Artifacts for you to find. If your PKE meter shows a blue reading, a Cursed Artifact is nearby. You can use your Paragoggles to hunt it down and scan it. Scanning a Cursed Artifact secures it and earns you bonus money. Finding them also works towards an Achievement/Trophy.
