Types of Threats in Delta Green Scenarios

I looked at every official Delta Green scenario and tried to identify the main threat that the scenario is centered on and what "type" of threat it is. Why? I don't know. It could be useful for a random scenario generator, like Agent Obtuse's. Or maybe this sort of classification could be integrated in my scenario database and help with finding specific types of scenarios.

In any case, I identified the following types of threats in the scenarios I looked at:

• Great Old One (GOO): Great Old Ones are name-dropped in almost all scenarios, but this category is only meant for those scenarios that feature a GOO more or less directly.
  
• Mythos Faction: groups of Mythos creatures, like the Great Race of Yith, the Mi-go, etc.
  
• Human Faction: a large organization or cult, like the Karotechia, New Life Fertility, Majestic-12, etc.
  
• Creature: a single unnatural creature or maybe a group too small for the Mythos Faction label.
  
• Sorcerer: a human with access to hypergeometry or otherwise touched or transformed by the unnatural. Includes small cults.
  
• Weird Science: experiments gone wrong, sci-fi technology, etc.
  
• Haunted Place: your typical haunted house would fall in this category.
  
• Artifact: any item with unnatural properties, stuff you would find in ARCHINT.

Obviously a scenario can have more than one threat, either from the same or different categories. Feel free to leave a comment if you can think of any other categories that I missed.

I did not include campaigns in my categorization attempt (unless you count Iconoclasts). Also, I have not read all scenarios in detail and some of them I read a long time ago, so I might have forgotten some things. Anyway, here are the categories for all officially published scenarios, in alphabetical order:
