Basic Information

Delta Green is a campaign setting for Call of Cthulhu (i.e. using the Cthulhu Mythos). It focuses on an American government conspiracy dedicated to fighting supernatural and extraterrestrial threats.

List of Tropes Used in Delta Green

• Body Horror (protomatter.)
• Cosmic Horror (already an intrinsic part of Call of Cthulhu)
• Eldritch Abomination (too many to count)
• Government Conspiracy (several around the world, including the "default" parent organization the player characters are members of)
• Mad Scientist (many of them work for Majestic-12)
• Masquerade (Majestic-12 doesn't want any competition in their field.)
• The Puppet Masters (the Mi-Go, again)
• Sealed Evil In A Can (Majestic-12 is far too fond of trying to open them)
• Squick (this has become a running gag on the Delta Green Mailing List)
• Sufficiently Advanced Aliens (the Mi-Go, among many others)
• Sufficiently Advanced Technology (Majestic-12 has a lot of this stuff lying around. Not that they would actually understand it…)
• The Government (one of the main differences between the original Call of Cthulhu is the frequent use of this trope. Not that it makes the situation any better…)
• Those Wacky Nazis (the Karotechia)
• Time Travel (the Philadelphia Experiment. It Got Worse)
