This scenario is shockingly racist and reads like a white-nationalist conspiracy theory.

This scenario's antagonists are the Tcho-Tchos, an embattled Asian ethnicity who are intrinsically evil from their very birth. So cartoonishly evil, in fact, that the leader of their political advocacy group, the CAAA, is also a member of a flesh-eating cult. No sensitivity readers are credited for this project, and it was written exclusively by white men. The writers of Delta Green seem to be fairly progressive people, and I doubt they intentionally wrote the scenario to be this hateful, nonetheless what they've made isn't "mature cosmic horror". Its the racist anxieties of an author from the 20s reimagined as a police procedural by contemporary game designers.

Some might suggest that you could homebrew the problematic elements out of the scenario, and indeed you might but at the end of the day, I still had to read through this racist drek. If I pay for a prewritten scenario I shouldn't have to "fix" it.
