Our friends over on the Delta Green subreddit have been hard at work, specifically Agents jets_or_chasm and _morlock_ .
Using data gathered from the 1986 American census (to make sure names would be period accurate for agents in their 30’s today) and a little programming, they created a Python script called DGGen to create countless pregenerated Agents of every sort. There’s a PDF with 960 sample Agents along with themed packs of Agents for particular purposes: an FBI office, a CIA station, a gang, and more.
