"During the winter of 1927-28 officials of the Federal government made a strange and secret investigation of certain conditions in the ancient Massachusetts seaport of Innsmouth. The public first learned of it in February, when a vast series of raids and arrests occurred, followed by the deliberate burning and dynamiting - under suitable precautions - of an enormous number of crumbling, worm-eaten, and supposedly empty houses along the abandoned waterfront. Uninquiring souls let this occurrence pass as one of the major clashes in a spasmodic war on liquor." "The Shadow Over Innsmouth", H.P. Lovecraft
Suggestions for playing a DG operative that's in one of the other organizations given in the DG book. Playing a Majestic-12, Karotechia, or Fate operative that's also part of DG seems like a good way of making the paranoia palpable.
Delta Green could be brought back onto the fold if it could provide solid evidence to the Office of Homeland Security that terrorism was at least partially sponsored by occult groups and religious cults.
Every Cell and every Friendly not engaged in active operations is given the task of seeding information making it appear groups like Karotechia, et. al, work together. One aspect of this would suit a political game best.
Here is a rundown of an alternative DG campaign background. It replaces the Mi-go with Ophibians. The whole set up comes after a recently completed Cthulhu 1920s campaign which took three years to to run. To cut an obviously long story short, a human (player-character) of mixed serpent-people and human blood fulfilled an old prophecy to bring the Serpent People of the Dreamlands back to Earth, there to regain their dominion. So the next bit makes sense, I'll tell you that his (human) name is Christopher Larkin.
In the first pages of the shadow over Innsmouth its explained how, after the raid, the civil rights movement started a short-lived campaign against the gravely unconstitutional actions of the federal government (illegal arrests of American citizens, imprisonments without judgement, etc).
