Project Nemesis is a fan driven website for games that use the One-Roll Engine (like Nemesis, Wild Talents, Reign and Monsters) or Chaosium's Basic Roleplay System (BRP) (like Call of Cthulhu) and the Delta Green setting.
Pick an Agent PC; the one with the lowest SAN, or the one with the most
recent bout of temporary insanity, or the one who has done the most
morally questionable things, or just the one who deserves it most. As a
Night at the Opera is wrapping up, remind them of the existence of
their day job (FBI, CIA, whatever) and that they have received a memo
reminding them that their biennial Psychological Evaluation will take
place on the next Monday (or at some more distant future point if you
want it to hang over them).
Doubtless they will have questions - remind them that Psychological Evaluations, like performance evaluations and fitness evaluations, are a standard part of the job (especially if they carry a weapon in the course of duty).
The Evaluation consists of a written test, followed by an interview with a panel consisting of a high-ranking officer unconnected to the Agent, a Psychologist or Psychiatrist, and a representative from the Police Services Union/Association (or other relevant employee representative body) (These can be played by your other PCs for the session, or used as a way to introduce new characters).
The Evaluation
1) Written
There are lots of multiple choice and written tests available on the internet. Pick one that is used for diagnosing personality disorders, alcoholism, stress, or some other condition that the PC is vulnerable to. Remind the player to fill it out in character, and have them do it in front of you (and the other players). Take careful note of what the player SAYS while filling it out, any references to their DG experiences, things they wouldn't tell the panel, dialogue with other PCs as if they were there, etc.
2) The Panel Interview.
Panel members will open with some general questions about work, stress levels, family life, intended to relax the PC and get them used to the format. Once the PC has settled a bit, one of the panel members gives the others a significant glance. Leaning forward he says, "So, [character name]. What can you tell us about A Cell?"
Doubtless, the PC will deny, stonewall, or attempt to look blank.
At which point, the panel member will say (adjust the dialogue to suit your campaign, of course): "Well, that's odd. Because your co-workers tell us that you mutter about "A Cell" constantly. You say things like "I didn't want to kill him. A Cell told me to." or "When is A Cell going to call?" or "If A cell had sent me backup, that thing wouldn't have eaten [deceased cell member]'s brain". And then there's this" [holding up the written test] "What exactly is a `shoggoth' and why don't you want to tell us about it?".
Written around the edge of the test, in the spiralling pattern characteristic of schizophrenia and in the PC's handwriting, is anything that the player said during the written exercise that is incriminating or mythos-related.
Panel members will follow up on these revelations with questions about stress, dreams, hearing voices, talking to god, magical powers, occult conspiracies, and so on. It should gradually become obvious that the panel thinks that the PC has become schizophrenic, and has invented an elaborate conspiracy theory and a supernatural authority figure (A Cell) which justifies taking the law into his/her own hands.
However, the panel will also remind the PC that they are not there to "get" him/her but to help him/her realise he/she has a problem. If the PC will agree to therapy (including drug therapy), mandatory counselling, etc, he/she can have sick leave with full pay due to work related stress (records of fatal or traumatic incidents the PC has legitimately been involved in will be referred to) until a subsequent assessment determines that he/she is fit for active duty. If the PC has undertaken any unauthorised or criminal activities that they would like to tell the panel about, the psychological evaluation can also be cited in their defence in an inquiry or trial.
Attempting to phone A Cell at any time during this period results in the call connecting to A Cell Battery Recharging and Recycling Services, a small firm run by a thickly-accented Vietnamese immigrant in New Jersey.
What's going on?
This is up to the Keeper. Here are some options:
1) It's exactly what it seems to be. The PC has lost more SAN than is good for him and has started subvocalising about his situation, without realising it. His phone is being rerouted to prevent a security breach.
2) It's a setup by DG internal security, who are concerned that the PC's mental instability is a security risk. The testimony about subvocalisation and the altered written test may be real or fake, depending on the PC's SAN. The phone rerouting is part of the setup.
3) It's a stress test by Majestic's Project Outlook, designed to see if they can eliminate DG by convincing its members that it doesn't exist. The phone has been hacked as part of the stress test. The PC has been drugged to experience symptoms of schizophrenia.
4) DG really doesn't exist; the whole conspiracy is a folie a tres, a shared hallucination by the cell to cope with the Cthulhoid horrors they face with a pathetic pretence that there are people who know what they face and will back them up [the End of Campaign option].
5) Not only does DG not exist, but the Mythos doesn't exist either; the PCs are totally psychotic and have been on a killing rampage for the last X months, without any justification (break out the rules for "Power Kill", here) [the I Hate My Players option].
6) Due to influence by Hastur, the PC's reality is literally breaking down, starting with the bits that are most tainted, and rendered unstable, by Cthulhu Mythos knowledge. Delta Green is gradually transforming into the Secret Police of the King In Yellow's Imperial America. Police badges are seen with yellow signs set in them, etc [a good follow up to Night Floors].
Depending on which option you choose, this could be just a short interlude, or an opening (or closing) to a whole campaign. If the agent admits to (say) nightmares, or marital breakdown, but not to (say) machine gunning cultists, then they could escape with some counselling and a few weeks leave; they might even regain some SAN. If they crack and start babbling about horrors from beyond the rim of Yuggoth, or just open fire, the panel might take more drastic action.
Players may become upset if the reality of "their" character is warped by the Keeper in this manner. Keepers should not be autocratic, but should remind players afterwards that Call of Cthulhu is a game of psychological horror and insanity - and if they feel this bad about a change in how they perceive their character, imagine how their character feels when their universe is changed by the horrors of the Mythos. This scenario is meant to give them some insight into the existential dread that would beset any actual agent of Delta Green (if it exists).
