This is a community submitted press release.

Leave behind the days of "We walk into the room and roll Investigate." Eureka: Investigative Urban Fantasy is a TTRPG all about investigation, and its purpose-driven mechanics let players take initiative, use their characters' unique strengths to find clues, and deduce conclusions themselves - and it's all available on itch.io, payment optional!

As of January 30th, 2025, two new adventure modules have been released for Eureka: Investigative Urban Fantasy!

Somewhere, a mother stares wordlessly at her hospitalized son who doesn’t recognize her and wonders why this is happening to her family. Somewhere, a private detective smiles as his client offers a generous reward for someone–anyone–to blame for what was done to his children. Somewhere, a young girl tears down the advertisements that were covering up the missing poster of her friend. 

The year is 1999, and society is equal parts optimistic and apprehensive about the new millennium. Fears of the Y2K bug are circulating, Bill Clinton is still in office, and the popularity of video arcades is on the decline.

A rash of hospitalizations and disappearances has struck in Shreveport, Louisiana, with all of the victims so far being teenagers and children. Each case might at first seem unconnected, save for their close proximity in time to one another sending ripples throughout the community. Local news has been covering the story for days now, capitalizing on the fear and uncertainty of concerned parents, something that might seem like a distant problem to each investigator, until it strikes someone they know….

"FORIVA: The Angel Game" takes place in Shreveport, Louisiana, 1999, as a mysterious condition seems to have taken hold of a growing number of local children and teens, and the word on everyone’s lips is “angel.”

This is a mystery-horror adventure that you can expect to take 2-6 sessions to play through, and, in my opinion, the best piece of fiction I’ve ever written. Also, it was Actual Played by the awesome Tiny Table Podcast, here is their linktree and a link to the first episode.

Man has built a city of steel and black blood atop the endless abyss. It is a beating heart bound together with labyrinthian pipe veins. Hundreds of miles away from civilization, it stands in the midst of the Gulf of Mexico with naught but empty horizons around it. Within is a vast structure of winding halls, grinding machinery, and thousands upon thousands of small parts working to achieve a grand design. It is the Offshore Oil Rig Neptune, and it was once run by 200 workers. Now, in the midst of the COVID-19 pandemic, it has fallen to more or less a dozen. These last vestiges of life in the rig spread themselves thin and work their hands to the bone to keep the massive beast running. In the midst of this overwhelming isolation, two members of the already shorthanded crew are unaccounted for, Seth Barlowe and Lukas Ward. The installation manager, Noah, has convened a meeting to try to find out what happened to them. With the crew already severely shorthanded and tensions running high, a mysterious disappearance is the last thing anyone needs. 

“Mayday, Mayday, Mayday…” Hundreds of miles away from civilization, a distress call echoes out to a fishing boat about a hundred miles south of shore in the Gulf of Mexico. It hails from a city of steel and black blood atop the seemingly endless abyss, powered by a beating heart bound together with labyrinthian pipe veins - the Offshore Oil Rig Neptune. The distress signal continues, in a haggard and nervous male voice: “This is the fixed drilling platform Neptune (spoken three times). 

Mayday, Mayday, Mayday, fixed drilling platform Neptune. My position is 27.383 North, 93.299 West. My vessel is under assault by an unknown perpetrator, and I am requesting immediate evacuation.

I have fourteen persons aboard, this message will repeat.”

A few moments after the message is received, a radio response from the Coast Guard reports that they have received the Neptune’s distress call, but they are weathered-in due to a storm - neither boat nor helicopter will be able to respond for eight hours at minimum. Those aboard the fishing boat set a course to investigate, perhaps out of compassion or perhaps out of legal obligation - and what they will find when they arrive is anyone’s guess.

"The Eye of Neptune" takes place in 2020 during the height of the pandemic lockdowns, and actually has two possible starting points, one where your characters are fishermen picking up a distress signal from an off-shore oil rig in the Gulf of Mexico, and one where your characters are workers on that oil rig.

This horror-mystery adventure module should last you about 1-2 sessions.
