While looking for entries to use in Tormsen's Unnatural Phenomena Jam, I found links to some of Gareth Ryder-Hanrahan's old Unknown Armies con scenarios from the early 2000s on the defunct game.eire site. The Wayback machine had captures of all the relevant .zip files.
John Tynes ain't dead but he's under a noncompete at Wizards, which is basically the same thing. Meanwhile Hanrahan is the best of the Pelgrane devs, his blogposts are better than most of the other guys' published products. But was he always a scenario writing powerhouse, even twenty years ago? I uploaded his UA con adventures here for people to read. I've never heard anyone talk about any of them so hopefully you enjoy reading along.
This is not a full review since I haven't run/played any of the modules. I'll likely never run them regardless of quality. If I ever get enough players together for Unknown Armies again I've got a bunch of my own stuff at the top of the pile to be run.
