It's been a long-standing tradition among certain of the more august members of the Esoteric Order to do up a big horror gaming extravaganza around Halloween every year. Since time immemorial, this event has been referred to as the "Call-of-Cthulhu-a-thon"...even if no actual CoC is run that day.
Last year, we did one big six-hour scenario. This year we decided to go for the "rock festival" approach and offer several smaller scenarios over the course of a day and let folks filter in and out as the mood struck them.
The second scenario, run by David L. and originally written for Call of Cthulhu, was run using the Achtung Cthulhu rules and features a fun little romp in which all the PCs are Nazis... Enjoy!
