Who will pass this course? Will it be the jock? What about the bookworm? And let us not forget about the professional rival! Only time and your sleuthing skills will uncover who the culprit is in Murder at Miskatonic. So get ready to uncover secrets and things that man was not meant to know as you ferret out the murderer. Fail and they go free, succeed and be the savior of the campus. The choice is yours!
Cthulhu Live's Mysteries of the Mythos: Murder at Miskatonic is a self-contained sleuthing game. It is based on the popular Cthulhu Live 3rd Edition live-action role-playing game but does not contain any complex rules or game mechanics and is instead based almost entirely on player interaction. It is very easy to run and will usually take about two hours to complete.
