Masks of Nyarlathotep

The most massive episode of Dark Adventure yet conceived! Based on the lavish new edition of the beloved Chaosium role-playing campaign, this is a gigantic production over seven hours in length and with more props than usual.

In Masks of Nyarlathotep, the death of a dear old friend and an investigation into a doomed archeological expedition spiral into a global investigation with dire repercussions. Can a handful of intrepid investigators make a stand against an insidious and bloodthirsty cult? Can a diabolical conspiracy be thwarted before a doomsday plan comes to fruition? Is there any hope for mankind against the machinations of an Elder God or will they meet only despair, death and madness?

The "standard edition" of the show comes on a set of six CDs, with twenty bonus prop documents. We also offer an expanded Deluxe Edition that includes 82 prop documents. And for the truly mad, we are offering a Super Deluxe Limited Edition that features all that plus artifacts. For role playing gamers, we offer a special Gamer Prop Set that includes all the props you need to actually play Chaosium's game. (Some props needed for the show are not needed for the game, and some needed for the game are not needed for the show.)

Get It!
