Fantasy Flight Game's Masks of Nyarlathotep Expansion for Eldritch Horror is now out in general release!
And there's a flyer in the box about the forthcoming new edition of Masks for Call of Cthulhu, with a link to this landing page: https://www.chaosium.com/masks.
When Chaosium's new edition of Masks is released, it will feature a similar shout-out to the FFG board game.
This is all part of a closer collaboration between Chaosium and Fantasy Flight Games.
