I'm assuming that this will EVENTUALLY be available for general sale, like most of their other Gencon "exclusive" stuff.

"Event registration closes at the listed event time. Participants will be free to form their own groups to play through the scenario, there will be support staff on hand to help put people into groups. The special Gen Con scenario deck "The Eternal Slumber" will be provided to each participant. Something strange is happening in Cairo, Egypt. Seemingly random victims all throughout the city have fallen into comas, leaving doctors baffled. When Jessie Burke comes to you desperate for help, you find yourself obligated to assist, even though you may never again wake from a night of sleep. In this special event scenario for Arkham Horror: The Card Game, 1–4 investigators must search throughout Cairo and the ruins of ancient Egypt in order to find a way to lift this curse… and in the process, unveil a sinister machination between two forces far beyond our comprehension."

I will add the comment for those who are not aware...

FFG has a history of releasing the Lord of the Rings LCG Gencon standalones as Print on Demand retail packs. My local store has most of them. There is a very high likelihood that we'll see this as a retail product down the line, just like the much anticipated Labyrinth of Lunacy. Unlike LoL, this one is a 1-4 player standalone, so it should slot into a campaign just like Curse of the Rougarou and Carnevale of Horrors.

I'm sure they'll have it available at Arkham Nights 2018 in November as well (luckily for those of us that go each year).

whoops sorry. wrong thread

According to the Asmodee presentation at GAMA, it'll also be available in the Invocation Event this year as well.
