Hidden Door can make *anything* happen. Like a global food festival focused on pizza and also maybe subterfuge. But if "drama! at the international pizza contest" doesn't whet your appetite, why not remix things?

Or maybe you just forgot the location of the super-secret bank vault you're supposed to break into. The Narrator is the most important member of your heist crew. Give the narrator a call next time you play Hidden Door (and make "next time" RIGHT NOW by visiting hiddendoor.co)!

Uninterested in your rival's romantic advances? Have the narrator rewrite the script so you can pursue a different paramour. Want the treasure hunt to be more complex? The Narrator can add obstacles.

The Narrator is here to help! Want your story to speed up? Want to make it WAY MORE DRAMATIC? Want to spend more time in a specific location? Ask the Narrator! When you chat with your friendly DM, they can alter the pace of the game, your relationships, and what challenges you face.

OOP. We got postcarded. The Hidden Lair is now occupied by a seismosaur AND three allosaurs, courtesy of St. Remedius Medical College and @kyloboomhauer.bsky.social. Thank you for entrusting us with these ancient beasts 🫡
A postcard with the image "Seismosaur with Three Allosaurs," © 1986 by Doug Henderson in cooperation with David Gillette. Description from opposite side: The 40-foot long Allosaurs were among the largest Jurassic predators, but they were dwarfed by the largest plant-eater, the 120-foot long Seismosaur, discovered in 1986. Allosaurs may have hunted in packs, but would they have attacked a Seismosaur?A postcard featuring Seismosaur with Three Allosaurs by Doug Henderson in cooperation with David Gillette.
