Wow. BIG box.
HPLHS have outdone themselves on this production (and I say that owning prop set for Masks of Nyarlathotep *and* the Classic Prop Set).
Period maps, yes, and theater-realistic clues, yes, but there's a Weird Science radio that *works* (as far as the players know) and ... a genuine Mythos Tome marked as restricted and sealed against chance perusal by inquisitive eyes!
There are also three replacement seals because players will be players and will obviously break the seal to read Thatte Whyche Shoulde Notte Bee Seene Bye Human Eye. Fools.
There are audio clues needed to make the radio work (via an included bluetooth speaker), witness statements (best played NOT through the radio) and digital versions of all the "flat" clues (impossible to download the tome or radio).
Tip: The QR code with the link for all is at the front of the scenario booklet. The code on page 61 only downloads the audio clues.
My only reservation is that there is no PDF version of the scenario book itself. I like to read up while commuting using a tablet, and like to mark up the digital copy with post-it notes.. Even Chaosium offers a PDF copy with their hardcopy purchases now, so this is a puzzler.
I hope that the clues to be found in the buff envelope will be available for purchase as replacements as I can see the more delicate clues (eg newsprint) getting destroyed by greasy fingers over time.
