The fact that you can dispose of a meddlesome policeman or innocent witness by throwing them off the balcony is one of the best things ever to happen in this game.
Hype for hotel!
Murder at the Excelsior Hotel will be on the live stream November 26th!
Feel strange that we have a live about a scenario out a month before ... But this will be perfect occasion to ask some question about independant products, like the regularity in release of independant scenario out-of-event 
And still not spoiler on cardgamedb or qr-code page. Where is my spoiler dose ? I want it ...
So where Union & Disillusion is Pandemic, this is Betrayal at Hill House, except it doesn't have the traitor mechanic (or does it? No really, I don't know. It's possible some endings have it).
I played it with Preston, my first time playing him. First run, I got swamped by Doom quickly. Too many cops, too many clues. Rather than tear down, I played again right away. My ending resulted in a boss fight that Preston handled easily with the Fire Axe.
1 failure and 1 success, true solo, took me a little more than two hours, so not an especially long scenario, which is nice.
As far as rewards:
Sgt Guarddog is pretty great. Many will want to add this to a campaign just to get him, especially tanks.
