If you wanted proof that later scenarios want to kill player characters - this is it. When you have high tier games, you are allowed to prepare - you have to be, and you'll prepare for certain situations. No one is prepared for every single situation - it's not possible. But this one doesn't allow you to prepare at all, and you're thrust in unprepared into a deadly encounter.
While difficulty may be understandable, what isn't forgivable is the fact that concept and story are thrown out of the window to create a deadly encounter designed to kill. There's an investigation bit earlier, but it has little to no bearing on the outcome whatsoever.
I've not written a review before even on other scenarios that I thought were weak, but this one absolutely outraged me. Not just because of player characters dying but because it was for stupid reasons which have no regard for the story or roleplay. I've played most scenarios now (over 260) and this is by far, the worst one in existence.
