So I have heard a few things about this scenario including that it is difficult and has balance issues.
My group played it for the 1st time yesterday and we kind of crushed it. We finished it with 1 out of 8 doom on the final agenda, we had 1 investigator with 3 horror remaining and 1 with 3 health remaining (the others were really healthy). Now we didn't get max xp or anything, but we did get 4 xp. We did not play perfectly, but we did do pretty good. We also had some bad luck early on drawing 4 tentacles for the 1st 10 tests.
I am curious as to what other people have experienced.
I did witness Minh pick up 7 clues as a single action, that helped us a lot.
