Just finished playing scenario 9 and it was a success on our first try! It went down like this....
Still playing with Mandy and Joe, from the very beginning, we luckily drew a molotov cocktail, brass knuckles and geneolgy research, flamethrower and mask of the messenger (exhibit instead of unique for Mandy). We then went shopping at the common item store a lot. This yielded us another .45. This gave us all the weapons we needed in the final fight.
We got the riots rumour very early so decided to let it run to stop anything worse coming out. We also made a decision to always put the blight token on the doom track to wake him up faster. We then ignored gates opening. ignored monsters and rifts/dunwich horror (to let the terror level go up and doom track increase), and spent our movement picking up clue tokens. We had the Hallejujah mythos card where Joe got blessed and he kept it until the end.
In the final fight our epic card was waves of madness, but we had one cthonian on the board. HoweverJoe had 14 clue tokens to use and Mandy's reroll. Cthlhu didn't even get a chance to attack!
OK so the score wasn't as good as it could have been, only being 8,, but we have always been in it to keep the same two characters from the first scenario to the last.
Bring on 10!
