Session two of this went very well. This was more action than investigation oriented, with our brave academics confronting several deep ones behind the murders.
This gave us plenty of opportunity to test the combat and fleeing rules. These flow pretty well, and both have a good sense of the back and forward of scuffles and chases. Although coming very close to it, none of the investigators were killed (although one was seriously wounded). On the other hand, they didn't actually kill any monsters either.
After getting out of the ritual chamber (which the creatures did not seem keen to leave), they decided to dynamite the place closed and return to Arkham and ponder the discovery that something called a Cthulhu will wake when the stars are right, and that this is in about six months.
I got to have a lot of fun with the one character who has 'in the blood' as their drive, too. Good times.
