So have finally finished listening through this AP - took a while, what with my Ipod being stolen with me only halfway through, and having to listen on my laptop - and I think it's really solid. Once again, Tom does creepy survival horror REALLY well. The alien menace was unnerving to picture, and then scary as hell when the ship started SCREAMING.
In my opinion though, this one definitely suffered from being run as a con game. I think it added to the frantic, hectic pace this scenario ended up having - two hours to make the jump from creepy "just-around-the-corner-horror" to "Holy-Shit-All-Out-Gun-Battle" seems crazy to me. When Tom made the comment at the end of the AP that he thought it would have gone for four hours, it made a lot more sense.
The original poster mentioned that a map would have been useful in the game and just from listening, I agree. Most of the middle of the AP seems vague - I couldn't get a sense of where everyone was, which is much different from all of the Divine Fire APs - and a lot of the players kept making comments that they weren't sure where exactly on the ship they were.
This was definitely a fun listen - the scene where all of the PCs run back into each other on the main deck was hilarious.
"Ok, so they're all there."
"Who else is with them?"
"The captain."
"I douse him with gasoline."
Just beautiful.
