I did a "speed run" of the module to get a hang of the procedures and oracle system and even so, my character (RIP) ended up with 11 stress and a ton of damage before the final killing blow. There is so much stuff to work with in the hazards section and memos from Quinn, I'm sure subsequent dives into the depths with future characters will have even more surprises! I logged my play-through with sticky notes in the zine, which I'm keeping in there for future characters to find.
