You are on the sea floor, 1500 feet below the surface. Around you there is only cold and dark — the sun's caressing rays bring nothing to this world. The pressure here is over six hundred pounds per square inch. This is a lethal place. There must be caution in every move you make, or the sea will claim your body and your soul. You and your companions are aboard the RSV Wallaby, a prototype research vessel of your own design. This is its maiden voyage; the attention of the world is upon you.
You are not alone.
And in the hours to come you will die. Unless you can master the fine art of Grace Under Pressure ...
One of the overlooked gems from Pagan Publishing, this is an compelling adventure set in a cramped underwater environment, and it uses that premise to great effect.
While this is an adventure that requires a lot of investment from both players and Keeper, the results are well worth it, getting the players fully immersed into the experiences
(I played this at a con some years ago, and it remains one of my favorite con experiences to date. Not only did the Keeper have the flat-maps of the submersible and the skiff, he also had 3-D models made of both sub AND characters, as well as a "Mobile Communications hub" to be used when the party split up and was unable to communicate face-to-face in character.)
One of the best one-shot adventures to CoC that I have read. Be warned, it should be run by two keepers working together. But I think a good keeper using cut-scenes could do quite a good job of it. But two keepers, seperate rooms and a few other things that they talk about in the text could make this a truly great experience.
But most of all, I would have loved to have seen this movie. Co-directed by Cameron and Del Torro.
Pretty interesting scenario, exploiting the primal fear of a situation where an isolated group of people is trying to survive against a threat way more powerful than they can even imagine. Keepers might have to do more than their usual studying, though. Preparation seems more challenging than the one in your usual stories.
