Secret of the Sea

Publisher's blurb: The PC:s are on a diving mission and get a call to help with a rescue. This is a generic adventure, created for ANY type of science-fiction/Cyberpunk setting - OR for contemporary and even fantasy themed games! Most RPG rules based on any type of world with deep seas, should be possible to be used. Change what you need, fill in values according to your rule system used, add some more horror and action stuff as well as fleshing out NPCs - and you're done!
