Dive into the deepest depths of the ocean with a flashlight, a sword and all the courage that you can muster. I hope you are not afraid of the dark because the environment is quite dire and gloomy down there.
Collect the treasures of the deep and bring it to the surface. Opulence awaits you... If you survive! You didn't think this would come easy and risk free, did you?
Get ready to face the creatures of the dark! There are many terrible beasts lurking down there, and they won't let you get away with the treasures. Thankfully you've brought your trusty sword and flashlight with you. Use them to your advantage and don't let your guard down for even a second.
Don't worry, you won't be completely alone. You'll get occasional support from the surface in the form of helpful advices or even new equipment... for a price of course.
Good luck trying to survive the seemingly endless onslaught of the creatures Deep Below.
