You were traveling with your comrades through the depths of the sea to explore its secrets when you heard shouting. There was a big crash and submarine darkened in a matter of seconds. You heard the captain shouting something about cowardice and shortly afterwards the sounds of fighting. You can only assume the worst, rebellion!
Will you find your final rest at the bottom of the sea or will you escape and see the daylight once more? Explore the submarine and use your wit to escape.
