You wake up in a dim submarine by yourself, and already deep below the ocean. There are a few buttons and switches in front of the windows for moving the submarine around. There are controls for taking black and white images.

There is a small sticky note on how to move the submarine around, but nothing else; it works on exact coordinates. You cannot see outside of the windows, but there is a radar that detects where objects are. There is also an oxygen meter..

Your time is limited.
