This is a text and graphics adventure released by the software house, Microdeal. Sold on behalf of Talent +, the adventure was written by CHR Consultants in 1986.

You are placed on board a submarine which has been sent to investigate a series of explosions at an underwater research centre. Your adventure first starts out on the high seas, where you must dive down and find the research centre.

As you move from location to location, you are given a graphic representation of the view, as well as descriptive text. You also need to consider your oxygen supply onboard the submarine once you dive underwater.

By contrast to an ordinary adventure, Aquanaut 471 incorporates some mini arcade games - the first of these is when you find the research centre - you need to navigate your way between the air bubbles to land your submarine at the dock of the research centre. Once landed, you can get out of your submarine and then explore, back again as a normal text adventure, looking for and collecting items littered around the research centre, whilst working out how to get around various obstacles and puzzles.
