"The Incomplete Works of Infocom, Inc." Catalog:

CUTTHROATS places you on an out-of-the-way island populated by some of the most disreputable characters this side of Alcatraz. You're a diver for hire, and as decent, competent and stalwart as they come. The plot is hatched when a motley band of local salts gets wind of a shipwreck laden with sunken treasure somewhere in the waters surrounding the island. They offer you a piece of the action in exchange for your diving skills and your knowledge of the area's shipwrecks and their locations. (This information you have gleaned from a book of shipwrecks, which is included in your CUTTHROATS package along with your Outfitters International price list and tide table, and the amazing High Seas issue of TRUE TALES OF ADVENTURE magazine.) Now you must survive the perils of the deep - and the even greater danger that your crew may harbor a cutthroat - if you are to recover the treasure and save your neck. STANDARD LEVEL

Package Blurb:

In Cutthroats, you are a skilled diver living on Hardscrabble Island, a small seaport past its prime. You will try to salvage a sunken treasure from one of four shipwrecks; if you are successful, you will be fabulously wealthy and enormously respected among old salts. Some characters in the story will help you; others will try to stop you any way they can. If you can think logically and keep your throat intact, the treasure can be yours.
