Cutthroats is an interactive fiction computer game written by Michael Berlyn and Jerry Wolper and was published by Infocom in 1984. Like the majority of Infocom's games, it was released for most of the popular computer platforms of the time, such as the Apple II, PC, Atari ST and Commodore 64. It is Infocom's thirteenth game.
The game takes place in and around the fictional Hardscrabble Island. For centuries, Hardscrabble was a thriving seaport, but the local fishing industry died out in the 1920s. Most of the area's remaining population is an assortment of hard-luck types and people of questionable ethics.
The player's character is a skilled diver scraping to make ends meet. One night, an old shipmate named Hevlin barges in with a map indicating the locations of two previously undiscovered shipwrecks. Flashing between excitement and paranoia, Hevlin abruptly leaves, asking the player to safekeep the map. Naturally, the old sailor is murdered practically steps from the doorway. Someone obviously wants this map quite badly.
Note: The Amiga version came out in 1985 or 1986.
