The Fourth Protocol is a video game in the adventure genre developed by Electronic Pencil Co. Ltd., The and published by Ariolasoft UK originally released in 1987. It is currently playable on DOS, Amstrad CPC, Commodore 64.

This interactive fiction computer game is based on the Cold War espionage novel by Frederick Forsyth, published in 1984 by Hutchinson Publishers. As the hero of the novel, John Preston, you have been appointed head of C1(A), an agency of the British Secret Intelligence Service. You uncover a plot, called AURORA, to seize power in the Soviet Union hatched by a secret faction of high-level minds. To stop their plan, you must read a lot of information found in top-secret folders, conduct wiretaps, monitor and interrogate suspects and informants, and gather data and clues.

The game has three main sections: The NATO Documents, The Bomb and The SAS Assault. A secret code must be obtained to move from one to the other. Icon-based graphics provide the means to carry out the investigation, although you can't click with the mouse (you have to examine the icons with the spacebar). Plot twists and developments occur during the game and are communicated to you with text descriptions.

It is possible that we have multiple downloads available when different versions exist.
