"Swordquest was an unfinished series of video games produced by Atari as part of a contest. Each of the games came with a comic book that explained the plot, as well as containing part of the puzzle that had to be solved to win the contest.
The Swordquest series had its genesis as a possible sequel to Atari's groundbreaking 1979 title Adventure, but it quickly developed a mythology and system of play that was unique.
The games of the Swordquest series (along with Atari 2600 Raiders of the Lost Ark) was one of the earliest attempts to combine the narrative and logic elements of the adventure game genre with the 'twitch' action gameplay of the action genre, making them some of the very first 'action-adventure' games.
