Trivia
The original idea behind the Questprobe series was to have twelve games, each with a corresponding comic book created by Marvel Comics. The first three games and their comics, featuring the Hulk, Spider-Man and the Fantastic Four's Human Torch and Thing, were released but Adventure International went bankrupt before they fourth game, featuring the X-Men, was completed. Marvel had completed the comic book and, years later, released it as part of their Marvel Fanfare series.
In order for the graphics to work under a normal DOS window, you have to type "MODE CO40" at the command line before running the game.
