Questprobe is a trilogy of graphical adventure computer games featuring Marvel Comics characters. The three games are Questprobe featuring The Hulk, Questprobe featuring Spider-Man and Questprobe featuring The Human Torch and The Thing.
The games were designed by Scott Adams, developed by Adventure International and the first was originally released in 1984 for the Atari 800, Apple II and Commodore 64 with the sequels being published each following year. The original plan was for a series of twelve games, but Adventure International's bankruptcy in 1985 brought a rapid and premature end to the line.
