The manual of Questprobe featuring the Hulk credits John Romita Sr., Mark Grunewald and Kim McNair with creating the art; however, it is not clear if this is the in-game art, or the artwork in the manual. The manual feature quite detailed images. After this first title in the series, Scott Adams did a major upgrade to his adventure game engine. Because of this, Questprobe featuring The Hulk was much rougher than the subsequent titles in the series. It could only handle two word directions at a time and understood very few terms.
