Hugo III, Jungle of Doom! (named Hugo's Amazon Adventure in the Hugo Trilogy re-release) is a parser-based adventure game designed by independent software developer David P. Gray and published as shareware by Gray Design Associates in 1992. It follows Hugo's House of Horrors (1990) and Hugo II, Whodunit? (1991). The game uses the same text command format of the previous games, and it's the first game in the series to feature custom artwork in every scene.
