A short adventure game from 1990. You play Hugo in a quest to rescue your girlfriend from a house inhabited by monsters. Followed up by two sequels, ''Whodunnit?'' and ''Jungle of Doom'', and the basic premise was retooled as a ''VideoGame/{{Wolfenstein 3D}}'' clone called ''{{Nitemare 3D}}'' in 1994.

There's also a film called {{Film/Hugo}} that has nothing to do with the games.

!!This game provides examples of:
* AdventureGame
* AmateurSleuth: Penelope
* AngryGuardDog
* ArcNumber: [[spoiler:333]] is the solution to the combination lock in the first game and part of the phone number to dial in the second. Trying it on a safe later in the second game will just result in the game mocking you for thinking that would work ''again''.
** It also appears again in ''{{Nitemare 3D}}''.
* AscendedExtra: Penelope in the Second Game.
* BehindTheBlack: A puzzle to cross an impassible chasm is to walk along the pixel-sized ledge that is not described in the room description, and not visible on-screen.
* BoundAndGagged: Penelope in the first game, though this is more of an InformedAttribute since we only ever see her shadow.
* CuttingTheKnot: In ''Hugo 2'', you encounter the old man again and it looks like he's going to be asking you a bunch of stupid questions again. Instead, Penelope just knocks him out and continues on.
* [[spoiler:DecoyProtagonist: Hugo in the second game.]]
* TheDevTeamThinksOfEverything:
** Try throwing those matches across the bridge in the second game.
** Or kissing the FrenchMaid.
** Try typing "fuck" in the first.
* DistressedDamsel: Penelope in the first and third games
* FunetikAksent: The FrenchMaid in the second game
* HappilyMarried [[spoiler:Hugo and Penelope from the end of the first game, onward]].
* [[spoiler:HenpeckedHusband: Penelope certainly nags Hugo a lot.]]
* HeroesWantRedheads
* JungleJapes - The third game takes place there, where you must save Penelope from a poisonous demise.
* LetsPlay: PushingUpRoses and her companion PawDugan tackle this adventure with innuendoes all around!
** There's also a hilarious one by [[WebAnimation/ZeroPunctuation Yahtzee Croshaw]] and his partner [[spoiler:(not gay)]] Gabriel.
*** It's not with Gabriel; it's with a chimp that's been trained to imitate speech. But it certainly ''sounds'' like Gabriel, doesn't it?
* LockedDoor - A couple.
* MadScientist
* MisplacedWildlife: In the third game, the South American jungle has elephants, hyenas, and suspiciously African-looking natives.
** Amusingly enough, the game [[HandWave acknowledges]] the misplaced elephant, claiming it just escaped from a zoo.
* MonsterMash - Several monsters appear in the first game, most of which are having dinner.
* RedHerring - [[LampshadeHanging Lampshaded]] every time.
** In the second game, the final bits of evidence are red herrings based on {{Cliche}}s. You instead have to locate the character without the cliché motive.
* OffWithHisHead - If the butler from the first game approaches you while you're wearing the monster mask, he'll give you a pork chop. Let him catch you without it on, and you'll get ''this'' kind of chop instead.
* PaperKeyRetrievalTrick: In Hugo 2, the character you control encounter the locked door in a hallway but can't open it. It is opened in the finale, where Hugo puts the newspaper under the door and pushes the pencil through the keyhole to unlock the door, where you meet with a character in the hallway.
* SchmuckBait - When you pick up the whistle in the first game, the game asks, "I wonder what the whistle does?" But if you blow it right away and go into the next room, [[spoiler:you get killed by the dog]]. However, the whistle actually ''does'' have an important, positive use in the game.
* ShoutOut - The old man in the basement/cave asks you several questions relating to ''LordOfTheRings'', ''TheChroniclesOfNarnia'', and ''Franchise/TheHitchhikersGuideToTheGalaxy''. Thankfully if you never saw them, then [[ReadTheFreakingManual the help text will tell you the answers.]]
** The opening theme music is a mishmash of both the "''Franchise/{{Dragnet}}'' March" and the synthesizer lick from Boz Scaggs' "Lido Shuffle."
** The killer dog is accompanied by a brief clip of "(How Much Is) That Doggie in the Window?".
** In the sequel Hugo's girlfriend Penelope saves [[Series/DoctorWho The Doctor]] from a Dalek, confusing the hell out of a lot of stateside players who didn't get the BBC America channel (in fact, a few strategy guides treat it as a BigLippedAlligatorMoment).
* TrialAndErrorGameplay - Typically for its genre and era, experimenting with items has a very high probability of resulting in death.
* TwistEnding: [[spoiler:The murder in the second game? That was actually Hugo's uncle and cousin rehearsing a play where they play the victim and killer, respectively.]]
* TheUnseen: Penelope is only seen as a silhouette in the first game, but get's an actual sprite in the second game.
* UnwinnableByDesign - in the second game, woe betide you if you get those matches wet when they accidently drop into the water. The solution is to [[ViolationOfCommonSense drop the matches, pick them up, drop them again, pick them up again...]]
* WeWereRehearsingAPlay: In the second game, when describing a certain event.
* YouCantGetYeFlask - Parodied:
-->->open bolt
-->Please say "undo bolt".
