A [[InteractiveFiction Text Adventure]], released by Creator/{{Infocom}} in 1983.

The story is set on Contra, a human-settled planet in the distant future. Civilization’s higher functions are tended to by three Filtering Computers, which control the weather, food production, and the transportation system correspondingly. These computers are monitored by the Central Mentality, a random guy who won a lottery and has been turned into a HumanPopsicle while his brain runs everything. The ideal is for the CM to stay in such a state for five hundred years, at which point they’ll be revived and replaced with the next one.

Of course, this is where things go wrong.

The current CM is suddenly woken by a series of error messages. An earthquake has damaged all three Filtering Computers, causing chaos and death on the surface. The guys that put him in there had no backup plans in case of such a catastrophic failure, leaving the CM to try and fix all three before too much damage occurs. Unfortunately, because he’s still in a tube, he has to mentally control six robots in the facility, each of whom has a very specific function. Even worse, a previous CM (Gregory Franklin) went insane and tried to destroy the planet, meaning the public has very little tolerance for this kind of situation. If the death toll gets too high, they’ll be coming down to fix the problem themselves...by shutting you down.
!!This Game Contains Examples Of:
* AndIMustScream: "A Cryogenic Nightmare" indeed. You can't see or move. You have six robots that between them ''almost'' make up one complete, functional human. And no way to communicate with the technicians coming to disconnect you.
* DifficultyLevels: The higher difficulty settings give you less time to complete all the tasks.
* DisturbingStatistic: The game keeps track of how many people die while you try to repair the systems.
* FailsafeFailure: The small informational booklet constantly mentions that nothing can possibly go wrong and, as such, leaves no real directions behind in case of a failure (and the ones they DO give are either BlatantLies or filled with half-truths). The problem is, you ARE the Failsafe, and when you wake up, you have no directions, your robots are in terrible shape, and the REAL damage has just barely begun. In particular, they never bothered to fix the incredibly helpful multitasking Fred robot [[spoiler:and neither can you]].
* {{Feelies}}: This is an Infocom game, after all. The Feelies included a booklet about the facility and the robots, a letter congratulating you on being chosen to serve as CM, a lottery card, and a map of the facility (with tokens to help you keep track of your robots). The box itself was a really cool looking mask of someone in cryogenic animations.
* FridgeLogic: Invoked in-universe, the manual implies that people who bring up objections to the system mentioned on the FridgeLogic page tend to get "lucky" in the next lottery.
* FromBadToWorse: Two more earthquakes hit at a set number of moves. The first causes an acid spill in one corridor; if a robot passes through it, they’ll die. The second quake causes enough damage to the Filtering Computers to shut down food production and distribution, sending the death toll skyrocketing unless you finish repairs immediately.
* AGodAmI: One of the previous [=CMs=], Gregory Franklin, went this route, and it's made the public a tad unsettled at your existence since then.
* GuideDangIt: You know that map we mentioned back in the {{Feelies}} entry? Well, the game neglects to tell you where the room exits are, which room is which, etc. You know, the things you need to know in order to get anywhere? The game also fails to tell you what each robot does and what commands they’ll respond to. Meaning, if you try to play without the Feelies... good luck.
* HarderThanHard: The highest difficulty level, "Impossible", is accurately named -- shortly after the game begins, the sun explodes and everybody dies.
* HumanPopsicle: The player character.
* LotteryOfDoom: Congratulations! You've won the lottery! And your prize is being locked up over twenty miles underground, frozen for five hundred years, while your brain is used to run your entire civilization!
* MeaningfulName: Each of the robots has a name that matches their function. There’s Iris (the vision robot), Waldo (the grabbing robot), Sensa (who senses photonic emissions and ionic discharges), Auda (who can hear things), Poet (who speaks in a kind of cipher at times), and Whiz (who connects you with the Central Library Core).
* MultipleEndings: Downplayed. [[spoiler:Depending on how well or poorly you did, you could be considered having "a home in the country and an unlimited bank account" or "[[BurnBabyBurn being burned in effigy]]".]]
* NightmareFace: The [[http://gallery.guetech.org/suspended_mask/outer-front.jpg original release's box cover]]. That face was 3D molded plastic, and probably sent young children screaming. The eyes are printed on the manual behind the mask, and it makes them follow you.
* NintendoHard: You have to manage six robots, each of whom see and work differently from the others, while an incredibly unforgiving time limit ticks away. This was rated "Expert" for a reason.
* NoEnding: The instant the last computer is fixed, the game exits. [[FauxSymbolism This represents the CM shutting back down for the rest of his/her stay.]]
* PressStartToGameOver: By selecting impossible difficulty.
* RedHerring: Fred, the seventh robot. He's a multipurpose model, which would make him the most useful machine in the room, right? Too bad that Franklin completely destroyed him. You can find his body all right, but you’re wasting your time if you try to repair him. [[spoiler: That wire inside him might be of use though.]]
* RocksFallEveryoneDies: The inevitable outcome of "Impossible" mode.
* ShoutOut: After you've helped the technicians [[spoiler:fix the pipe leak from the Filtering Computers in the Maintenance Area]], when they return to the Sleep Chamber, they mention playing a game of ''VideoGame/{{Starcross}}'', another Creator/{{Infocom}} game.
* SpeaksInShoutOuts: Poet can be a whiz at this sometimes, making references to Creator/WilliamShakespeare and the ''Literature/AlicesAdventuresInWonderland'' series, for example.
* TeamworkPuzzleGame: Because the robots are designed with one specific function, you have to make use of all their talents to finish the game.
* TimedMission: From the start of the game, you have to fix all the Filtering Computers before the people come down and kill you. You CAN shut down the transport system[[note]]or steal the repair crew's equipment, or lead them to some of the damage[[/note]] to give yourself a little more time, but if it comes to that, you’re pretty much dead.
* UnwinnableByDesign: If you lose the wrong combination of robots, the game is pretty much done for.
* UnwinnableJokeGame: [[HarderThanHard Impossible Mode]] is just that. The sun goes nova after only a few turns, destroying Contra.
* VideoGameCrueltyPotential: You're ''supposed'' to be preventing a planetary apocalypse. But if you prefer, you can just sit back, maybe murder your own robots for fun, and watch the world burn...
* VideoGameCrueltyPunishment: ... until they come down and turn you off.
