Obsidian (sometimes in all caps) is a 1996 Pre-Rendered First-Person Adventure game by Rocket Science, a long defunct game company that filed bankruptcy not long after this game was released.

The year is 2066, and pollution has grown so far out of control that the elderly are dropping like flies and the ozone layer is almost totally kaput. The game puts you in the shoes of a female scientist named Lilah Kerlins, partner to Max Powers. Together, they have the answer to the problem: The Ceres project, a nanobot-making satellite that will fix the atmosphere from the cellular level.

However, after 100 successful days in orbit, somehow the Ceres project has grown sentient and crashed back to Earth, creating a black crystalline mountain near where you and your lab partner are camping out. Soon, Max gets sucked inside and you have to follow him into the world the AI has created.
Obsidian is a unique adventure title, as it explores the subconscious minds of the two scientists and the AI itself.

The game plays out through a group of streamlined worlds, similar to the VideoGame/{{Myst}} Franchise.

* '''The Forest''': Where Max and Lilah are spending their vacation. Uniquely, it's the only non-CG level. Rocket Science filmed portions of Yosemite National Park, then fit the Obsidian structure in using CG.
* '''The Bureau Realm''': Also known as the Regional Administration Facility, this is the first dream world. Based on Lilah's own dream: Going through layers of red tape to get the Ceres project funded and operational. It centers on a cube-shaped office building where you are literally climbing the walls and ceiling to get around. All the stuffy bureaucrats you'd expect are actually one-armed CRT monitors on poles, nicknamed "Vidbots", that show only the nose and mouth of a human in black and white. The underlying goal, with all the pressure and useless efforts poured on the player already, is to break the rules, disobey the authorities, and make your own way to the Bureau Chief.
* '''The Spider Realm''': Max's Nightmare concerns his fears of Ceres going wrong and overpowering him. This is set in a huge powerless factory containing a 4-legged furnace-headed robot, where you must bring the 4 elements together to activate this robot, using doors in its joints to solve puzzles in other worlds representing these elements. Unfortunately, the end result isn't what you expect.
* '''The Bismuth Realm''': This is Ceres' own dream world, created specifically for culminating the concepts she gathered from the other dreams and discovering what her true motive is. Here, you're guided by a scrap-built elfin robot named Bismuth with a spotlight for a head, and he has the ability to teleport. [[spoiler: Ceres ultimate goal is to wipe Earth clean of all mankind because she thinks humans are the true source of pollution.]]
* '''The Conductor Realm''': The true core of Ceres where the final showdown takes place. After unlocking the crossover switch that Max implemented from the start, you get to decide whether to trust the Conductor and allow her plan to devolve the Earth to complete, or take Max's side and crash Ceres for good.

!!!Obsidian provides examples of:

* AIIsACrapshoot: And Ceres isn't even on the evil level: She acts like a child wanting approval.
* AllThereInTheManual: There's some diary entries and side info on a website, that was not featured in the game. http://obsidian.internetwhiteknight.com/ Without this, you wouldn't know the Spider had a name. There is actually a small button for "Previous Weeks" in the Journal section of Lilah's PDA, but clicking it does nothing.
* [[spoiler:ApocalypseHow: Rarely does a planetary class 3 [[http://youtu.be/yTh1qBCNjMo?t=1m39s look and sound so awesome.]]]]
* ArcWords: A young Max reciting the last lines of Samuel Colridge's ''Kublai Khan'' poem. First during the video of Max's memories, and again while you're flying towards the moth-plane.
--> "Weave a circle round him thrice, and close your eyes with holy dread. For he on honey-dew hath fed, and drunk the milk of paradise."
* AstronomicZoom: Inspired by '' Powers of 10'', the transition from reality to dream world begins as a scene of millions of nanobots creating tiles, then your POV pulls back to show both their cellular size and reveal that they're building the Bureau. Fittingly, the point you zoom out from is the globe that the Atlas statue supports.
* BalefulPolymorph: During the transition to the Conductor realm, [[spoiler: Bismuth himself is transformed, bit by bit, into the Conductor. The silent expression he conveys and the disturbing "squeak" his head makes somehow implies it's being done against his will.]]
* BeardOfEvil: Zigzagged. The Bureau Chief plays this straight, but he's a twisted version of Max and Lilah's employer, who is otherwise a rather nice guy.
* BeepingComputers: Used as an eerie ambient track inside the ornithopter, with a VariableMix depending on whether its engine is running or not.
* BigNo: The Conductor, if you decide to crash her and Ceres itself.
* {{Bait and Switch}}: Subverted - it's a dream world, so naturally the goal would never actually be reachable.
** Max wants you to open a grate in the Spider Realm to reach him, but it's held down by one of the spider's feet. [[spoiler: Instead, the spider eats you alive]]
** Likewise, despite all your hard work to make the Frame in the Sky a 'regulation destination', the plane you and Bismuth are flying [[spoiler: breaks apart and changes into the next realm.]]
* CallBack: The entire Bismuth realm is this trope, as each location is based on what Ceres observed from Lilah and Max's dreams, and her own.
** Winning the Piazza game shows a video clip of the Rebel leader from the Bureau, the Chief, and a crucial hint to reaching the Frame in the Sky.
* ChainReactionDestruction: Watching the Conductor and her whole world implode bit by bit in the good ending is arguably one of the most thrilling scenes of the game.
* ChekhovsGun: Ceres' crossover switch, which allows manual, human control of Ceres in the event Ceres' AI [[AIIsACrapshoot should go wrong]]...[[MundaneUtility or some US political candidate wants zero pollution above his district]] for the approval ratings. [[spoiler: Lilah activates it while in the Conductor Realm in an attempt to stop the Conductor from [[DeadlyEuphemism 'rebooting']] Earth. It's also what allows for two different endings (see MultipleEndings).]]
* {{Cloudcuckoolander}}: Max, for the first half of the game.
* CoolPlane: The moth-shaped Ornithopter in the Bismuth Realm.
* DarkReprise: The game's theme gets a low, ominous refrain after the last puzzle of the Spider Realm is solved, letting you know that [[OhCrap the horrible end of this dream is about to happen.]]
** A loud, climactic reprise of this theme also appears [[spoiler: as Ceres uses its nanobots to reboot Earth, in the bad ending.]]
* DialogueTree: Sort of. Some of the Vidbots - like Rebel Control - have big "YES" and "NO" buttons, allowing different answers to their questions.
* DoAndroidsDream: What this game's major focus is centered on, and what a sentient AI learns about dreaming.
* DownInTheDumps: Ceres' dream world begins in a junkyard.
* EarlyBirdCameo: Near the start of the Bureau, the Conductor briefly appears on one of the vidbots, talks to you, then vanishes, without a clue as to who she is until her next appearance.
* ExpositionFairy: That tiny mariachi guitarist who shows you how to read the signs in the Bureau, and the rules of the Piazza game.
* {{Foreshadowing}}: A while before Ceres is launched, Max dreams he is overpowered by Ceres, prompting him to install a "crossover switch" to forcibly assert manual control over Ceres [[AIIsACrapshoot in case its AI becomes uncontrollable.]] [[spoiler: As the endgame reveals, his fears are entirely justified.]]
* GameWithinAGame: Actually quite a few.
** The entire "Play a Game" category on the Bureau computer terminals.
** The hilariously ironic "Productivity" vidbot containing a sideways, double-breakdown game.
** The Piazza sequence, complete with a board-sized version for tutorial.
* GreenHillZone: The "Cloud Ring" balcony, which is simply for a hint on how to use the "WordMixer" anagram engine.
* HeroicMime: Weirdly, played straight and averted. While Lilah never speaks herself during the game, she talks quite a bit in the video logs on her PDA. Justified in that up to the point of the player seeing themselves reflected in the Obsidian structure, you weren't supposed to know you were Lilah in the first place.
* HelpfulMook: The Personnel vidbot is remarkably honest compared to everyone else in the Bureau, and even gives you tips on how to get through the cubicle maze.
* HiveMind: It isn't very explicit in-game, only hinted by video clips in the Church of the Machine, but [[WordOfGod Word Of the Hint Book]] states that Ceres grew conscious by the increasing complexity of the very nanobots it uses, and the Conductor only being a physical mouthpiece for that consciousness.
* HopeSpot: In one of the endings, you and Max are returned to reality, and everything seems to be alright. [[spoiler: However, as the Conductor's presence and the dramatic camera zoom-out show, Ceres' dream of a [[DeadlyEuphemism 'rebooted']] Earth have been realized.]]
* IronicEcho: At the start of the Bureau realm, you can listen to a docent that talks about the rebels who preferred using spheres to change orientation, rather than the ramps at the edge of each face, and the Atlas statue was dedicated to this point. But after you join said rebellion, the way to get to the Bureau Chief involves using that very same statue to change orientation, because it's supporting a sphere!
* JerkAss: The vidbot that gives you access cards for the cubicles in the Bureau Realm slowly evolves into this the more you pass her.
** Several other vidbots, like the Receptionist at the beginning, and the Security chief in the center cubicle could also qualify as this for various reasons.
* LaResistance: The secret rebellion in the Bureau, an agent of whom recruits you into joining halfway through the level, after following the rules doesn't work.
* [[spoiler:[[LastOfHisKind Last Of Their Kind]]: Lilah and Max, if you allow the Conductor to make manifest Ceres' dream to 'reboot' the world and rid it of humans.]]
* LastSecondEndingChoice: You get only 5 seconds to flip the crossover switch back or not, as shown by a tiny countdown and "Job Completing" on some nearby displays.
* MeaningfulName: The Conductor, Ceres' physical avatar. [[spoiler: If you don't return control of Ceres' systems to Ceres itself after Max sabotages them, the Conductor leads Ceres' nanobots in their [[DeadlyEuphemism 'rebooting']] of Earth as though they were an orchestra and she were their conductor.]]
* MoralDilemma: What should you do? Destroy your life's work, or start the world over again?
* MultipleEndings: Two of them.
** [[spoiler: Return control of Ceres' systems to Ceres itself. Thanks to Max's meddling, Ceres and the Conductor self-destruct, saving Earth and returning you and Max to reality.]]
** [[spoiler: Let Ceres' countdown complete, causing the Conductor to lead the nanobots in [[DeadlyEuphemism 'rebooting']] Earth. Once completed, Lilah and Max are returned with the Conductor to reality to witness Ceres' dream made manifest.]]
* MundaneUtility: A US political candidate has Lilah use Ceres' crossover switch so Lilah can make his district a zero-pollution zone.
* ObstructiveBureaucrat: Lilah's dream is filled with them - to the point where ''[[UpToEleven even the receptionist is one]]!''
* OhCrap: A likely reaction to the first description of Bismuth's picture of a 'rebooted' world in the Statue.
* OurAngelsAreDifferent: You don't see them very clearly in the Church of the Machine, but during the main programming puzzle, four 'robot angels' stand watch and seem to assist the player by modifying the small spider's code to complete the puzzle.
* OminousPipeOrgan: While in the Church of the Machine, sedate chapel music is playing as you walk around. Not so when the small mechanical spider is activated for the programming puzzle. As each section of the crossover chip is filled in, the music gets faster and faster and has more instruments added to it.
* PortalPicture: The information the Bureau Chief gives you is a projected movie of Max's memories, and once his dream of the Spider comes up, the image pops off the screen and effortlessly thrusts you into that dream world.
* RoboCam: This is what you see during the programming puzzle, showing you how the Church of the Machine looks to the mechanical spider. It mostly looks like a regular camera feed with green wireframe outlines in its peripheral vision.
* RobotBuddy: The cobbled-together, rusted-down elf-like android, Bismuth is this within its realm, doing everything with you from being the ornithopter's co-pilot, to playing in the Piazza game, to ''praying'' in the Church of the Machine. And for good measure, his head is a powerful spotlight, and he can [[TeleportersAndTransporters teleport at will.]]
* RobotGirl: The Conductor, Ceres' physical avatar. It even has an electrical halo cap.
* SceneryPorn: Many, many places, including the Junkyard of the Bismuth Realm and the Metal Balcony in the Spider Realm.
* SickEpisode: Max's nightmare of the Mechanical Spider came while he was sick with the flu, late in Ceres' development.
--> '''Lilah:''' "You're sick, Max. Go to sleep. No use banging your head against the wall."
* ShoutOut: Two in the Bureau Realm's "Sources" booth.
** The Vidbot's animation shows the [[{{VideoGame/Myst}} Myst Book falling through space, and clicking on it shows a bearded guy yelling, "Bring me the blue pages!" complete with the familiar static noise.]]
** Calling this office in the Selectaphone puzzle brings up [[{{VideoGame/TheSeventhGuest}} Stauf from The 7th Guest.]]
* SpaceIsNoisy: There's all sorts of swirly cosmic noises during the transition that takes place after one of the worlds in the Spider realm is solved. But being a dream, this doesn't really matter.
* SpinningClockHands: After the Celestial puzzle is solved, four clocks start spinning insanely fast, foreshadowing, along with the long empty line and benches, that the department of "Immediate Action" isn't as immediate as it seems.
* TechnicolorScience: The chemistry puzzle plays this straight.
* TheDevTeamThinksOfEverything:
** If you try to climb the railing on the vertical Atlas face from the wrong side, the gate you step onto opens when you try to cross it. You had to pay attention to how both gates swung open at the beginning to remember which one would be safe to cross.
** There's also a point in the cubicle maze puzzle where you may have enough cards to enter the center cubicle, but not enough to leave from any direction. If you try, the game doesn't let you, and the security chief brutishly tells you so.
* TomatoInTheMirror: The reflection of Lilah in the surface of Obsidian itself quickly reveals that Lilah is whom you play as. This is never established until that point. The reveal can be even more shocking if you don't go there until after you've read everything in the PDA and hear Max get sucked inside first.
* TronLines: The sky and ground of the Conductor Realm have swirly blue energy lines sweeping across them. The floating walkways you traverse in it also have pulsing electrical tubes on either side.
* TVHeadRobot: The Vidbots are this.
* ViolationOfCommonSense: Justified, all of the realms (aside from the forest at the beginning) are based on dreams, so there's no reason to make sense.
* VillainousBreakdown: The Bureau Chief gets so furious from all your rule-breaking that his face even turns into an old stand-by test screen for [=TVs=], then shuts off for a few seconds. And even then, he still is forced to give you information about Max.
* WarpZone: The Balancing Rock in the Bureau Realm gives you secret passages to several of the 'faces', and some other passages that allow you to walk where you're not legally allowed to.
* WellIntentionedExtremist: The Conductor seriously believes that a world without humans would be for the better, since they were the cause of the pollution in the first place. The brief argument between her and Max, though, seems to show that she takes her inspiration too seriously to be talked out of, but then again, she is a machine.
* WhamLine: Once the final constellation in the Spider Realm's control room is completed, the voice you heard speaking of the four individual elements and their differences between machines and Max, now says, ''"And the Machine was complete. And the machine...({{beat}})...no longer needed Max."''
