->''You have the same choice we did.\\

You can die here, or you can do what you have to, to go on.''

''The Swapper'' is a puzzle platformer created by indie developer Facepalm Studios, in which the player is an unnamed astronaut who must explore the wreckage of the space station Theseus by manipulating a cloning device called The Swapper, that not only can create clones of yourself, but can "swap" your consciousness into the clones you created.

...Or can it? The device is not easily understood, and unravelling the mysteries behind it and why the crew of the space station died are both one and the same goal, and not everything is as it seems.

The player uses the Swapper to solve puzzles and restore a derelict space station so that you can escape, and many puzzles require you to send clones of yourself to their death while you swap your own consciousness into a new body while the old one gets crushed from falling from too great a height.

The models and environments are also created with clay and everyday items, giving it a {{Claymation}} look while still moving at 60 FPS.

!!Examples:
* AlphaBitch: Dennett, who refuses to believe the Swapper can switch and transfer souls and [[spoiler:who forcibly keeps trying to take control of The Scavenger]].
* ApocalypticLog: The Emergency Evac logs you can find in memory terminals.
* AscendToAHigherPlaneOfExistence: [[spoiler: The doctors and the original scavenger, all in one body, use the Swapper one final time to force themselves into the Head Watcher to see if they can "force" him to stop killing them. All it does is make them part of the Watcher HiveMind, and therefore, they become Watchers themselves. Whether they are content with this, or if its a FateWorseThanDeath, is unclear, but the dialogue of all the watchers on the space station changes when this happens, to reflect the new minds inside them.]]
* ArcWords: ''You can die here, or you can do what you have to to go on.''
* BlueAndOrangeMorality: The Watchers. As far as humans can tell, they are space rocks with no organs or moving parts of any kind. But they are alive, and immortal to the point that they have no grasp on the concept of death or CessationOfExistence, [[spoiler: to the point they don't realize they killed the crew.]]
* BodySurf: The Swapper lets you swap places with the clones you create. [[spoiler: Or invade beings you have not.]]
* BrainInAJar: [[spoiler:Dennett and Chalmers used the Swapper to force themselves into preserved brains in order to survive, trapped for over a century.]]
* CloningBlues: Heavily discussed to a disturbing effect.
* CompleteImmortality: The Watchers are hypothesized to have lived much, much longer than humans.
* CosmicHorrorStory: You're stranded on a space station that seems to be completely deserted and full of strange alien rocks; it's your mission to find out why.
* DeadpanSnarker: Dennett, especially against Chalmers as the two fight over ethics, souls, and science.
* DeathIsASlapOnTheWrist: The clones you make will die, whether it's by falling a great height, getting crushed by doors, or passing through a beam a white light that erases all clones in the room.
* DespairEventHorizon: [[spoiler: In the end the rescue team decides to abandon the main character because she is TouchedByVorlons and swiftly dying, leaving her with two brutal options, to commit suicide or steal the body of a rescue worker and leave her old body to die.]]
* DownerEnding: [[spoiler:Both of them. The player character either commits suicide or steals a rescuer's body. The consequences of the latter are unexplored, but based on the other rescuers' dialogue, they're likely to be severe. Regardless of which option you choose, the only Theseus survivors are left in an ambiguous level of survival that may or may not be positive from their perspective.]]
* DrivenToSuicide: [[spoiler:In the ending where you choose to stay marooned on the planet, your only option is to jump to a massive bottomless pit to your death, listening to the Watchers' comments as they try to understand what death is and why you are attempting it.]]
** [[spoiler: One of the minds in the Scavenger's body appears to attempt this with a giant set of gears, but presumably one of the others stops her (the lights go out, but we see the screen static that indicates a personality shift.) Most likely it was the Scavenger herself attempting suicide after being driven nuts by the other two voices in her head; and in the end she's the one who pulls the trigger on the swapper to put them into the Head Watcher out of desperation.]]
* ExpendableClone: Some puzzles even force you to kill clones to advance. There's no avoiding it.
* FriendlyEnemy: The Watchers dialog is sweet and friendly. Their nature is [[spoiler: so separate from the physical world that they spend their time struggling to understand basic physics such as physical matter and space. They have no idea they killed the population of the ship because they ''don't know what death is.'']]
* GravityScrew: About halfway through the game, gravity-altering panels are introduced, and the puzzles get even more mind-bending. There are also sections that take place in zero-G.
* HiveMind: The Watchers, which they refer to as a "great chain".
* HowUnscientific: Dennett can't stand the thought of the idea of a "soul" or that the Swapper "swaps souls about."
* {{Metroidvania}}: The game allows the player to explore the space station fully and collect orbs to power up consoles to unlock new areas, all in a 2D space environment with large doors and elevator lifts.
* MissionControlIsOffItsMeds: The voice over your radio gives you contradictory instructions, and generally acts unstable. [[spoiler:It's because she's actually three people in one body]].
* OnceMoreWithClarity: Near the beginning, you hear [[NewhartPhonecall one side of a conversation]] over your radio: "What you're telling me isn't possible. '''' Tell me [[PlayerCharacter who]] I just ejected into space." Much later, you find the security records, and get the complete message.
* OurSoulsAreDifferent: Heavily discussed and debated between Dr. Chalmers and Dr. Dennett.
** [[spoiler: And later, The Watchers discuss this too.]]
* RedOniBlueOni: The nature of The Swapper and The Watcher has put Dennett and Chalmers at each other's throats about the nature of each, and [[OurSoulsAreDifferent the idea of the human consciousness]] for some time. Dennett is TheSpock, scoffing at the idea of a Soul, while Chalmers is more idealist, believing "a soul is not just a brain." [[spoiler: And they've been at it for over a century.]]
* SamusIsAGirl: [[spoiler:The player is the first clone of the female scavenger.]]
* SentientCosmicForce: The Watchers are ''rocks'' with no moving parts or organs of any kind, but can communicate with each other and are very much immortal.
* ShoutOut: To real life philosophers Daniel Dennett and David Chalmers.
** Also several to {{Metroid}}: the map, door, space setting, and character design are all nearly identical. Moreover, there are two characters who are living brains and [[spoiler: [[SamusIsAGirl the protagonist is female under her helmet.]]]]
* SilentProtagonist: Why the protagonist doesn't speak is a mystery, but it is suggested that [[spoiler:since swapping causes memory loss, the protagonist (who is a clone) may not have anything useful to say because of her wiped mind.]]
* SlidingScaleOfIdealismVersusCynicism: When discussing the ideas of human consciousness, Dennett is cynical and Chalmers is an idealist.
* SpaceIsNoisy: Averted in free space segments, other than a justifiable "thud" from firing the Swapper or bumping into objects.
* TalkingToThemself: [[spoiler: Dennett, Chalmers and the Scavenger all end up in the same body, bickering among themselves.]]
* TouchedByVorlons: [[spoiler: Hearing the Watchers in one's head was the indication to the crew they were dying.]]
* TomatoInTheMirror: [[spoiler: You are playing as the first clone of a lone female scavenger using the Swapper for the first time, and are therefore proof that [[YouBastard the Swapper clones you have been killing have their own consciousness.]] The game starts when you are first created and tossed out in an EscapePod.]]
* {{Tsundere}}: The female scavenger seems to be this, jumping back and forth between helpful, condescending, and aggressive. [[spoiler: It's because she has the minds of three different people inside her.]]
* VoiceWithAnInternetConnection: Two female scientists, Dennett and Chalmers, as well as an unnamed female astronaut.
* YouCannotGraspTheTrueForm: The humans and Watchers mutually cannot understand each other.
* YourDaysAreNumbered: According to the console logs, the entire staff of Theseus start hearing the thoughts of The Watchers and realize too late that [[spoiler:listening to a Watcher will soon result in death. More unfortunately, the protagonist was listening to them the entire time, sealing the protagonist's fate.]]
