A point-and-click adventure game developed by Pendulo Studios.

In New York City, homeless people seem to be vanishing left and right, only to be found immolated. Yet a strange "Y" shaped scar appears on seemingly unrelated people. The police are not giving much attention, so it is up to millionaire Henry White and his friend Cooper to begin to investigate these events. But that's only the start.

Years later, a man named John Yesterday wakes up from a failed suicide attempt with [[AmnesiacHero no memory]] and a Y-Shaped scar on his hand. What exactly did Henry White hire him for, and what is happening to the homeless people? Find out in this adventure game released for PC and phones.

'''Note:''' due to the game's story-heavy nature, even the names of the tropes themselves should be considered spoilers. As such, '''all spoilers are unmarked.''' Proceed with caution!
!!''Yesterday'' provides examples of:

* AlchemyIsMagic: Well, it does grant you Immortality.
* AmnesiacHero: John, complete with a DarkAndTroubledPast, amazing fighting skills and a beautiful sidekick.
* AmnesiacsAreInnocent: John Yesterday is fairly sweet-natured and romantic if somewhat morose due to his amnesia... but this trope comes fully into effect when you consider his past lives as the demented Choke and the murderous Satanic cultist Miguel. Possibly a JustifiedTrope considering even Miguel [[EvenEvilHasStandards had problems with the cult sacrificing a child]].
* ArtStyleDissonance: The art is pretty, but much too cartoony for a horror game.
* BloodlessCarnage: Characters are shot in the head, stabbed, dropped from high places and tortured without any blood splatter, though John's model changes to reflect any bruises he gets.
* BrainsAndBrawn: Henry is the SmartGuy while Cooper is DumbMuscle.
* BuriedAlive: The fate of either John or Henry, depending on whose ending you choose.
* BigGuyLittleGuy: Cooper is the big guy and Henry is the little one.
* BittersweetEnding: In Johns and Coopers endings, John and Pauline are both immortal, but so is Henry. In Henry's ending, Henry wins and enslaves Pauline, but John finally got over his constant amnesia (including the part where he keeps forgetting his advanced martial arts) and is ready to take the fight to Henry.
* CellPhonesAreUseless: There's no signal at the station.
* ColdBloodedTorture: According to himself, Henry has killed John about 50 times in cruel and sadistic ways. He also mentions that John could do the same.
* {{Cult}}
* DrivenToMadness: PlayedForDrama with Boris, who went mad from losing his son.
* DecoyProtagonist: You start playing for Henry White, who seems like a nice guy who wants to help homeless people. At the end of the proloque however it is revealed that Henry is a serial killer who kills and tortures homeless people for fun, while Choke is an immortal who keeps coming back to life as a young man with no memories.
* {{Dedication}}: "This game is dedicated to those who live in the street and those who try to improve their situation, like Les Enfants De Don Quichotte in France."
* DepravedBisexual: Implied for Henry, with emphasis on "depraved".
* DisposableVagrant: Nor the police nor anyone else cares about the murders because the victims are homeless.
* EvilRedhead: Henry.
* FourEyesZeroSoul: Again, Henry.
* FateWorseThanDeath
* GuideDangIt: [[ZigzaggedTrope Zigzagged]]. While there are moments that may be a little difficult for a player to figure out, if you play with items enough, eventually the game will give you a hint. However, some of these hints when you view them in order may seem out of context. Eg, the game tells you you need something that uses batteries, when the next hint does not tell you what you need them for.
* HeelFaceTurn: Cooper may turn on Henry [[MultipleEndings in one of the endings]] as revenge for shooting him.
* HollywoodNerd: Henry White appears this way at the start of the game.
* ImmortalityHurts: John's deaths are only temporary and don't leave marks on his body, but he can still feel pain. Henry takes full advantage of this and tortures him for years.
* JerkJock: Cooper is a refreshing aversion, until [[DoubleSubversion you realize what exactly has happened after he rescued Henry White from a cult]]...
* JerkWithAHeartOfJerk: Henry. He's a sociopath and murder, but he did spend his youth helping the homeless, right? Well, no, he burned and tortured them. But at least he's always been a good friend to Cooper, his HeterosexualLifepartner with quite some HoYay... until he shoots him with neither hesitation nor remorse.
* {{Leitmotif}}: Henry has a haunting tune that he whistles frequently.
* MultipleEndings: There's one for Henry, John and Cooper. The player can choose between them during the final confrontation.
** Cooper: [[spoiler:Cooper throws Henry into the well as punishment for being betrayed. Cooper and John leave on amicable terms, while John and Pauline start their relationship with "all the time they need". Henry wakes up surrounded by weapons, and eagerly tests his immortality by torturing himself.]]
** John: [[spoiler:John brands Henry to ensure that he can keep track of his rival, and then throws him into the well. John wants Pauline to help him forget all this. Cooper wakes up to the sound of Henry's whistling.]]
** Henry: [[spoiler:Henry persuades John to save him from the well, only to stab him with a heated knife. Henry laments the deaths of his favorite toy and his bodyguard, but now has a new toy (Pauline) to play with. John wakes up, looks at his hand, only to realize that he still remembers this time. At the very least, he remembers HENRY.]]
* MistakenForPrankCall: Subverted. Cooper thinks that Henry's pranking him when he calls for help but then Cooper hears Chok talking and realizes that it's not a prank.
* NoOneCouldSurviveThat: Choke is shot in the head at the end of the prologue and is thrown into the back of Henry's truck, only to sit upright with a gasp.
* OhCrap: Henry's expression as he realizes [[CountingBullets he's out of bullets]], just when he's up alone against John.
* PayPhone: There's one at the station.
* PistolWhipping: Henry is knocked out by Boris who hits him with a pistol.
* PoliceAreUseless: The police do not give much attention to the events.
* ReallySevenHundredYearsOld: Turns out, John is an immortal who was born some time in the late 1400's.
* ReverseWhodunnit: You're told who the bad guys are in the prologue, the twist is why they do what they do.
* RoomFullOfCrazy: The very first scene in the game, shows walls painted with red color, possibly blood, multiple satanic symbols, and photos of multiple persons, with notes as "Torture" and "Dead?" Oh, and did we mention the flashes of screaming faces and their respective screams.
* SerialKiller: He kills homeless people. It revealed to be Henry.
* ShoutOut: Later in the game, when Henry drinks the immortality elixir, he brings the elaborate cup they made John drink. John says "[[IndianaJonesAndTheLastCrusade A simple carpenter's cup will do.]]"
* StartOfDarkness: Henry snaps after being humiliated in the prologue, leading to the events of the main game.
** However, he and Cooper are heavily implied at the end of the prologue to have been the ones burning homeless people.
* SdrawkcabName: [[http://en.wikipedia.org/wiki/Frida_Kahlo Olhak Adirf]].
* SmartPeoplePlayChess: How does Henry avoid getting executed by a cult? Argues that because he is smart, they shouldn't kill him. How do they test his intelligence? Why... ask him what moves he should make in Chess. Justified in that Henry was specifically ''asked'' if he played chess before.
* {{Unwinnable}}: Averted - It is impossible to get a game over.
* WealthyPhilanthropist: Henry White, the heir to a wealthy family, spends his free time and money fighting homelessness and swears to dissolve the family business to help charity. This attitude doesn't last past the prologue.
* WhoWantsToLiveForever: Take the immortality potion without mercury and you're doomed to lose your memory every time you die.
* {{Workaholic}}: Boris was one in his backstory.
* YouHaveOutlivedYourUsefulness: Henry's tendency towards this is used to try and turn [[spoiler:Cooper and Dr. Yesterday]] against him. Henry shoots them both before it can really happen.
** That said, [[HoistByHisOwnPetard it does contribute to Henry's]] [[CountingBullets running out of ammo]].
