Petscop is an unreleased game, apparently developed in 1997 for the PlayStation 1 by a company named Garalina. The game was never finished and was never released to the public.
The game starts off innocently enough; in a friendly environment with a cheerful atmosphere. The primary gameplay revolves around "catching" creatures referred to as "Pets", somewhat similar to Pokemon. In order to catch Pets, the player must solve various puzzles, such as using a treadmill or pushing a bucket to a certain area. Despite the fact that they are called "Pets", the game use words such as "somebody" and "someone" to refer to them, both words which are usually used to refer to humans. This could hint at a connection between Pets and humans/children. According to the sign at the start of the game, Petscop was meant to have 48 Pets in total. There are 6 pets in total in the Even Care. It seems that the original game planned on containing 8 levels (or "homes") with 6 Pets in each level. After inputting a "cheat code" mentioned in the manual, however, the game takes a dark and frightening twist, with plots inspired by real life child killings that happened as a result of rebirthing therapy.
The menu of Petscop contains the usual suspects: Resume Game, Options, Pets, Quit Game. But it also contains a curious option called "Book of Baby Names". There is no consensus what the meaning of this option is. It’s random nature might indicate a clue regarding the names of characters in the game. It could also be a reference to adoption, where the new parents will often rename the children (such as Candace Tiara Elmore being renamed to Candace Elizabeth Newmaker who died). In Petscop 6, Paul shows us that "Book of Baby Names" does nothing upon selecting it. He guesses that at some point you would be able to name your Pets, and the Book of Baby Names would give you name suggestions. This further strengthens the connection between Pets and humans/children, as generally you wouldn’t name your Pet a human name (although many people do).
The game frequently references the "rebirthing therapy", a highly dangerous form of therapy that is meant to treat children with reactive attachment disorder. The most famous case of rebirthing theory is the death of Candance Newmaker, a 10-year-old girl who was suffocated during a rebirthing therapy session. The game has frequent references to Newmaker.
It is disputed whether Paul plays this on an actual PS1 or an emulator on his computer. Although he seemingly references some physical copy of the game, it is technically possible to put game emulation files on a disk which can then be played on a computer. Paul can occasionally be heard pressing buttons in the videos, but it is possible he using an emulator with a PlayStation 3 controller or another controller.
The meaning of the word "Petscop" is still unknown and/or under discussion. The most obvious theory would be a combination of PETS + COP, as the goal of the game is to pursue or trick pets so that you can "catch" them.
Another theory: The word "scop" has ties to meanings such as scold, scoff, abuse, derision, mock. If "Pets" are related to humans or children, this could be a further connection to the child abuse themes in the game.
It could also be a misspelled version of the word "Petshop". When Shadow Monster Man is writing his sentences in Petscop 6, he frequently misspells words. Since this would have to be programmed deliberately, Misspelling may be a theme.
Another Theory has been going around by the User "PetscopTheory43" on the Petscop Community from Amino. In this one, Rainer created the Game to mentally destroy Paul with the Events of "Candace Elizabeth Newmaker". Why Rainer would do that is still a Mystery.
- In spite of the fact that the game was "released" in 1997, the game references events that occurred in 2000 and beyond. This can either mean that the game was altered and the copyright date was not changed, the game predicted future events, or there is an "entity" inside the game that is aware of the events that occurred, and altered the game accordingly.
