* In a 2024 UsefulNote/TwitterX [[https://twitter.com/LastStarfarer/status/1788298063984877819 post]], as part of an indie game developer trend, Yuri Stern posted several works that inspired the game; while the original trend asked for three inspirations, they used a DrosteImage to include several others. These works include:

----

** The replika model KNCR (Kranich) is TheGhost in the finished game, only mentioned in a single document, but at some point she was going to be part of the main replika lineup and have a corrupted enemy type. Like the others, model data for both Kranich versions exists in the files. Based on her appearance (namely the distinctive black dots on her forehead), it can be inferred that Kranich was another [[PsychicPowers bioresonant]] replika unit, like Kolibri and Falke.

** The first teaser included a character called Rebecca that showed up in some scenes. In the final game she only appears in a partially visible photo and in the medical database.

* An unused machete EmergencyWeapon.
* Enemy data and animations for [[TheUnfought Adler's corrupted form]], and an unfinished boss arena for him based on Nowhere's razor wire mazes.
* A few unused rooms for the ''Penrose'', including a TowersOfHanoi puzzle for operating the reactor (serving as a more complex retread of the hospital wing's water tank puzzle).
* Inventory art for puzzle items that might've had story significance, such as a tooth implied to be Ariane's.

** Adler's corrupted form was originally intended to be fought as a boss, and [[DummiedOut he's still present in the code]]. His animations involve hiding the knife behind his back and [[ShmuckBait beckoning the player to come closer]], before suddenly lunging to attack. Based on some related map assets, Adler would've been an AdvancingBossOfDoom chasing Elster through a monofilament wire maze.

* FanNickname: Replikas that don't constantly reinforce their identities will eventually begin to recall their human template's memories or even revert to their original human personality, in a process one file calls "Persona degradation." Fans almost immediately nicknamed this process "rampancy"/"going rampant," after a similar process that happens to artificial intelligences in the ''VideoGame/{{Marathon}}'' and ''Franchise/{{Halo}}'' series.

** Early plans for the game found [[https://rose-engine.tumblr.com/post/120858734562/collection-of-mays-screenshotsaturdays on the developers Tumblr]] indicated that originally the game was planned to be 2D before switching to PS 1-style 3D models.

** [[https://www.youtube.com/watch?v=OexLgluGHWo Within the data files is a Machete]] which was DummiedOut. With unlimited ammo it would serve as an EmergencyWeapon in case all guns were depleted.
