* DevelopmentGag: [[JokeCharacter Tofu]] was used during development to test the game's hit detection.
* DummiedOut: The first encounter with the Licker was supposed to start with it dropping the head from the decapitated corpse in the hall. The staff changed their minds late in development, perhaps for fear of censorship, but decided to simply cut out the cue for this and leave the head stuck up on the ceiling. It's normally out of the the camera's view since the game was meant for a 4:3 picture ratio, but playing the game on an emulator with widescreen support reveals that the head is still present.
* KeepCirculatingTheTapes: It's virtually impossible to find any retail copies of PC-DVD version of ''Biohazard 2'' through any store in this day and age.
* NoExportForYou: The PC-DVD version of ''Biohazard 2'' by [=SourceNext=] was released only in Japan, which is unfortunate since the PC-DVD version of the game combines both Leon's and Claire's games into one similar to the UsefulNotes/{{Nintendo 64}} and UsefulNotes/NintendoGameCube ports instead of having two separate CD-[=ROMs=] and fixed many of the compatibility issues on Windows XP.
* PlayingAgainstType: Claire's voice actor, Creator/AlysonCourt, starred mainly in children's shows (including several ''Franchise/CareBears'' movies and ''Series/TheBigComfyCouch'') before starring in a dark, gritty {{survival horror}} game.
* RelationshipVoiceActor: Paul Haddad, Creator/AlysonCourt, and Jennifer Dale (the voice actors of Leon, Claire, and Annette, respectively) all previously voiced [[WesternAnimation/XMen Quicksilver, Jubilee, and Mystique]].
* UrbanLegendOfZelda: ''Electronic Games Monthly'' ran a Trick of the Month in an issue saying that entering ''[[Franchise/StreetFighter AKUMA]]'' into the computer terminal instead of GUEST would unlock that character for play if the game had already been completed six times with A ranks using only the knife or handgun. Akuma's presence in ''VideoGame/StreetFighterEX'' made the screenshots possible to fake.
* WhatCouldHaveBeen: ''Resident Evil 1.5'', the original version of ''VideoGame/ResidentEvil2'', was scrapped due to the developers being displeased with the way it was going.[[note]]A fan-compiled, playable ISO image of ''Resident Evil 1.5'' can be found online, if you know where to look.[[/note]] While it's similar to the game that would eventually be released, it does contain some notable differences:
** Leon's very first character design was of a shorter-haired, tougher-looking guy. He was changed because he too closely resembled Chris Redfield.
** The main female character was Elza Walker, a college student and motorcycle enthusiast who returned home to Raccoon City on vacation. She would be {{retool}}ed into Claire in order to have a greater plot tie with the first game.
** Robert Kendo, known here as John, and Marvin Branagh were to play much larger roles in the game, acting as supporting characters for Elza and Leon, respectively. In addition, Ada Wong was simply a researcher, and Chief Irons was a sympathetic character rather than a villain.
** There were going to be two different final bosses (Golgotha and Salem) that each respective character would fight near the end of the game. Also it was optional to save one, all, or none of the secondary characters; see [[http://www.youtube.com/watch?v=C6KCS12IT88#t=6m12s here]] for more details.
** The police station was going to look much more modern in appearance and awash with {{bad blue lighting}}, as well as having a few more varieties of zombie cop (at the expense of most varieties of zombie civilian), including the infamous fat zombies that didn't show up in a released game until ''VideoGame/ResidentEvil3Nemesis''.
** The zombies themselves had far fewer textures and polygons. This would allow ''even more'' of them to attack you at once. The final version added more graphics to the zombies at the cost of having only seven appear in one room at a time.
** There were several new types of enemies created for ''1.5'', including spider-human hybrids, à la the Chimeras in the first game, mutated gorillas and their offspring, as well as offspring for the giant alligator in the sewers.
** There were different types of armor that Leon and Elza could equip. Furthermore, they would [[ShowsDamage show damage on their character models]] as they got attacked by zombies and other creatures.
** There exists concept art depicting Annette also having mutated into G like her husband, although this allegedly didn't progress any further beyond a preliminary idea; as William Birkin's role was mostly unchanged in the final version from that of ''1.5'', it's unknown what would've led to Annette's mutation or what Annette G would've done post-metamorphosis.
** Unlike in the released game where Umbrella are still operating, the company had folded by the time ''1.5'' had begun since the surviving S.T.A.R.S. members were spared from the CassandraTruth and were believed when they told everyone what happened at the Arkalay Mansion.

* The cinematics are all done with {{stop motion}}, believe it or not. The characters that appeared are hand-created figures performing stop motion animation, which were combined with full motion video with computer graphics tools. According to WordOfGod, Ada does not appear in any of the video cutscenes because her figure was not finished on time.
* The version of ''Resident Evil 2'' available on the [=PlayStation=] Store as a [=PSOne=] Classic is the ''Dual Shock Edition'' (which includes Extreme Battle and Arrange modes) for all regions, marking the first time Europe got the [=PSOne=] ''Dual Shock Edition''. Because the game is a North American import, it requires a 60hz TV set up to display properly.
* When Angel Studios (now Rockstar San Diego) was first figuring out which UsefulNotes/PlayStation game to port over to the Nintendo 64, they had two options. One of the options was rejected because the developer didn't want to ruin the product on a cartridge based system, so Angel Studios had to go with ''Resident Evil 2''. What was the other game in question? ''VideoGame/FinalFantasyVII''.
* Around the time that the game was being made, Capcom was also making ''VideoGame/MegaMan8''. Apparently, Sony demanded that ''Mega Man 8'' needed to be in 3D. Capcom retaliated by threatening to not release ''Resident Evil 2'' on the [=PlayStation=], which got Sony to back off.
