* HeyItsThatVoice:
** Leon S. Kennedy, Claire Redfield, and Annette Birkin's voice actors voiced Nightcrawler, Jubilee, and Mystique respectively in the 1990s ''WesternAnimation/{{X-Men}}'' cartoon.
** Sherry shares a voice with [[Literature/TheMagicSchoolBus Wanda Li]].
* 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 {{Nintendo 64}} port oppose having two separate CD-[=ROMs=] and fixed many of the compatibility issues on Windows XP.
** KeepCirculatingTheTapes: It's also virtually impossible to find any retail copies of PC-DVD version of ''Biohazard 2'' through any store in this day and age.
* 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.
* WhatCouldHaveBeen: ''Resident Evil 1.5'', the original version of ''VideoGame/ResidentEvil2'', which was scrapped due to the developers being unpleased 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]] It was similar to the game that would eventually be released, with the main differences being with the characters.
** 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, 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 zombie anything else), including the infamous fat zombies that didn't show up in an official 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, a 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.
* [[JokeCharacter Tofu]] was used during development to test the game's hit detection.
* 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 Word of God]], 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 for all regions, marking the first time Europe got the original PSX Dual Shock port, although as its a US import it requires a 60hz TV set up to display properly.
