A first-person prototype was produced, and initially featured a supernatural, psychological Japanese horror style similar to Sweet Home, before opting for an American zombie horror style influenced by George Romero films. During production, Mikami discovered Alone in the Dark (1992), which influenced him to adopt a cinematic fixed-view camera system. Mikami said that, if it wasn't for Alone in the Dark, Resident Evil would have had a first-person view instead. Mikami was initially reluctant to adopt Alone in the Darks fixed-view camera system, saying it "had an effect on immersion, making the player feel a bit more detached", but eventually adopted it because the use of pre-rendered backdrops allowed a higher level of detail than his fully 3D first-person view prototype, which "didn't get along so well with the original PlayStation's specs." A concept art claimed to be of the original first-person prototype has been available since the 1990s, showing more similarity to Doom rather than Alone in the Dark. A first-person perspective was not used again for the mainline Resident Evil series until Resident Evil 7: Biohazard (2017). A later prototype featured cooperative gameplay, but this feature was eventually removed, as Mikami said it "technically...wasn't good enough." Early footage of this co-op prototype was revealed in 1995. At this stage of development, a local co-op mode was present, along with different outfits. A later demo made for the 1995 V Jump Festival presentation in Japan featured real-time weapon changes, with the co-op mode removed and rudimentary character models and textures. An early 1996 preview in Maximum Console magazine featured a graveyard and a slightly different version of the final boss. The graveyard, which was removed from the final game, eventually made it into the 2002 remake. Also featured in the game until late in development were guest houses and a tower, which were replaced by the guard house and the lab respectively. Another feature that was removed from the final game was the real-time weapon changing, from the earlier 1995 V-Jump demo. Capcom did not use any motion capture in the game, despite having their own motion capture studio; instead, the animators referred to books and videos to study how people, spiders, and other animals encountered in the game move. In pre-production, other characters were conceived. Dewey, an African-American man, was intended to perform a comic relief role, while Gelzer, a big cyborg, was a typical "strongman" character. Both
