BIOHAZARD 1.5 differed drastically from the released Resident Evil 2 in terms of plot and gameplay mechanics, enough for it to be dubbed with a different name by developers such as game Producer, Shinji Mikami. Its plot followed the same basic outline as that of Resident Evil 2, and featured a zombie outbreak in Raccoon City two months after the events of the first game. Development of Resident Evil 2 began one month after the completion of its predecessor in early 1996, and the first footage of the game was shown at the V Jump Festival '96 in July.
