There is several notable differences between the events portrayed in Resident Evil 3: Nemesis and Umbrella Chronicles Raccoon's Destruction scenario. One of the major difference is the absence of certain key characters from the Raccoon's Destruction scenario including Brad Vickers, Nikolai Zinoviev, Mikhail Viktor, and the later forms of the Nemesis-T Type. Certain events are also excluded from the Raccoon's Destruction scenario including Jill becoming infected with the T-virus and several Nemesis encounters later in the game.
