''This is Resident Evil 3: Nemesis. If you were looking for the third movie, go to Resident Evil: Extinction.''

Resident Evil 3: Nemesis takes place before the events of Resident Evil 2 and two months after the Mansion Incident. It revolves around S.T.A.R.S. operative Jill Valentine trying to escape Raccoon City, surviving even more than she ever expected.

Jill eventually comes across a gigantic Umbrella bio-weapon called the Nemesis. This mutated creature can wield weapons and walk through doors and may appear anytime in the game.
