In the first two Resident Evil games you were tasked with dispatching enemies that were largely animalistic, the Zombies craved flesh, the hunters were aggressive killers, the Tyrant/Mr. X operated under commands and William Birkin's mutated form was killing to survive, rather than hunt. For the third game, Capcom decided to change things up a bit and pit you against an intelligent, brutal killing machine and thus, Nemesis was born. Nemesis is a bio-organic-weapon engineered to be the ultimate hunter, he is intelligent and can make decisions for himself, he can wield weapons (in the form of a rocket launcher strapped to his arm) and possesses regenerative abilities meaning you can't actually kill him. Worst of all, he is fast and whereas in previous games if you were overwhelmed you could just leave the room, he will chase you from room to room. Most unsettling of all, whenever you encounter him the screen will go negative and you will hear him utter "S.T.A.R.S." in a demonic growl.The Nemesis haunted the dreams of gamers around the world, never had they fought a creature so aggressive and relentless who could not be bested. If you were lucky you could knock him unconscious long enough to run away but he would always come back and always when you least wanted him to. Trying to run from him with RE's notorious tank controls was an absolute nightmare and further added to the terror you would feel when you heard his deathly voice.
