Murphy Seeker
Murphy Seeker was a member of the UBCS sent into Raccoon City. When encountered by Jill Valentine, Murphy had been infected with the T-Virus after being bitten by a zombie, and was well on his way to becoming one himself. Before fully turning, he pleaded to be killed and got his wish.
Comments
Because several key events of Resident Evil 3: Nemesis depend on what the player does and in what order, some things may turn out differently. Case in point, Murphy Seeker can either be shot by Nicholai Ginovaef without a hint of mercy, or by a very remorseful Carlos Oliveira.
Murphy is absent from Nemesis by S.D. Perry, but the concept of Carlos having to kill a teammate who is regressing into a zombie is still there in the form of Randy Thomas, another UBCS member unique to the novel.
