Resident Evil Revelations stars Chris Redfield and Jill Valentine, the game displays hallways reminiscent of the mansions of the original Resident Evil and Resident Evil 5. While most of the game takes place aboard the luxurious cruiser Queen Zenobia. Set mainly in Europe, Revelations sees the player characters through ravaged cities, ports, and snowy mountains. Jill and Parker are sent out by B.S.A.A. head Clive R. O'Brian to search for Chris and his new partner, Jessica Sherawat, who have reportedly gone missing during a mission. Meanwhile, Chris and Jessica are operating in a snowy mountain region, searching for evidence of the return of Il Veltro, a bio-terrorist organization responsible for the attack and subsequent outbreak in Terragrigia, an artificial aquapolis that was utterly destroyed on orders from Morgan Lansdale, director of the Federal Bioterrorism Commission. Jill and Parker find their way into the Mediterranean Sea, acting on Chris' last known coordinates. They find themselves taking a tugboat to a seemingly abandoned cruise ship known as the Queen Zenobia. On board, they find horrific mutants known as Ooze, victims of the t-Abyss virus, and are unable to locate Chris or Jessica. Instead, they find a dummy in of Chris and are knocked unconscious by an Il Veltro agent, stripped of their weapons, and separated. The story is divided into 12 chapters, which are often further divided into separate segments. It begins with Jill Valentine and her new partner, Parker Luciani, whom the newly formed BSAA have dispatched to investigate the disappearance of Chris Redfield. Jill's horrific adventures largely take place on an abandoned cruise liner, though the game also features several other locations and follows other characters at various points in time, including Chris, Parker, Jessica Sherawat, Keith Lumley, and Quint Cetcham..
