Resident Evil Revelations will see a return to the survival horror gameplay of earlier series installments, with returning elements such as a limited supply of ammunition, and more emphasis on exploration and puzzle solving. As in Resident Evil 4 and Resident Evil 5, the game’s camera keeps an over-the-shoulder view from behind the playable character. The player may move the protagonist while aiming a weapon, and has the option to switch between a first-person and third-person perspective. A new item, the supply scanner, detects items hidden throughout the game’s environments. The game is set in 2005, between Resident Evil 4 and Resident Evil 5. It depicts the events shortly after the establishment of the Bioterrorism Security Assessment Alliance (BSAA), a counter-terrorism group introduced in Resident Evil 5. The story revolves around BSAA co-founders Jill Valentine and Chris Redfield, the protagonists of the first Resident Evil. Chris and his partner Jessica have gone missing, and Jill is dispatched to a cruise ship in Europe to investigate their whereabouts. On her mission, Jill is joined by fellow BSAA operative Parker Luciani. Settings in addition to the cruise ship include a port town and a snowy mountain.
