Veteran monster mashers Jill Valentine and Chris Redfield return, both in the service of the Bioterrorism Security Assessment Alliance (BSAA), but not as partners. The game is set after Resident Evil 4 and before 5, in the wake of a bioterrorist attack in which the high-tech island city of Terragrigia gets obliterated.
Chris is paired with the flirty Jessica Sherawat, and Jill with Parker Luciani, a husky BSAA agent with a dubious Italian accent. The story plays out in TV-style, bite-sized episodes, each sandwiched between a "previously on Resident Evil: Revelations" recap and a cliff-hanger ending. It's a fun format for the compellingly hammy melodrama of Resident Evil tradition.
Much of the early game is spent playing as Jill or Chris in search of Chris or Jill, scouring the giant ship of horrors with your respective AI partner in tow. The new partners aren't hugely engaging--when you first meet Jessica, she's in shorts and ankle warmers, moaning about the cold on an arctic mission--but you're at least not responsible for their safety, since they can't be killed.
But, you wonder how much lonelier and scarier the game might be without the sidekicks. One of the most atmospheric portions is one that also most resembles old-school, haunted-house Resident Evil: Jill wakes up in a ship's cabin and has to venture alone and unarmed through the decaying luxury of the once-grand cruise liner.
