Resident Evil: Operation Raccoon City delivers a true third person team based shooter experience set within the dark and sinister Resident Evil universe and a reinterpretation of the events depicted in Resident Evil 2 and Resident Evil 3. Zombies and Bio-Organic Weapons (B.O.W's) add to the mix as players not only compete against an opposing squad but also tackle this third unpredictable element, creating a brand new style of gameplay and breaking the conventions of traditional team based shooters.
It is September 1998 and the action centers once more on the ill-fated Raccoon City and the horrific consequences of the deadly T-virus outbreak from the Umbrella facility. With a cover up required, Umbrella orders an elite team into Raccoon City to destroy all evidence of the outbreak and eliminate any survivors. Hearing of this plan, the US Government dispatches its own special forces to uncover any evidence that exposes the cause of the viral infection and Umbrella's actions. Players take on the role of an Umbrella Security Services soldier (U.S.S.), competing alone or in four player co-op in a battle against all the competing forces at play in Raccoon City.
