Resident Evil: Operation Raccoon City will include a multiplayer mode entitled "Nemesis Mode," exclusively for Xbox 360. Now, don't go thinkin' this DLC is free or something crazy like that. Nemesis Mode will be available at launch, on March 20, for 320 Microsoft Points ($4).
Nemesis Mode has the USS verses the Spec Ops in an eight-man battle with someone able to control a Nemesis. While one team tracks down a control unit, the other can "give the Nemesis orders to destroy the opposition." As with all things "exclusive," we don't know how long it'll take before this multiplayer mode infects other platforms, but we're sure not even Capcom can contain Nemesis.
