The Xbox 360 version of Resident Evil: Operation Raccoon City has an exclusive multiplayer mode.
Nemesis Mode, an Xbox 360 exclusive competitive multiplayer mode, sees the USS compete against the Spec Ops in an eight-player high score battle.
The twist is you're able to control Nemesis, the big, bulky bad guy from Resident Evil 3. To do so, track down the control unit, then order him about.
Nemesis Mode is day one DLC, and costs 320 MS Points.
