Update: Today, Capcom announced that there will not be a demo or public beta for Operation Raccoon City, prior to its launch. We misinterpreted a statement made by Mike Jones and apologize for the error. You can find the original post in full below.
Original post: Capcom's admittedly going out on a limb with Resident Evil: Operation Racoon City, its re-interpretation/re-telling of the events that transpired in Resident Evil 2 and 3. At just about every trade show this year, Capcom has brought out multiplayer builds of the squad-based shooter to get feedback and, at Capcom's Gamers Day 2011 event last week, producer Mike Jones revealed the public at large will get a stab at the game before its launch.
A public demo is planned for "early next year," Jones said, though he wouldn't offer exact details on the nature of the demo or when we should expect to be able to download it. That should give you plenty of time to come to grips with your new position as "the bad guy."
