Resident Evil 6 CO-OP

I'm sure we've all played a 2 player co-op game before, and it was only a matter of time before they started making games where 4 players can fight for the same goal.  If you've played Gears of War 3, the game even offered 5 player co-op in Horde Mode.  But now we have Resident Evil 6, and what better time to increase the CO-OP number to 6?  If you've seen the details of Resident Evil 6 it seems Online Co-Op will allow you and 5 of your most trust friends to fight and survive against the zombie horde!
