Thought about it... which R6 you talking about though?
ha true. If its RSV2 then yeah, you won't have trouble finding a room in multiplayer or coop Terrorist Hunt (not sure about coop story).
I havent tried RSV1 in months, but when I did there were lobbies open. Problem with those is that everyone seems to like long games that you cannot join in progress. SO you should get into a game, but it will take much longer then RSV2.
