Queues are experience based. You must have played a certain amount of Left 4 Dead 2 hours for each queue in order to join.
The Novice queue is meant for players who haven't really played pugs much.
The Intermediate queue is meant for players with a decent amount of experience playing pugs.
Joining the CEDAPug discord server is mandatory for this queue.
The Expert queue is meant for players who have been around a long time and want a quality game. Please be warned that you can be prevented from joining this queue if you are not able to play at the expected level.
If you're a regular long time player and you would like a particular player to be prevented from joining the expert queue, let us know.
