Basically at 9PM EST, Rev usually does a Co-Op night on Wednesday's (that's tomorrow night). Right after, we like to test peoples maps to provide constructive feedback. Once all maps are done, we can play Warzone, Arena or whatever people want to do. If for some reason Rev doesn't do Co-Op, then we can start at 9 if there are enough people for the maps.

Reply back with your GamerTag and I can send a specific invite, or join with Rev and most of us will probably be talking and joining up there.
