Not a private match - but lockdown. Need 2 teams of 4 - we try to match up - if successful we chase the mountaintop quest step "The Third Wave" (triumph - in pursuit of honor). Cheese tolerant folk only - priority to clan members.
The game creator, cadarnloz, should send out invites 5-10 minutes before start time. If you don't receive invites, the creator may have left so start inviting each other through xbox/psn/pc on your own.
