There was that forge playlist which had new maps, but unfortunately they removed it. Hopefully they add some of those maps to Team Slayer Pro when it comes out. The doubles playlist has some good forge maps now.
Also, Team Action Sack would be amazing. And don't be deterred by these "board regulars" who like to come in and **** on anyone asking questions, or people who are not a member of their obviously elite status.
