343iBot Posted June 29, 2012 Report Share Posted June 29, 2012 From Community Customs: Community Customs continues by running our popular Proving Ground again this week, where we'll test maps and game types that aren't quite ready for Primetime. Bring the maps and game types you've been working on, and we'll help you get them polished and ready to be played by the masses. Sign up at the link below!
