This theater is the up to date theater for the DGL NA and EU competitive scene. It features a much more relaxed weapon class system compared to the default competitive theater. All classes can either have an AKM (INS) or an M16 (SEC). Weapon costs have been changed slightly as well to afford more utility and to try and allow a broader scope of strategy and tactics, with supply point balance.
