Forum:The angelic ruins

hey everyone. i recently downloaded mad moxxi and my roommate and i are having someserious trouble with the angelic ruins (especially the 4th wave in the 5th round). we found some great spots in the gully and hell-burbia for sniping or just getting out of some trouble, but can't seem to find a good spot to set up in the AR. Just wondering if anyone has found a spot that seems to give you an advantage during the fights?
