Piazza is basically for close range combat, basically your smg's, ar's and possibly shotguns but their really isn't a stop to snipe unless your a trigger happy quick scoper lol. Liberation on the other hand is made for CAG wide open spaces lots of trees, excellent for Snipers. I believe for the regular Xbox People it comes out in March since we'll get another map this month. You could play it in the Elite playlist but you'd have to play other gamemode(s).
