In addition to its free DLC giveaway for the Battlefield series, EA is also extending additional bonuses for EA Access subscribers in the form of Battlefield Hardline Premium.
Premium is basically a fancy word for "Season Pass," as it includes all of the DLC and some nonsense bonuses like early access and microtransaction deal sweeteners. Since the service is only available on Xbox One, players just need to load up the listing for Premium or load the Premium app with an EA Access sub and they're good to go.
Origin Access, the confusingly different PC service, also has a Battlefield 4 Premium offer for subscribers.
