: You can purchase the base game or the Battlefield 3 Premium Edition directly from Electronic Arts. The Premium Edition includes all five expansion packs: Back to Karkand , Close Quarters , Armored Kill , Aftermath , and End Game .
: The game is available on Steam , which frequently offers significant discounts. Note that launching the game through Steam still requires the EA App to be installed and linked to your account.
: Unlike modern titles, Battlefield 3 uses a web-based launcher called Battlelog . When you click "Play" in the EA App or Steam, it will open your default web browser to manage your loadouts and join servers.
