A companion app and website for Star Wars: Battlefront has been released today, allowing you to earn in game credits a week before the games release. Called Base Command, you can check it out here or download it for iOS or Android.
Base Command is a board/card game hybrid with a surprising amount of depth including unlockable cards (some of which are tied to in game Battlefront achievements) and deck customisation. There are certainly worse ways to spend your time and definitely worse companion apps.
Star Wars: Battlefront arrives 17 November for PS4, Xbox One and PC.
