You can start playing Star Wars Battlefront on Xbox One right now, if you have EA Access.
The Star Wars Battlefront EA Access trial is now available for all. If you’re an EA Access subscriber, head to the game list and click on the Battlefront tile.
This will take you to the store page and allow you to download the less-than-20GB file. This is the full game, with everything available to you for ten hours.
All your unlocks and saves transfer over to the full game on launch, if you get it on the same platform. You also get a 10% discount if you go digital.
