You can play the full game but with DLC maps locked.
EA Access subscriptions is growing and getting better every month. After the addition of Mirror’s Edge Catalyst there’s now a full version of Star Wars Battlefront for you to play on Xbox One.
It’s worth mentioning that Electronic Arts offers a full access to the standard edition of the game. There were four DLC packs released post-release through season pass and single purchases. You’ll have to buy them to visit Death Star or Scarif, the planet from Rogue One.
EA Access is a subscription separate from Xbox Live Gold. Subscribers are allowed to download a variety of games available through The Vault.
