The trial limits the number of single-player missions you can do, but everything in multiplayer is available. Servers are live now, and any progress you make will carry over to the full game when you buy it. The trial also includes support for enhanced graphics on the Xbox One X.
Star Wars Battlefront II releases on November 17 for PlayStation 4, Xbox One, and PC. If you buy the Deluxe Edition, you'll get to play the full game early starting November 14.
