EA has announced a beta for Star Wars: Battlefront, which will apparently be open for everyone. This will take place in “early October” and contain three game modes, each of the two known ones with a single map. I expect that the third, unknown mode, Drop Zone, will also come with its own map, but it could technically reuse Hoth or Tatooine from Walker Assault and Survival, respectively.
If you are not a fan of online gaming, then EA is supporting single-player Survival mode. You will apparently require an internet connection, but it is unclear whether you need to have it active to play the offline mode, while you play it. Squadron Fighter mode will not be available in the beta, but Walker Assault has a bit of aircraft play, so you should get a taste of the controls (if you can ever find an available vehicle).
EA has also mentioned their Star Wars Battlefront Companion app. This will not be some kind of Commander Mode. It will apparently have a card game and social component. It will be available during the beta as a website, but the iOS and Android app will be “prior to the release of Star Wars Battlefront”.
The game will come out on November 17th, while the beta will be available in early October.
