Star Wars Battlefront Beta extended - get blasting!
And it's pretty fun right? The wave based mission is a great primer, though the only available difficulty level is way too easy, and running around capturing pods from evil Imperials (or Rebels) is ideal for quick games. The real meat though lies in the major assault on Hoth, as you desperately try to survive as the rebels or pretty must kill everyone as the Empire. Seriously, I only saw the Rebels win once, some balancing has to be done.
The same content will be available for the extended beta, with an extra day added by EA and DICE to really stress test those servers. That meahns you may experience some lag or spotty connectivity but know that it's all in the name of science... or at least a way to ensure better performance when the game launches properly in November.
