I'm more of a far-off admirer of Battlefield than someone with an active interest in it. I have my binoculars trained on it and I can tell it's beautiful, it's big, and it looks like a lot of fun. But I have Arma 3 and Counter-Strike: Global Offensive (I've been casually playing CS:GO with some friends for the past few evenings), and there's no more room for another shooter where I have to know things about the guns. For those of you who really want to play it, you'll be able to on October the 1st for free: that's when the open beta will allow everyone to hop on Conquest mode on the Siege of Shanghai map.
Which looks like this.
But this being Battlefield and EA, they have another beta as well. A pre-emptive splitting of the community? They're getting their work done early, I see. The "Exclusive Battlefield 4 Beta" is for Battlefield 4 Digital Deluxe pre-orderers, Battlefield 3 Premium members, and the people who bought Medal Of Honour: Warfighter (remember that?). It also starts "early October 2013" according to the FAQ, but there are no other details. It might be a different map, or it might be super-early access to the open beta, but I can't imagine it's the second as both betas seem to be starting at the same time.
It'll be out on Oct 29t in the US, and 1st November in the UK. Because of reasons.
