The newly released Battlefield 3 beta has been hacked to support 128 player games. Sadly for those participating in these mega wars, they will more than likely find themselves banned by EA games.
The Battlefield blog has print screened one of the hacked servers as you can see below (please note the name given to the server is quite rude):
Gamers will have the chance to sample both Operation Metro and Rush maps in the beta. They can also play in 32 player mini wars online, anything beyond this number is indeed a hacked server.
EA has confirmed that gamers joining these servers will have their EA accounts banned.
