Over the weekend it was revealed by the Battlefield 3 Blog that the beta had been hacked to allow players to play different game modes with support for up to 128 players. The Battlefield 3 beta currently features support for a maximum of up to 32 players in Rush mode on the Operation Metro map.
Dice has said that they have “tested out Operation Metro on conquest with 64 and 128 players, and can confirm their existence, albeit, the 128 player server lagged considerably.”
If you decide to play on these maps you can risk you’re account being banned as Dice has said that playing on the hacked servers “can cause your account to become compromised, stats to be altered or other issues to arise which may lead to having your account to be banned by EA.” In addition, horrifyingly, “if your account does get banned it means any other EA game you have on your account would also be unavailable.”
So not only will you risk you’re account being banned, but also any games that you have on that account will become unavailable for you to play. It is good to hear that at least dice has tested with 64 and 128 players and maybe we can expect that in the full game or in an update.
