As EvenBalance has added Battlefield 4 to the PB Setup v3.6 we are pretty sure that BF4 will have Punkbuster support. Therefore we have enabled support for BF4 from our side and are ready for the official release.
From now until the 15th October everybody can play the public beta! The first server with Punkbuster support are now online.
Furthermore another anticheat tool called "FairFight" got added to the server. You can find more information here: http://blogs.battlefield.com/2013/09/this-is-the-bf4-beta/
