Our Battlefield 4 hack is currently UNDETECTED by PunkBuster.

TMCheats Battlefield 4 does not have any PunkBuster detection by far.

For the first time,EA implemented 2 anti-cheat system on Battlefield 4,which are PunkBuster and FairFight

Since PunkBuster is client-sided(which mean you will need to install PunkBuster services on your computer)
TMCheats is able to "bypass" their detection...and keep you safe from PB detection.

However,the latter one(FairFight) works differently than the former one(PunkBuster).
FairFight is server-sided anti-cheat which we have no control over it hence we couldn't bypass it for you.
Only you can bypass the FairFight by playing/acting like legitimate player as they track your gaming behavior.
