The game now can detect when u use the patcher and either prevent u from getting into a match or put u in a match with other "hackers" or OP bots whose shots simply deal huge damage and ignore armor. U get insta killed and can't even react.
I've played a couple of matches in both BR and CS using only ESP and the results are the same. Either super OP bots or speedhackers running around the map killing everyone and I could barely see them coming.
