I was at the North east air field , with a friend. We where inside the east jail house , soon after we got there two guys where talking about how their hack worked. Apparently one of them was able to mess with the games files and allow him to make buildings ( and the anti hack software would not recognize the hack) see through making who ever is inside a trapped sucker. Soon after one of them got done explaining how it worked he described what I was wearing and what weapon I had . A minute later simply shoots us from the out side and completes his demonstration. Sadly I was not able to get a name to able to report him , but I thought I would let you guys know about this . This guys sounded so confident of his cheat that he was almost bragging , please spread this to let others know , and hopefully get to the people who can update the anti hack software to be able to detect this exploit. I am aware of the wall glitch and how it works , he did not just look through the wall. he was at the front door. ( door was closed as well) =( Thank you , have a wonderful night/day/ morning.
