Please report all these issues/hackers to PSN 800-345-SONY and Rockstar http://support.rockstargames.com/anonymous_request
If enough people report and complaint about these hackers/modders, Im sure these low life will be banned and they would need to purchase a New Ps3.
I have seen hackers in 4 on numerous occasions 1 guy had the wire looking globe from the park surrounding him and he was shooting flames and 1 was flying an airplane shooting flames and both players were invicible as well as 1 guy was driving the infernous with underglow and he could also make the car fly as well as change the colors of the car at will Dont tell me people cant hack the game
yes it has gotten pretty bad,the best thing to do to avoid this is try and get a few friends playing in the same game with one hosting it from the start that way when one comes in,it will make it easy to kick them out..
i always hated the kick feature but for this it is useful...i also sometimes will use a UDP flooder and lag the whole game out and it kicks everyone from the game besides me then i can invite my friends back in and we will have the invincible cars and heli's...LOL
