all i say is if they do mod it do not make a freeze gun or freeze lol
My take on GTA V modding. Is it will be possible, but if you do it online there will most likely be a banning system. Depending on how R* decides.
They could do it like it says in this article..
Or just flat out ban like Treyarch (COD) lol
Plus remember it will be a brand new game so they will apply patches to fix exploits for atleast 1 year.
