Ok. So I want to mod GTA IV. The MAIN things that I've like that I've seen around the block are flying cars and shooting rockets out of all weapons. As far as I can gather, I can't mod the good ole' Halo way huh? That would be using the Xport 360 and Hexing etc. And people mention 'Flashing'. So in order to mod GTA, what must I do, oh mighty forum ninjas!? *Please leave flames at the door. I'm just asking for help, and in one spot! Thanks!
