Its the same map but with a all new story. I really like GTA and I thought it was a real cool add on. But I looked all threw the menu and cant find any thing.
i noticed when i played today, if your on your xbox dashboard and you go to play gta4, press Y and you have other options, see if theres something in there that may be showing up differently than for me, like an options for that secondary storyline whatever its called.
