The lastest issue of GamePro to hit the shelves has given an incite into Grand Theft Auto IV's untold changes from past GTA's. Although they have seen the same missions as past reviewers and previewers have seen and played, only they have released some important snippets of information not before mentioned:

• Billboards can be seen advertsing "Shark Credit Cards," "Pirate Music" and "The Whiz" (The Whiz being the type of phone Niko uses.)
• The HUD is described as "minimalist to its core." There is a mini-map, a "low-key" cash counter, and they say that the HUD in general looks more clean than in previous GTA games.
• Ammu-Nation no longer exists. We've heard about the new ways of acquiring weapons, namely from Little Jacob. GamePro is the first magazine to confirm that Ammu-Nation has been dropped.
• The rocket launcher will return (obviously, this has also been mentioned in other magazines but not explicitly confirmed)
• One of the female pedestrians screams "this sh*t is bananas!" from her vehicle. (Another quote we heard a while back)
• A fare meter appears on-screen as soon as Niko enters a cab, and the camera pans around it as it drives.
• The little green guy on crosswalks is crisp and clear.
• Clothing in GTA IV is described as "customizable, and also realistic."
• On shooting, the magazine states that: "the cover system borrows elements of Gears of War, and Rainbow Six: Las Vegas." It also says that "the aiming is a Resident Evil 4, over the shoulder style."
