A couple of days ago, we got a preview of Grand Theft Auto IV (PS3, 360) from The Official PlayStation Magazine (OPM). Today, we get the details from its Microsoft counterpart in publication, The Official Xbox Magazine (OXM). The gta4.net website was able to scrape out the new info from the publication and drafted the list of details that you guys might be dying to know.

We've paraphrased the whole list below:

• GTA IV is now 66% complete.
• Crosshairs pop up when Niko pulls out a gun. This could imply manual aiming in the game.
• When using your mobile phone, the camera will show a zoom-in panel of the mobile phone's interface at the bottom-right corner of your screen - allows you to view your address book for "jobs" and view other contacts.
• Exterior fire escape staircases are accessible; some meetings will happen high up in skyscrapers too - which could lead to you throwing people off the building from that height. Rawr.
• Hand to hand combat will feel "much more natural" and is currently being reworked.
• Camera angles can be changed even while in a car, but this feature is still being experimented on. Rockstar promises to make it more practical and functional though.
• Getting to control boats has been confirmed, steering them is "really nice." Huh?
• Central Park has also been confirmed to be in the game. The fictional name though hasn't been revealed yet.
• Dan Houser confirms that Liberty City in GTA IV is the biggest GTA city they've done so far. He says that details are a big thing.
• Houser also says that they're evolving how the radio works into the game, as well as how police behavior reacts to the things you do.
• The Rockstar developer studio in Scotland has been asking the NYC studio about more specific information on buildings and traffic flow in the Big Apple.
• There's an "Eastern European-sounding" dance station in one of the radio stations.
• Rockstar's "69" humor is back. There's a sign for a "69th Street Diner" and a building called "Twitchins" - that's GTA's version of Brooklyn's Domino's Sugar Factory. Easter eggs!
• "Fun ridiculous" weapons are also in the game because they don't really want to be too "naturalistic".
