* Bellic, in need of firepower, calls up his associate Little Jacob, a Caribbean arms dealer.
* After calling to get firepower, Niko hails a cab to meat Little Jacob in an alleyway in Rotterdam Hill.
* Taxi rides can be trip-skipped.
* Niko pops in to an internet cafe, Tw@, to upload his CV to their website and surf the internet.
* GTAIV's web is accessible from any computer in the game.
* GTAIV's web is being kept under wraps, but told that its huge and very, very important.
* Unlike in previous GTA's missions can be interrupted.
* Castle grounds is a coast-side hangout overlooking The Statue of Happiness.
* Niko finds the guy with the missing memory stick with a group of people, he calls him to make sure its the right guy, when it is he puts 3 slugs in the back of his head and gets a 3 star wanted rating
* Any crime you commit will earn you a wanted rating. Instead of the cops just coming to where you are, the rating you are "awarded" translates to a visible search area. If you escape the search area your wanted level will flash and disappear. If you're spotted again though, the center of the circle changes to your position, therefor you have to start again.
* Police only operate in their own line of sight, if they can't see you, they can't stop you.
* Every street is named, police use this to track criminals down.
* For example, if you're in Star Junction (Times Square) in a Comet, you'll hear it on the police radio.
* Niko makes his way to Perseus after escaping the cops, Perseus is a menswear store. It's another clothing stores similar to the Binco stores in San Andreas.
* Multiplayer is still kept under wraps.
