Rockstar Games officially released the first teaser trailer for Grand Theft Auto IV. Scheduled to ship on October 16th, the game will be the first entry in the series for the Xbox 360 and the PlayStation 3. The trailer gives a brief, but detailed look at the updated look for Liberty City, and the focus this time appears to be on a Russian immigrant character. Beyond that, it is hard to get a feel for where Rockstar is taking the sandbox game series, particularly story and gameplay-wise. One can get glimpses of the product parodies that gamers have gotten used to for the game, but beyond that, the trailer does it’s job – whet gamer’s appetites for more to come.
