The concept that makes GTA what it is, is now in 3D in this release.

The game puts you in the shoes of a vicious, albeit novice, criminal. Traditionally, your missions center on the gangs inhabiting the city - each one always has jobs for you to perform, and your prosperity as a criminal depends on your ability to manipulate each gang. Ice a few members of one gang, and you'll gain its rival's favor. Jobs range anywhere from running dope and taking out rivals to sabotage and kidnapping.

Strictly for the matured.
