Rockstar Games has released the third gameplay trailer for upcoming DS title Grand Theft Auto: Chinatown Wars. The clip's called "Dealing and Delivering" and shows hero Huang Lee flexing his entrepreneurial skills.

One of the major features of Chinatown Wars is the drug dealing minigame. It's a bit like the Dope Wars game you may have played on your graphing calculator in high school. Basically, you buy drugs from one group and sell them to another group that wants them more. There's six different types of drugs, all coveted to different degrees by the various gangs of Liberty City. To keep things interesting, some of the drug deals will be set-ups by police and you'll need to flee their pursuit. Getting caught in possession with drugs is frown upon by video game cops as well as real ones.

Chinatown Wars will be released on Tuesday, March 17th for the DS. You can check out the previous two gameplay videos for Chinatown here and here.

Update: Huh. Rockstar just sent us an email that they've taken down the video. Not sure what the story with that is.
