Rockstar will be including a drug-dealing mini-game in Grand Theft Auto: Chinatown Wars on DS.
This will let players shift cocaine, heroin, weed, acid and downers in different areas to turn a profit, according to Edge magazine.
"We wanted to have a drug-dealing mini-game in lots of the GTA games," said Dan Houser, big boss of Rockstar. "It works well with what GTA is, with driving around the map, and it gives you another thing to think about - another layer or piece of the puzzle to keep you motivated."
Houser said the drugs will "intersect" and "work with" the main story, although will be largely included as a way to make heaps of money. Just like in real-life.
Sounds rather a lot like that fiendishly compelling PC freeware game Dope Wars to us.
Grand Theft Auto: Chinatown Wars is due out on DS this winter.
