It's a game called Grand Theft Auto. It's got to be finished by the end of June, so they're involved in some pretty hard work in here. It's all about a car chase through the streets of a fictional, probably American city. Here are some of the maps they've been working on. Dave, just explain the point of the game.

Well, it's a mission-based driving game where you're basically driving around the city, stealing cars, running over pedestrians.

Pretty change stuff there. Well, yeah. What have you been contributing?

I'm working on a radio station at the moment, the hip hop station. There's a variety of different stations in each car.

That you go into. So you're not just taking it all off a CD, you've actually.

Composed it. No, everything's composed in-house.
