The island needs food to survive. There is a farm close to Slum ville, half way to the beach, where they are growing all kind of vegetable. The place is guarded by some military to secure the area against the ones who want to steal the vegetables and resell them to the shops. Beware to not piss-off the owner!
I also heard that there are some cannabis plants arounds and that you can grab some and sell them to the Punks at the Cyber building.
We may program the car to be drivable later on in the development.
