Welcome to Drug Dealer Simulator. There's a lot to know to be able to make it from a small-time dealer to major kingpin, but hopefully this will help get you started.
Completing the Tutorial
Grab your backpack from on top of the cupboard, get the keys out of the cupboard, unlock the door, and head down the stairs. Feel free to explore, you're not on any time limit. When you're ready to start dealing, follow the blip on your map/compass.
You'll meet up with Eddie and catch up. He'll tell you to go pick up your first dead drop at the supermarket. Head over to the blip on your map/compass and get the drugs from the drop point. It's marked with a symbol that you'll soon become familiar with.
You should have a few orders from your clients - accept them. Head back downstairs and outside. Follow the blips on your compass/map to find your customers and deliver them the drugs.
Next, you need to place another order for some more drugs from Eddie - go ahead and order up 10g of Amphetamine and 10g of Marihuana.
