Welcome to Drug Dealer Simulator. There's a lot to know before you'll be able to make it from a small-time dealer to a major Kingpin, but here's a guide to help you get started.
Upon starting the game, you'll find yourself in an apartment, this is your first Hideout (entirely free of charge, isn't that neat?). You'll receive a call from Eddie, your contact to the Cartel, asking you to come meet him.
Grab your Backpack from the top of the cupboard, get the Keys out of the cupboard, unlock the door, and head down the stairs. Feel free to explore, and when you're ready to start dealing, follow the Exclamation Point Marker on your map/compass to get to Eddie
Once you meet up with Eddie, he'll tell you to go pick up your first Dead Drop. Head over to the Green Box Marker on your map/compass and take the Drugs from the Dead Drop, it'll be marked with a white x.
The Dead Drop will contain 2x 3g Marihuana and 1x 5g Amphetamine. Head back to your apartment and open your Laptop.
This will open shadyComm, from which you can buy Drugs through Eddie, accept orders from clients and dealers, and more.
Accept your Clients orders and head downstairs and outside. Follow the Green Person Marker on your map/compass and deliver the Drugs.
Next, head back to your apartment (the Yellow House Marker and place another order with Eddie on your Laptop - I'd suggest getting an even amount of each Drug.
