REWARDS - Respect, Big Smoke's missions unlock
You'll need to equip yourself with some weapons and end up deciding to go to Emmet's house. Drive yourself and Smoke to Emmet's house marked on the radar. Emmet seems to be a crazy old man, but he has some guns for you nonetheless. Once you pick out a 9mm, you go through a little training. Follow the tips as they give them to you. You'll go through aiming, switching targets, crouching to improve accuracy and then manual aiming.
Once you are done with training, you'll have to drive Smoke back home. Once you do that, you'll get a cell phone call from Sweet and he'll tell you to go get some green clothes from Binco's clothing store. Pull into the marker on the radar and go inside the store. Step into the marker to go inside the changing room. Remember that you need something green, but feel free to buy anything you can afford right now. Once you get some green, mission done and some more respect earned.
