Just Business main article.
First off, drive to Big Smoke's house in Idlewood. Walk into the red marker, watch the cutscene if you will, after the cutscene your view will change to Big Smoke's Glendale. Now follow the marker on your minimap to the Atrium in Commerce. Stop in the red marker and watch the cutscene.
After it you will be inside the Atrium. Smoke will yell at you to get in cover. Now for a gunbattle with the Russian Mafia. You are automatically given a MAC-10 so use it to shoot the russian taking cover to your left. Then shoot his friend who is taking cover a few meters behind him. Look up at the balcony above the goon you just blasted to see another guy taking cover behid the balcony. Waste him. There should be several goons taking cover behind the Atrium's main fountain so blast them too. After there dead move out of your currunt cover and take a new cover behind the fountain. Whatch out for a russian who comes up behind you. There should be a russian coming down from the stairs where Smoke has moved, shoot him. Turn to see russians taking cover on the other side of the Atrium. Kill the two that are in cover and the other one blasting out into the open. Look up at the balcony near the stairs and shoot the goon up there. After that smoke will tell you to follow him, so do so.
You will appear outside the Atrium. Shoot the nearest goon taking cover near you and the other goon behind him. There will be another goon behind him and another one running up the stairs. Waste them then turn left up the stairs instead of going straight ahead. Once up the stairs waste any goons there. Look to your right and waste some more goons.
After they are dead you and Smoke will jump on a BF-400 and drive out of a parking lot. Once you are out you will be on the back of the bike so you can shoot any thugs that follow you. There will be a bike behind you, target the riders instead of the bike to take it out quickly. After that a Packer truck will come after you. Don't bother shooting it, its indestructible. After Smoke complains about the traffic another bike will come after you. Shoot the riders off. Smoke will do a jump over two busses. After that the pursuing Packer will smash into a bus and stop. Smoke will then halt the bike as you come to a three car roadblock. Keep shooting the middle car until it explodes and destroys it. Then turn to the front of the bike and shoot the two goons near a car in front of you. Smoke will then drive the bike down the empty flood canal. Two more bikes appear in front of you and then shoot behind you. Waste the riders. Another bike will then shoot of a bridge and land next to you, take it out. Then ANOTHER bike will jump off ANOTHER bridge. Take it out too. Then two cars will come up behind it. Aim for the gunners poking their heads out the windows to render them useless, you don't need to continuously shoot it as the driver can't do anything anyway. After that a cutscene will show the Packer jumping off a bridge and into the canal. Again don't bother shooting the Packer, as it is indestructible. Two bikes and car will also appear behind you. Kill the riders and gunner. Two more cars will shoot into the canal, one of them will get blown up from a car dropped by the packer, the other one rams into another car and blows up. Watch a ramp for more bikes. Shoot em' up, and smoke will drive up one of the canals side ramps. Another bike will jump onto the ramp, pop it. A bike and car will come up behind you. Blast em. Then a cutscene will show Smoke driving tha bike up the Packer's ramp and the cars exploding. There will be two more stationary cars in front of you. They, strangely, blow up with one shot so shoot them. Smoke will drive up to the "Old Sewer Tunnel" shoot the two thugs in front of it the shoot out its gate and smoke will drive through. Then four bikes will come up behind you. Shoot their drivers out. Smoke will then drive into a parking lot and the mission ends.
The reward for this mission is increased respect.
