Claude drops by Luigi's Sex Club 7 looking for more work. Luigi informs him about some Diablos pimping on his turf that he wants dead and tells him to go around the back of Ammu-Nation if he needs a weapon.
Claude picks up a pistol around the back of Ammu-Nation and attacks the Diablo Stallion with the Diablo and the pimp, killing them both.
Some Diablo scumbag has been pimping his skuzzy bitches in my backyard. Go and take care of things for me. If you need a piece go around the back of AmmuNation opposite the subway.
Claude finds and kills the pimp.
Kill the shotgun-toting gangster first! Shotguns are dangerous even at the late game, and at this early mission when you are likely to have few weapons and low ammo they are even more dangerous. Keep firing at him, don't let him fire his shotgun or he will heavily dent your health, and knock you down.
Grab a body armor to cushion possible shots, this will also teach you to know the locations where body armor spawns, and get used to drive around the city to pick them up.
Use the services of a prostitute, she will increase your health from 100 to 125, another useful lesson that will help you through the entire game.
The reward for completion of the mission is $4,000. The mission The Fuzz Ball for Luigi Goterelli is unlocked and the pistol becomes available for purchase at Portland Island's Ammu-Nation.
Two unnamed pimps - Killed by Claude for pimping around Luigi's turf.
