REWARDS - Respect, $8,000, Madd Dogg for Madd Dogg unlocks
Get into a vehicle and make sure Kenny does too, then drive to the yellow blip. Once there, go inside the door and you'll have a little meeting with a certain Sindacco, who collapses at the sight of you. Now it's time to PARTY!
One of Sindacco's men throws a molotov, blocking the door with flames. Open fire on the men who come into this room, while Ken looks for an extinguisher. Make sure to protect Ken, because if he dies, you fail the mission. You must kill everyone, since they're all witnesses. As Ken puts out the flames, he tells you to start taking out guys in the next room. Strafe back and forth across the entrance, taking out the guys.
Once that's over, Ken will go and hide in the freezer. DO NOT FOLLOW HIM, since Mafia guys will come and try to close the freeze door (if you go in and get trapped, mission failure). Keep killing the guys and Ken will come out of the freezer. In the room with the boxes, slowly inch your way through the door and kill any Mafia that come into your sights. Once everyone is dead, head to the exit and get into a car with Ken, then drive him back to Caligula's to finish the mission.
