PART 1: STORE SHOOT-OUT

When the mission begins, drive your associates to the lab and get ready for a shootout. Get into position and mow down the approaching Aztecas.

Eliminate the first couple of Aztecas that drive up until a pickup truck zooms past the building. From there, follow Chef outside and pick off the remaining Aztecas.

PART 2: ROOFTOP SHOOT-OUT

More Aztecas will appear from the other side of the building, so follow Chef and he'll pass you a sweet little Grenade Launcher.

PART 3: FRONT DOOR SHOOT-OUT

After blowing up several more cars, Chef prompts you to follow him downstairs. Get into cover and shoot some more of the Aztecas until Chef gives the greenlight that the coast is clear. After the baddies are gone, approach the two men in the freezer to complete the mission.
