Once in the vicinity of the ambush, the Courier will be spotted by members of the Viper Gang. They will start attacking immediately from both the ground and atop surrounding cliffs. Dotting the ground are several frag mines, both in plain sight and hidden underneath brush and traffic cones. Several overturned, wrecked trucks and cars rest in and around the road.
