Follow Ishi and head up the path. After you crouch under the ridge, look for the Dropkit in the rocks to the left. When you reach the cliff, use your leash to pull down the old railway car.
Head across and hold LT when prompted to. That lull in killing didn't last long! As soon as you start trekking up the slope, take out all attacking enemies. Once you arrive at the city, follow the path around to the left and kill the enemies behind the columns.
After you take care of business, hookup to the nearby Dropkit. Follow Ishi to the next area and kill all attacking enemies. When in front of the old disco club, hold RT. After Ishi opens the door, head inside.
Walk over to the right and take out the enemies up on the steps. You'll have to fight one of the bigger ones, so make sure to use annihilator blasts against him. Once he's dead, pick up his gun and use it against his minions.
