At the beginning of the map, run to the left hand side and stay in the shower area. By staying in this area, the enemies will run towards you, making it easier to keep your combo going, and easier to get the gold medal.
This area also has plenty of cover, and there are three health packs in the area. One that refills 40 health and two that refill 20 health.
To obtain Gold you must earn 17,100 points and be playing on either I Am Death Incarnate! or Über difficulty.
