At nearly any part of this level, airstrikes can be called in to assist the juggernaut player with the fight against enemy forces.
The first part of this level begins with 10 enemies between the two initial chemical samples that need to be collected. One or two will likely hide in the building on the left and the rest will try to find cover behind walls or vehicles. After killing these 10 enemies, 3 reinforcements will come. Collect the two samples in the area then kill the new group of 14 soldiers.
Progress through the alley and kill the 7 enemies on the stairs. At the top of the staircase, an enemy humvee will be waiting. Kill the gunner and continue to the left (be cautious of the enemy that pops out from behind the wall on the left side). Continue through the building on the right and go up the ladder. In the next room will be 5 enemies, 2 will have riot shields. Before collecting the next sample, clear the area on the right of the humvee gunner and 4 enemies. When this area is clear, collect the sample and descend the staircase towards the next area.
The easiest way to clear this area is via airstrike. After clearing out the numerous enemies, collect the sample and continue through the building to the West. The building will have guns to resupply with. Leaving the room, go right down the alley. Kill the two enemies, take a left, and enter the building. After clearing the top floor, collect the sample, then clear out the rest of the enemies as well as the reinforcements that come through the skylight and the ground floor doors. Collect the sample then continue North into the next building, which contains several enemies (beware of riot shield enemies). Continue towards the extraction point to end the level.
