- "Smoke them out."
- — Warden Harm's advice to Cole
Warden Harms contacts Cole, telling him that some police officers have been watching a building they suspect the Dust Men are using as a weapons warehouse. Cole makes his way to the building, and after clearing the surrounding roofs, shuts down the air conditioning unit. The Dust Men in the building quickly evacuate, only to find a group of the Empire City Police Department waiting for them. Cole (with the officers' assistance) takes down the Dust Men, clearing the area of their influence.
Once Cole has made his way to the Historic District, Warden Harms calls for his assistance once more. His men have found a First Sons warehouse. Cole climbs to the roof and disables the air conditioner. As soon as the AC unit is destroyed, the street below is filled with First Sons abandoning the building. Cole and the police swiftly move against the First Sons soldiers, and despite the numbers and more advanced technology of the First Sons, Cole and the ECPD are able to defeat them before they have the chance to affect or harm the citizens of the Historic District.
After completion, Cole receives 100 XP and slightly reduces enemy activity in the Historic District.
- There are 25 enemies in both warehouses, however other gang members may turn up during the fight. The 25 original enemies are the ones that must defeated to complete the mission.
