Drive to the construction site, marked on your mini-map. Once inside, your objective is to destroy four vans belonging to the rival company. These vans are usually parked in various locations around the site. You can destroy them using firearms, explosives (if you have any), or by ramming them with a vehicle. Be aware that security guards will attack you on sight once you start causing trouble.
After destroying the vans, the workers will begin to riot, and the mission will be complete. You'll receive a cash reward and gain Avery Carrington's trust. This mission highlights the importance of strategic destruction and dealing with armed opposition. Don't be afraid to use cover and retreat if your health gets low.
