You’ll find just the one Suspected Organized Crime Activity in the Japantown subdistrict of Westbrook. These Hustles deal with a group of enemies in a larger area than Assault in Progress and you’ll need to take out all of them before looting the final stash.
Suspected Organized Crime Activity #1
To begin this Suspected Organized Crime Activity, make your way to the southern part of Japantown and head southwest from the Crescent & Broad Fast Travel. Once you reach the area, consider approaching from the upper level to the east where you can perform an easy Takedown on two unaware guards using the Crate Stack (distract the guards over to it first).
From here, slowly head down the stairs and disable the camera to your left before using the override the cameras using the panel on the wall. Continue to follow the balcony around to more stairs leading down. Don’t head all the way down however, instead leap over to the left and deal with the two guards there before turning your attention to the one at the bottom. From here, you can simply use Stealth tactics to creep up on each of the remaining enemies here to complete the Hustle.
