Mission 137 – Destroy the Black Market Items
Come in through a locked north on the north side of the the site.
A shockingly massive security force here. Still, take something with continuous fire, pick a chokepoint, and watch them all sprint headlong into death.
If you've already hit the damage threshold for this racket (and if you've been following this walkthrough, you have), then the relevant items won't show up in Intel View. Just kill the guards, scoop up the massive piles of cash, and get ready to end this.
