Black Market descriptionEdit

"Forget about the CS Negotiator, the CS Boomer is like when you mix a cluster bomb with a grenade launcher. It fires a grenade, once it has landed and exploded it releases bomblets made to kill personnel and destroy vehicles."


  • The CS Boomer is a precursor to the CS Negotiator.
  • It's made by the fictional company Capstone.
