CS Boomer is a grenade launcher in QWTF spy's JC4.
Black Market description Edit
"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.
