Clank holding the Blowtorch Briefcase.

The Blowtorch Briefcase, also known as the Flamethrower was a weapon that looked purely like a briefcase when it is closed. When it was opened, you could not put anything inside it because of the unremovable flamethrower. The flamethrower inside it released extremely hot fire that burned enemies. It upgraded to the Hellfire Haversack. It was made in the labs of Venantonio.
