- "C400 is the latest in plastic explosives. Created by a Kindergarten teacher who discovered that cheap clay exploded when exposed to sweat and children’s laughter, C400 has since become a disappointment worldwide. It continues to sell, however, due to a really aggressive marketing campaign and a catchy jingle involving fat laughing children sweating to the oldies. Creepy."

C400 is an explosive in Far Cry 3 Blood Dragon.
C400 is essentially identical to the C4 featured in Far Cry 3, the only real difference being its altered colour scheme. It will detonate after a given time when set, and consists of a block of C400, that Rex holds in his left hand, and a detonator remote in his right. It is a powerful anti-personnel and anti-vehicle explosive, useful against all kinds of targets.
