Mission Cloacina

Mission Cloacina was a pre-War United States government science and military project.

Background
Codename "CLOACINA" was based on weaponizing a creature known as "Mutant Undermining Lifeform" or MUL, to aid the war effort, with plans to deploy them in China. The study hoped to result in covertly releasing creatures into the enemy's environment, subjecting them to their aggressive qualities, subsequently "softening the target for ground invasion." Following the invasion, a genetic kill-switch would be activated.

Development progress was successful when using a genetic stock including common sewer rats, but unsuccessful while using those infected with FEV, as the resulting creatures were sterile.

Appearances
Mission Cloacina is mentioned only in Fallout 3.
