Dirty payload

Dirty payload was a slang term used by Yavian warlords to refer to a particularly unpleasant type of catapult attack, that would involve bombarding an enemy with a range of unwanted (and often dangerous) waste materials, usually with the intention of contaminating the base with toxic, explosive, radioactive or infectious matter. Dirty payloads could contain huge varieties of waste, but often contained spent nuclear fuel and toxic chemical waste products. They could also contain sewage and infected/contaminated corpses designed to spread disease to enemy monsters and soldiers. Sometimes, high grade explosives were hidden away inside the dirty payload.
