Nova 6 is an experimental biochemical agent developed by Russian scientists in Call of Duty: Black Ops. Nova 6 was originally developed by Nazi Germany during the course of World War II by Friedrich Steiner and intended for use in V-2 rockets targeted at major capital cities, such as Washington, D.C. and Moscow. It was later seized, refined, and used by the Soviets. It is shown to be made of Neodymium, Rhenium and Sulfur in the Payback cutscene.
