Nova 6

Nova 6 is a biochemical weapon originally developed by Nazi Scientist Friedrich Steiner to be used in V-2 rockets to target major capital cities including Washington D.C. and Moscow. With the help of Steiner, the Nova 6 was seized, refined, and finished by the Soviet Union to use against the United States. It is made from Neodymium(Nd), Rhenium(Re), and Sulphur(S).

It appears in Call of Duty: Black Ops and Call of Duty: Black Ops III, having been rediscovered by Coalescence Corporation.
