It is 1946. The Allies have defeated the Third Reich — but RedStar intelligence has received alarming news. A Nazi group called Cobra has been operating in a castle in northern Germany, developing a weapon under a scientist known as Dead Eye, whose life project is called Iron Heart. The covert Omega team sent to investigate went silent. Russian agent Viktor Baklazhovich, codenamed Shadow, is deployed to rescue them — and is immediately captured. Freed by another agent, Viktor must now find who is pulling Friedrich Hartmann's strings and stop the Third Reich's final plan.
