Call of Duty Modern Warfare Vietnam or at the very least, a Cold War backdrop? Could be, given that last year's slice of news that Activision has been licensing "Vietnam War-era music, along with Cuban, African, and Soviet Union music" for the next Call of Duty appears to have been given support by an LA casting call for the next game in the series.VG247 has come upon a
casting call note that states that character Frank Barnes, "A key player in early CIA special forces teams including 'Operation 40' Frank ultimately transfers to the
Special Operations Group (SOG) in Vietnam."
However, the note also mentions a character called Kristina Ivanova who, "has network contacts behind the Iron Curtain". She is also fluent in Russian and English.
So, we could be looking at 'Nam,
and the Bay of Pigs and the Cuban Missile crisis or even the covert recovery of the Soviet sub K-129.
