Shades of Conflict is starting off as a series of disconnected missions and will ultimately culminate in a campaign. It's set in an alternate history where the USSR survived until the modern day, and a non-nuclear World War III broke out in 2010. SoC sets out to depict WW3 from multiple sides and many theaters.
Su-35s entered service in 2005 and are gradually replacing all Su-27s and some Fulcrums in Soviet VVS service. These particular airframes are forward deployed to East Germany with the 16th Air Army.
