Call of Eroica: Orange Stories is centered off of the origin story of Mark Anderson, and his first battles against the Anti Fandom Waffen-SS. His first battle is at the Battle of Paris, where he killed 57 Anti Fandom troops on his own before falling back. His second mission was a failed assassination attempt against Mepios, which resulted in Alexander Davis(Jack Davis's brother) dying. The third and fourth missions are one mission, but at different times. The first one is arriving in Berlin, and the second is the Fall of Berlin. His last mission is in a Labor Camp set up by the Anti Fandom Waffen-SS, where he manages to escape(Fun fact: that's the same camp Jack Davis also was at).
