Question: are call of duty games connected?
Answer: The original 3, world at war, WW2, Modern warfare,1,2,3 and black ops 1,2,3, and 4 are all connected. Yet all follow different characters. Call of duty 1,2 and 3 are all set in WW2 where you play different campaigns(British, American, Russian, ect.) ... And Modern Warfare is in the same universe as the black ops titles.
