How do you get in and out of cod campaigns? I just want to play a few, like blops 1-2 or mw1-3 or something, are they connected? I mean also is there a good ending point between either of those franchises? because they're up to bo7 and I heard that game was ass
They're all self-contained stories and the only reason to care about recurring characters is to justify the games being sequels to one another. MW2 and MW3 are fundamentally different stories with different ideas, BO1 and BO2 literally take place like 60 years apart.
