There is no campaign for multiplayer. There is multiplayer which has no storyline, there is special ops where you can do co-op to do either a kind of campaign with a storyline with a friend or do survival mode to survive as many times as possible, or there is campaign mode, which is a single-player storyline.
You get to use it in both campaign and multiplayer, but only as secondary on campaign, and in multiplayer there are entire matches for crossbow.
